How To Make Backup Copies Of Your "Peronal" DVDs

Simple method

 

Things you need:

Smart ripper

Nero Burning Rom (latest version supports burning to the DVD)

Your Favourite Software DVD playback program (Cyberlink PowerDVD is a good one!)

 

Begin!

 

 

Now, this is the MAIN menu of Smart ripper. It tells you details about nearly everything on the DVD it has authenticated to. If for some reason, authentication was UNSUCCESSFUL, then usually this means that the DVD is highly decrypted. What you need to do is to run your favourite DVD playback software, watch the DVD for a few minutes, this will decrypt the DVD and then shutdown the software and run Smart ripper quickly. Then it should be authenticated.

OK, now click on the target button (marked as 1 in the screenshot), and change to the directory you wish to save your ripped VOB files from the DVD. Once done, click on Settings (marked as 2 in the screenshot). Make sure that the settings match up with these:

 

 

I think, either the IFO or the Info file contains the information about the DVD and how many chapters or tracks there are in that movie. This is REALLY needed when loading the VOB's in DVD2AVI to create a project file to use within TMPGEnc or Nandub encoding.

Click OK and once done, click on Start!!!!!! LET IT RIP BABY!!!!!!!!!!

 

The ripping process can take up to 20 minutes to about an hour, depending on how fast your DVD ROM drive and and your system and how heavily encoded the DVD is. Now, make sure that the speed of the DVD, when ripping is really about 4x below the speed of your DVD ROM, the reason being is because the DVD ROM DRIVE and DVD ROM CAN go on fire due to the encryption on the DVD. If you see anything bad happening, cancel it immediately at once. Generally it doesn't happen but it's better to be safe than sorry!

 

 

Well, once it's done a friendly done message will appear, next is to load up Nero Burning Rom and create a new DVD compilation. then drag and drop the ripped VOB files into Nero and burn it to the DVD-R, preferably, burn it at a lower speed for safety. Once it's done, make sure it plays on your PC and if it does, it will play back on your DVD player!

Enjoy! :)

Making Backup's of DVD's

The Hard Way

 

Well, this part is really the recommended way of doing backups of DVD's. You can also cut out the bits you want and also, brighten up the picture and edit some stuff before encoding the DVD. So, it does have a few more advantages than just to "rip 'n' burn".

Follow the guide above to rip the DVD, then you need these tools to continue:

 

Things you Need:

 

TMPGEnc

DVD2AVI plugin for TMPGEnc*

DVD2AVI v1.76*

DVD Burner (recommended of course for this process!)

Nero Burning Rom

 

Begin!

 

 Now, you may have noticed that I put an asterix (*) in front of the DVD2AVI. The reason being is because sometimes, TMPGEnc doesn't like to encode the VOB directly, so DVD2AVI acts as a "bridge" or "patch" to kind of, solve the problem.

Well, I'm going to use the DVD2AVI method, but if you folks don't want to, just skip to the part down to where you see TMPGEnc and load the VOB, instead of the DVD2AVI project file.

 

Install and run DVD2AVI (Make sure it is v1.76 otherwise it will NOT work!). Once you have opened the first VOB in the directory, this will appear, just click on OK:

 

 

Now, slide the slider along and skip to some parts of the movie, making sure it is OK. If not, then well, the decryption was not good enough which means you need better DVD playback software!

Go to File > Save project and type in a file name to save the project. This will create a D2V file in order to load it into TMPGEnc or Nandub. It will take some time saving again, about 20 minutes:

 

This will also save the audio track.

Note about DVD Audio:

 

   DVD Audio is encoded and saved at 48000Hz (48KHz). Now, if you face a/v synch issues (audio is faster than video or vice versa) then it is better to down sample to 44100Hz (44.1KHz), which is CD quality. Usually, this is not a problem, since we are ending up making a backup of a DVD. However, if it was to some other method (like VCD, DIVX or SVCD) then we would have to down sample. Check out Method 1 in my DIVX guides on how to down sample.

 

Back to where we were...

 

Take a note of the Region of your DVD. the frame rate and also the aspect ratio, this is needed for the TMPGEnc settings. Otherwise your DVD result will end up as something you don't want!

OK cool, you just made a project file in DVD2AVI. now, unzip and install TMPGEnc with the DVD2AVI plug-in. Now, what DVD2AVI has also done is that it saved the audio track of the VOB file, this audio track is in a Wav file.

When you load up TMPGEnc, you will be presented with a wizard like the following. If you have a PAL region DVD, select PAL DVD, otherwise, if it is an NTSC region DVD, select NTSC. The bitrate as another thing, of course, the higher bitrate, the better quality BUT bigger file size. Make sure you know the length of the movie before choosing a bitrate. usually a typical movie is about 1 hour 20-30 minutes so the default bitrate assigned is perfect (that is CBR 4000KBPS):

 

Click Next

In the video file, browse to the D2V file we just saved and load it. It will automatically judge the fielding order:

 

Once that is done, load the wav file that DVD2AVI saved from the VOB in the audio file box:

 

Now, remember I was saying to keep a note of the aspect ratio of your DVD? Well, this is the place to select it. The aspect ratio is like, whether or not the DVD is widescreen or cinema scope or a FULL screen. My DVD was Widescreen (16:9) so I select 16:9 PAL (because my DVD is a PAL!).

The field order is what TMPGEnc did earlier on when it loaded the D2V file. It has set it to B, which is digital format, and A is analogue format (from captured material).

Leave everything and click Next.

Now, you may want to cut the end credits out the movie, if so, select source range and mark the start and ending positions of the movie you want to encode. You can also brighten up the picture if you like. Once you selected your settings, click on Other Settings and go to to the advanced tab:

 

 

Select Full Screen (Keep aspect ratio) from the Video arrange Method combo/drop down box. This makes sure that the movie is encoded widescreen/cinema scope etc...

Once that's done, click on OK and click next.

 If you find that you have a lot of free room on the DVD left (TMPGEnc tells you if your DVD-R is going to be full or not after the encoding), you can select a higher bitrate, by going back to the start of the wizard and selecting a higher bitrate. Again, it means higher quality and bigger file size. Make sure it doesn't over encode it other wise the movie will NOT fit on the DVD. Once done, browse and save the file to a destination on your HDD. Click OK and TMPGEnc will now encode the movie. it will take a lot of time so, sit back and relax.

 

Once it has been done encoding, watch the movie. Make sure everything is according to your expectations, make sure that the audio and video are not out of synch. When satisfied, burn the movie as a DVD using Nero Burning Rom! And then well, watch the movie on the DVD player!!!!



Convert DVD's to VCD using DVDx


There are many different ways today in making VCD's from different Sources. Some people like making VCD's from their own DV (captured from DV to PC and converted to VCD), or from DVD's, or even from DIVX files. VCD is now really, the BASIC STANDARD of viewing Videos, nearly ALL DVD players (standalone) support VCD playback. VCD is MPEG1 at a constant Bitrate of 1150 kb/s. It's very easy creating a VCD, and it can take some time converting from 1 format to another, due to compression, the source type, the lenght of the video file, the scene changes etc... Today, I am making a guide for you people, to create a VCD STRAIGHT from a DVD. The quality can vary, all the time. It depends on the original source and the software and settings you use. In my experience, I think TMPGEnc is the easiest and best out of them all sue to the ease of use and advanced features in it.


Let's Begin!



Tools YOU Need:

Smart Ripper (preferably v2.41) Smart Ripper
DVDx (I am using version 2.0) DVDx

VCD burning software (nero or adaptec)

Now, we have to "rip" the DVD we want to create a VCD out of, to the HDD, we use smartripper for this. The reason we have to rip the DVD to the hdd is because of the encryption on the DVD itself, and also, encoding from a DVD to a HDD can take VERY LONG, and also, there is a risk of the DVD going on fire due to the encryption and the amount of information held on the DVD. HDD's are the fastest thing in your Machine (with speeds from 5400RPM to 7200RPM IDE). Open smart ripper, you will have this screen:



 

Just before that, you will have a small screen where Smartripper analyses the DVD in the drive. It tries to read it and makes sure that it can rip. If it can't, then you have to play the DVD for a few mintues with DVD playback software, as this will get rid of the encryption for a while. Once authentication is done, you will be presented with the screen above. Everything is really set, you just have to specify the target directory that you wish to use to save the ripped files from the DVD. Make sure you have over 10GB free space (this includes the encoding etc...) You can delete the VOB's when the full process is done (that is, after we convert to VCD)

Well, what are you waiting for??? HIT START!!!!!!




This is the smart ripper status screen, it tells you very detailed info. The rip can take anything from 10-20+ mins, depending on the length of the movie and also the speed of your DVD drive.

Once done, you will recieve a friendly messege from smartripper:





Ok, now the DVD is ripped, that was a real hard job, why? well, simple:

When ripping DVD's, Some HIGH ENCRYPTED DVD's are very clever when DVD ripping software is trying to Rip the DVD. This can cause your DVD drive to go on fire, believe me, I have seen it and read it! So, be VERY careful. Use this version of smart ripper (SR241) because that is the safest out of the whole lot!

Right, download and install DVDx v2.0 and open it, this is what you should get:



Very pretty, isn't it? Better than the other version, I think so anyway. I haven't tested it so, this is the first time I am using DVDx v2.0, and I thought, well, why not use it and make a guide at the same time? So, here I am :) There are 2 version of DVDx when you install it, a version for all other computers that are NOT a Pentium 4, and a special version for the P4. Why? Because INTEL rule! They made a special version for the P4 because of it's enhancement, better graphics and sound. And also, sometimes a faster encode. :)

OK, goto file > open DVD root, and select the DVD you have just ripped. Select the correct VOB, you can tell by the length of program/video:




Once you hit the select button, you will have the input settings Window:




Well, nearly everything is done for us, great! Change the Audio to this option:

"High Quality 48KHz to 44.1KHz". The reason:

Every conversion (DVD/VCD/SVCD/VDC) has a "compliance" and if it doesn't meet the compliance then it is not compatable. So, if we leave it at 48KHz, the CD-Writing software will NOT burn the file and you cannot view it on you standalone DVD player. Also, Some sound card do not support 48KHz. It can cause A/V synch issues and sometimes it can sound like ASF streaming format. We are "DOWNSAMPLING" from one frequency to another, 44.1KHz is a frequency used by audio CD's, and it is REALLY good quality. HIGH quality. If we downsample from 48KHz to 44.1KHz, we will NOT lose quality. it will keep the same quality, but just lowered a frequency. It's simple :)

Just to make sure we do not have A/V synch issues, select the "Audio/Video synchronisation" check box. If you want to shut your PC down automatically when the job is done, check the "Shutdown the computer when job is done" check box. Finally, select the output frame rate you want for your region. 25fps is PAL, so I chose that, 29.97 is NTSC frame rate so choose that if you are in an NTSC region.

If your movie, in the end, comes out bad where there are "lines" in the colours of Red, Blue and or Green, then that means that the video needs to have a de-interlace filter. VCD has this problem so by applying this de-interlace filter, it should sort out most of the problem. It will take more time to encode but it's worth it.

Hit OK.

You will recieve this error message:




Ignore it, it is a bug, still hasn't been fixed from DVDx v1.8, the last time I used it!

Anyway, things will work fine. Now, we have to selct our output settings, so goto Settings > output settings and a window will appear:




Select the format you want the video to be converted to, we are making a VCD so choose VCD (MPEG1):

VCD = MPEG1 (with a CBR of 1150KB/s) = Low quality
SVCD = MPEG2 = High quality
DVD = MPEG2 (HIGH Bitrate) = High Quality


anything else done in MPEG, is not a VCD/SVCD/DVD. It's just and MPEG file!

The audio bitrate is set to 224 as this is the standard compliance. Generally speaking, the higher bitrate, the better quality BUT a bit higher on file size.

Motion Search : This is nearly the same as TMPGENC (I prefer TMPGENC), this setting is fine as it is (normal (fast)) but if you want a higher quality, select "High (slow)" This will take about 8-12 hours to encode, quality is SOMETIMES, OK, but leave it were it is, this will take about 4-5 hours to encode.

Leave everything else and move to the right hand side! :)

Leave the Res, but if we were making a DIVX file/AVI then you can change the res. GENERALLY speaking, the higher the res, the better quality but file size will increase, ALOT. I love my captured stuff at 352*288/320*240 and it gives me NEAR DVD quality, and LOW file size.

For the "Zoom" section, if the movie was Widescreen (16:9), choose 16:9, otherwise choose 4:3. All it is, is the black bars get put in the movie, top and bottom, that's all.

Now, you may wish to encode all or part of the movie, if you want to encode the WHOLE movie, click the WHOLE button. Otherwise, enter the frames (from 0 to x) you want to encode to. For example, I might want to encode half of the movie so the frames I want to encode will be 69187.

You can also tell DVDx to encode up to a certain file size!!! This is handy for doing DIVX files, as it will stop when it has reached to the entered file size and start a new file and continue with the encoding! So, 2 jobs done in 1 :)

Since we are making a VCD, it is not necessary. As long as the movie is in the length of the capacity of CD (80 mins) then we are fine, regardless what the file size will be. If the file size is more than 700MB but the movie is still less than 80mins, NERO will burn it!!!! How? Because it uses timescale, NOT file size. Clever!!!

Hit Apply

Now, one of the most FINAL AND CRUCIAL moment is here. We must encode our file to the chosen format (VCD in this case) Hit the Red button, that looks like a record button.

Once done, play it back, do you like it??????

Some videos are better looking than others. But remember, VCD is NOT a good format! If you want to make a good video, and your DVD player supports it, convert to SVCD or DVD (If you have a DVD writer!)


 


Converting DIVX to DVD

 

 

Things you Need!:

TMPGEnc

Nero Burning Rom

Virtualdub (for Audio)

*WAVELAB*

 

BEGIN!

 

Before I launch the fireworks for this guide, I put in Virtualdub and Wavelab (or another down sampler program), the reason being is because some DIVX files do not contain the correct audio frequency. Sometimes, if everything is perfect, you can't hear the audio, if this is the case, simply load of Virtualdub, then:

 

1) Open the DIVX file

2) Go to audio > full processing mode

3) Go to audio > compression > NO compression (PCM)

4) Go to file > save as wav and save the audio track.

However, if this does not apply, then if the audio frequency rate is 48000Hz (48KHz) then please downsample to CD Quality (44100Hz/44.1Khz) using Wavelab or another downsampler program of your choice. I personally recommend saving the audio as wav first before converting everything in a "oner"

 

OK, let's get started! Once you got your movie chosen, simply load up TMPGEnc and follow the wizard:

 

 

 

Again, if you live in a PAL region, select PAL, or if you live in NTSC region, select NTSC. Also, choose the correct length time of the DIVX movie, because the bitrate has to be assigned accordingly otherwise the file will be too big or too small. The higher the bitrate, the better quality BUT larger file size.

Make sure you know the aspect ratio of your DIVX file, if it's widescreen, it's 16:9 otherwise 4:3 (VERY rarely do you see a FULL SCREEN 1:1 DIVX movie):

 

Also, browse to the saved WAV file, this will encode the audio with the movie.

Now, we all know the DIVX is a HIGHLY compressed video file. Thus, many programs will see the video containing up to 3 times the length of the movie! So, in order to avoid this problem in TMPGEnc, simple select source range and mark the starting and end positions of the movie, TMPGEnc will encode the selected source range:

 

Move to the start of the movie and hit "Set start frame". Then move to the end of the movie (or if you want to cut the end credits, move to the beginning of the end credits) and hit "Set end frame" Then click on OK.

 

Click on "other settings". Here, we can brighten up the picture if we wanted, which is ideal, or do other things. One thing we must do is make sure that 10 bits is selected for the "DC component precision". This makes the movie smoother than jerky moves.

 If you want HIGH quality (and time is not an expense for you) then select to encode it at HIGH quality. DO NOT choose to encode at "VERY HIGH QUALITY" as this can sometimes over do the file, and you will notice a lot of bad quality in the movie, since the original source is high quality anyway.

Click on the advanced tab, and you will see this:

Everything here is correct, but, in order for the movie to be viewed at the correct aspect ratio, select FULL SCREEN (Keep aspect ratio) in the Video arrange method. This will certainly correctly encode and display the movie. While you are here, increase the brightness by 10+

 That's you done! The encoding process will take a lot of time, about 7-9 hours, so it's best to leave the PC on over night and select the "Automatically shutdown computer" check box in the main editor window. This will of course, shut down your PC once everything is encoded!

Once it's encoded, check the MPEG file. Make sure Audio and Video are in place, so there are no A/V Synch issues. After that, burn it in Nero Burning ROM as a DVD and write to the DVD at the lowest speed. 



Cutting Parts of Videos Using Virtualdub




SOOOOOOO MANY people have asked me this question. Answers are in forums, but, for some reason, they do not wish to look for it - which is fine by me, I like helping out.

Thanks to you guys, Technosoft 2000.co.uk has been a BIG Hit for DIVX and also, for programming, I just wanna say thanks and I hope I keep providing you the best and top quality information, in all aspects of this site.


Cutting Videos, or parts of it!



Well, simply put, the reason we would like to cut videos is because either:

1) The file size is too big to fit on X amount of CD's
2) We just don't like that scene/part of the video in our final file

That's really the reason, sometimes the other reason is that some videos get "frozon" (known as freeze frames). There are 3rd part utilities to clear that up but sometimes it is more serious the the utilities can either:

1) Get locked themselves
2) They just don't have the strength to fix it


So in Virtualdub (or nandub, sister of Virtualdub), we can cut out the part that is causing the problem, usually, about 5 frames of it.



Let's get started!


1) Open Virtualdub
2) Open the video we wish to edit


Here are the standard Virtualdub (VD) tools




It is really simple, I am just going to highlight the MAIN tools we are going to use.

Let's say, our situation is that a movie is too big to fit on 1 CD, and must be fitted on 2 CD's (depending on the size of the movie of course!), how do we do that?



SIMPLE



1) Hit the Start marker button
2) Move the Slider to the part of the movie where you wish to cut up to
3) Hit the End marker to stop marking the movie
4) You will see that the part selected/marked has been highlighted:








OK, as you can see, that should happen to you, that's great. Now, if we want to save the selected part to a file, we must make sure that the audio and video are copied EXACTLY. Otherwise, we will have a discombobulated jibbry jibberish file (actually, a HUGH file, and may have A/V synch issues). In order to sort this part out, do the following:


1) Goto Video > DIRECT STREAM COPY
2) Goto Audio > DIRECT STREAM COPY

That's it, that part is self explanitary, It copies that part EXACTLY, as it is.

Now : 3) Goto file > Save as AVI and save the file.

In a few secs, the selected part of the video will be saved to a new file. Simple, eh?


If you wanted to delete the selcted part, simply HIT DELETE on your keyboard. That's all! Then:


1) Goto Video > DIRECT STREAM COPY
2) Goto Audio > DIRECT STREAM COPY
3) Mark the whole movie/the part you wish to save
4) File > Save as AVI
5) Save it



 

DivX to VCD Conversion Guide

I have been working on a good way (with tCi) to convert DivX movies to VCD format (to play on a dvd/vcd player) for a while. We've come up with a pretty good way that has excellent results.

Note: Using bigger DVD rips is always the best choice. The bigger (and better) the original rip is, the better quality your final vcd will be. I have found that [smr] rips are not the best to use during conversion.


Step 1: Splitting the movie
First of all, you must know that when burning the CD, you will not be able to fit more than 70 minutes of the movie (just like when burning music). However, the difference here is that the higher the quality, the less you are able to fit. If you convert at 100% quality, you will not be able to fit more than 60minutes of the movie on a single CD (I do not know the exact time restraints, however this is fairly close).

When splitting the movie, DO NOT use Avi Chopper. This can create corrupted split files (you will not be able to join them back again). So, you use VirtualDub. This is done by selecting the first half of the movie, and deleting it. You save that half. Then select the second half of the movie, and save that remaining half. It's fairly simple and gives the best results (also allows you to cut at the beginning of a scene instead of in the middle of the scene).

Step 2: Uncompressing the audio
You must uncompress the audio of a DivX in order for the mpeg-1 to be burnable as a VCD.

To do this, use VirtualDub. Put the Video on "Direct Streaming" and the audio on "Full processing mode." In the audio section, go to "compression" and select the empty space " ".

Then save the Avi as is. This should not take very long, however will produce a much larger file (normally around 75% to 100% larger).

Step 3: Converting Avi to Mpeg-1
This is usually a very long process (depending on your cpu, RAM and the amount of changes you make, it can take anywhere between 6 and 40 hours). It also create a fairly large file (100-500mb larger than the uncompressed avi). The program to use in this is called "TMPGEnc." (The Mpg Encoder) FYI, this program is supposedly optimized for AMD processors.

The first step is to select the audio and video sources (both the same file) and then to select the output file (the file which will be created after conversion). Select the "configure" button to set up the aspects and quality.

Video tab:
Stream type: Mpeg-1
Size: 352x240 (must be this size!!)
Aspect Ratio: 4:3 525line (this can vary depending on the rip and the dvd player- but 4:3 usually works best)
Frame Rate: 29.97fps
Rate Control Mode: Constant Image Quality. Then go to the settings and change the quality to 100 and the maximum bitrate to 100 000.
Motion Search Accuracy: Highest Quality (very slow)

Advanced tab:
Source aspect ratio: This can be changed depending on the rip that you have. Try to find out the aspect of your rip. Otherwise pick one at random as this does not seem to make THAT much of a difference usually.
Image Positioning Method: Fit to Frame (preserve aspect ratio)
In the area below, select the following boxes- Ghost Reduction, Noise Reduction, Edge Enhancement, Basic Colour Correction, Crop Video, Audio Effects

Audio tab:
Stream type: Mpeg-1 Audio Layer II
Sampling Frequency: 44100 (must be this!!!)
Channel mode: Stereo

System tab:
Stream type: Mpeg-1 Video CD

Anything I did not mention should be left at it's default setting.

Then you just Click ENCODE!!! That should be it. My advice is to cancel the conversion after a small portion is completed and check the mpeg file to make sure the size and aspect is ok and that nothing is cut out from the movie. If something is wrong, selecting a different aspect ratio (both source and final) will usually work.

This is the best method I have seen for the amount of time it takes. Very good quality depending on the original DivX rip.


How to rip DVD's:

Method:

SmartRipper, DVD2AVI, Vob2Audio, Wavelab, GordianKnot, Nandub, Virtualdub MP3

Video = smartripper, dvd2avi, gk, nandub,

Audio = vob2audio, wavelab

 

Things u need:

DIVX 3.11alpha codec

Smartripper

Dvd2avi v1.76 ONLY!!!

GordianKnot

Nandub

Virtualdub MP3

Vob2audio

Wavelab FULL VERSION

 

 

Typical HDD space needed:

10-20GB For dvd rip, sound and nandub encoding, but you may delete the vob files and sound files after nandub 2pass, leaving only the DIVX DVD rip file.

 

DIVX 3.11alpha

 

The reason I chose DIVX 3.11alpha is because it is the best codec, for me anyway. I usually capture stuff, encode to MPEG2 then to DIVX fast motion and works like a charm. this codec also produces HIGH quality for LESS file size, unlike DIVX 4 and 5, even after a 2pass method! Sorry folks if you think I am talking Bull, but this is what I think, and it is my opinion. I do my experiments and testing before I make a judge. Try doing the same thing in this guide with DIVX 4 and 5, you will not get the same quality or file size!

 

Begin!

 

Rip the dvd using smartripper. If u get an error message like "can't unlock dvd" then play the dvd for a while using windvd/powerdvd. Then run smartripper again, it should read the dvd and give an "authentication successful" message.

OK, this is good, now hit the settings button in smartripper and then change to these settings:

 

 

OK go back to the previous screen. At the bottom of that screen, there should be a "target" button, this is the location to save the VOB's, enter a location to save the VOB's (ripping):

 

 

Now click START!!!!!!!

You should get this screen, just sit back and watch, or have a little snooze, make sure your DVD drive does not go on fire:

 

 

This will take a while, after the rip is complete, you should have this message:

 

 

Well done if u got it! If you haven't then try again, or use a latest version of the software. If no luck, try a difference DVD drive,

Now we need to make some sort of project, in order for other software to read the vob's, we may need to resize (crop) the video. For this, we use DVD2avi. Download v1.76!!!!! Not any other version, u will find out why later on. Open the first vob ripped to your hdd (something like vts_01_1.vob), then a box will appear, click ok:

 

 

Play a little bit of this, go to Option > Preview or just hit F5. There will be a stats window on the right hand side, take a note of all the stuff it says:

 

You must take a note of the Aspect Ratio, the frame rate, the video type, the frame type. This is really pretty much it.

Goto audio > track > none. We will be extracting the audio later using vob2audio

 

Then goto file > save project and type a name and save it. If a project already exists, make a New Folder and save it there. It will now scan the video and put the info in the project file.

This will take a while.

When it is done, close the dvd2avi program and run vob2audio:

 

 

The vob list is the file in the directory that you had ripped the dvd's to. so, load this file. In the audiostream, select the AC3 0x80 track, as this is normally the audio of the film/movie. Sometimes it can change, depending on how the DVD was burned/made.

Then select a destination to store the audio. CHANGE THE NAME of the file you are going to save it as, as vob2audio will not accept the default file name. After this has been done, hit the start button, it will now decode the ac3 audio to a wav file. Just wait till it finishes:

 

 

It may take up to 1 hour, so make sure you have got time to do this.

After this is done, try to get your self a full copy of wavelab. Load it and load in the wav file, that u have just decoded from an ac3 file. Change the sample frequency rate to 44100Hz. The reason for this is because, some older sound cards cannot handle 48000Hz. Also, sometimes it sounds like ASF audio file, so quality is not good. 44100Hz will NOT lose quality, not much anyway. 44100Hz is the sample rate of CD's too. It will still sound like DVD quality. And sometimes it can cause a/v out of synch.

To change the sample rate, GO TO Process > Convert sample rate and select the 44.1KHz radio button and hit OK. This will change the sample rate.

 

 

When you have done this, go to file > save special > encode as MP3. We need to make the MP3 a CBR, so virtualdub accepts it.

 

 

Change the CBR settings to either, the default or to 44100Hz 160 bitrate. Then Click OK. A box will appear to save the file, change it to a directory to save the file and type a filename to save it. It will encode. May take about a half hour, depending on your CPU speed.

 

 

Once this is done, get Gordianknot. We are going to calculate bitrate and crop the video from the dvd2avi project file. After this, we are going to save the Gordianknot project so nandub can accept it as a file/video source.

 

Start up GordianKnot and goto the Bitrate tab/section. Enter the amount of CD's you wish to make the DIVX fit on. Select 3.11alpha and open the dvd2avi project file. A preview windows will appear. If you use a different version of dvd2avi, GordianKnot will complain about the file version not matching and will say to make sure it is a dvd2avi v1.76 file.

 

Now, copy these settings:

 

 

 

1 = select the CBR MP3 file we have just created.

2 = set the amount of CD's/Final File size you would like. The bitrate get's calculated automatically underneath it.

3 = Open the DVD2AVI file project we created earlier.

 

Now, select the Resolution tab.

In the "Crop (before resize!)", select Smart crop all, and control the cropping using the slider or by entering the new size in the bolded, WIDTH x HEIGHT.

I have chosen 480x256.

   The reason to crop is because, if you see any macro blocks, this means that not enough bitrate is going to that area. Black takes up A LOT of bitrate, so by cropping that black part, it will "re-use" the bitrate somewhere else when needed, so this means less macroblocks will appear or SMALLER macro blocks will appear.

   In the preview windows, select the "save and encode" button, and hit the save button. Select a file name and hit save. You can now close GordianKnot.

 

NANDUB

 NANDUB is a HIGH 2pass encoder. Nandub is based on SBC (Smart Bitrate Control), basically, uses both, low and fast motion when encoding. The controls are similar to Virtualdub, because it is "Hacked" (with permission) and also is based on VirtualDub. The SBC cleverly detects the motion of the scene and adjusts the bitrate/codec accordingly. More information on Nandub could be found on

 

Now, let us get started on our final step. This will take about 6-8 hours in total for a 2pass, takes longer but quality is worth it!

Open the GordianKnot project file we just created. Goto Video > SBC options > bitrate calulator:

 

 

 

Again, calculate the bitrate. This time, we do not use the audio at all. We do this calculation:

 

The capacity of CD - the size of the CBR MP3 audio = our final VIDEO size.

 

Enter the answer in the final size of the bitrate calculator.

 

 

Hit OK and go to video > SBC option > SBC settings.

click on the compression level tab, leave everything else.

in the keyframe options, enter 2 and 4.

 

 

I really have no idea what it does! Someone told me to do it for better quality, look on divx-digest for more info.

Hit OK and make sure that in the audio options, it says "no audio".

Now, go to File > Two passes and enter the filenames of the avi and the stats that nandub makes.

Nandub now does Pass 1 of 2. The file size will go up and down, this will take about 4 hours per pass or less.

 

 

 

In the second pass of 2, the file size will go down to about the same file size as the calculation we have done.

Leave your PC on over night and hit the "Shut down when finished" check box so your PC switches off automatically when encoded. Leave your PC on so it has the freedom to do "more" overnight, if it causes you bother during the day.

I have just done this, woken up this morning, the PC was switched off automatically. I watched the video and the quality is superb!!!! Just like DVD!

Now we have to add the MP3 audio, we use Virtualdub MP3 version for this.

Open the 2pass encoded video, and in the video options, select "Direct Stream Copy".

Goto audio and select MP3 audio and select "Direct Stream Copy".

Now go to file and save as and enter a file name.

It will save the video in 15 Mins.

Now open the video in WMP, the quality should be DVD!!!!

 



How to RIP DVD's Guide 2

 

Method:

Smart ripper, DVDx

Tools needed:

DIVX 3.11alpha codec, Smart ripper, DVDx, Your Patience, coffee and a hammer :)

 

I had used the same DVD as in Guide 1, but used fast motion to encode because:

1) I had encoded using the SAME bitrate in nandub but the quality was poor, artifacts, blocks etc...

2) I used a HIGHER bitrate but the quality did not improve even though the file size was SLIGHTLY bigger

3) I tried over 4 times using Low motion but no luck!

 

Today, I have used Fast motion - Many people say it is crap, load of garbage, well, let me tell you something, it isn't! Why? Because:

1) I do capturing. I convert to MPEG2 then to DIVX fast motion with 6000 bitrate and gives excellent quality for LOW file size.

2) The file size is LOW! :)

3) Encodes faster

 

OK, let us start by ripping the DVD, again, use the same settings in Guide 1 using smart ripper. Sorry folks, the reason I did not put up the pics of ripping the DVD in this guide was simply because of bandwidth issues, but please check out guide 1 for ripping the DVD.

Once the DVD is ripped, we simply load the IFO in DVDx:

 

Then this box will appear automatically:

 

Here is a little explanation on what some of the settings mean:

Program Chain: Most of movies are stored in angle1. You can select the program chain index and the angle to a different one if you know which one the movie is stored in. Note that DVDx doen't support all DVD features so you may get the "MPEG2Dec: Error during initialisation" error when opening some index's.

DeCSS: Keep default setting for DeCSS, ASPI is needed for the drive authentification and let's you read files bigger than 1GB sometimes. Change the key search mode if you get scrambled picture.

Audio: We select a higher volume setting if the encoded file's volume is low. We can also select the types of quality we want the audio to be decoded to. It is good to keep it at 5 instead of the default of 3

Frame Rate: We can change the output frame rate if we wish but this will cause a/v synch, were the audi and video to not match.

Subtitle: Select subtitle. Original color preserves colors from the IFO file. Uncheck the flag if you get bad looking font. Vertical offset allows you displace the subtitle verticaly on the screen. This text was written in the manual of dvdx, you get a HTML file with DVDx, most of the descriptions and settings are written there.

iDCT: Leave this alone, changes the quality.

A/V synchronisation : This tried to match the audio and video together to match them up, but we do not use this as we are downsampling and also not using AC3 audio.

De-interlace filter : If your movie has lines going across the screen, then you movie needs to be de-interlaced, you can use this option to improve the quality but it will take some time encoding

The rest of the options are self explanatry. It is a matter of experimenting to get the right quality for your viewing pleasure.

Click OK and you will be presented with a preview screen. Remember, if you move the slider and encode, it will start encoding from where the slider is, so it won't encode all the movie, it will start encoding from where the slider is!

Now, the movie I took was widescreen (16:9). If I choose the codec I wanted to encode to and the audio settings, it would produce a very squished picture, not good! In order to fix this, we need to change the ratio to 4:3 so it looks like the DVD picture, still in widescreen mode. We need to change this in the settings menu:

 

 

This setting (marked in red) shows the output when encoding, so you know what it looks like while it is encoding, so you don't have to spend 4-5 hours to encode and find out that it was a very small/squished picture!

 

But to REALLY make the output 4:3 display, we goto the "Adjust output resolution" and select "correct 4:3". There will be a message box appearing, saying that the resolution will change to (X,Y) output:

 

You just continue.

Now, to choose the output settings (audio codec, video codec), we goto settings > output settings. You will see a box like this:

 

 

DVDx can encode VCD's and SVCD's and AVI's, very good stuff! :)

We want to encode our DVD to DIVX, so we choose AVI (DIVX, YUV,...) from the drop down box. We then choose the resolution we want to make the DIVX file, I have choosen 480x256.

A BIT ABOUT RESOLUTIONS:

 

If you find that your video is blocky (macroblocks or artifacts) then REDUCE the resolution. The reason for this is because, if the source (ANY SOURCE) has some blocks, that you may not notice, then the bigger resolution you put for the output, you will notice MORE of the blocks. If you reduce the resolution, then you will notice LESS of the macroblocks! It sounds stupid I know, but this is the way it goes, it is some sort of "Science" behind it that I cannot figure out!

So what I am basically saying is that, if you have some blocks, reduce the resolution, but if that does not solve it then you must crop it. Cropping will let you choose what to crop (X or Y). It would be a good idea if you crop the black bars, as the codec will use the bitrate on the black bars because the codec does not know that there are black bars, so you will notice less of the artifacts and blocks, this means that if there were blocks and artifacts then there is not enough bitrate going through the area affected. If you increase the bitrate, it will improve the quality but file size will be bigger and may not neccessary remove the artifacts or blocks. When you crop it, it will assign the bitrate to a different area where needed. It makes the codec work harder on the bars than instead of trying to encode it. More on this topic can be found on DIVX-DIGEST.com in Nicky guides.

If you increase the resolution then increase the bitrate too as it needs more of it because it has a larger area to cover. I am currently testing different resolutions with different bitrates and am trying to make sure the video fits on 1CD (700MB). Results will be posted up here once I have finished testing.

 

Back to where we were.....

 We need to set the audio bitrate, you may choose which ever bitrate you would like to use. The higher bitrate, the better quality and bigger file size. I have chosen 128kbps 44100Hz because that is the "standard of MP3's" and will not lose much quality. Actually, sometimes it can be the same quality for some strange reason. LAME is a good codec and so is RADIUM for MP3's, but for some reason, DVDx was programmed to use LAME. There are other options too if you want to save your audio as a different format, like WAV, AC3 etc... But we choose MP3 as this is what 90% of DIVX encoders (people) do.

We can also set the quality (Q1 = Very high quality = more time to encode) but I haven't touched this at all. I left it to the default (Q3).

You can change the audio channel if you wish to.

 

A BIT ABOUT AUDIO CHANNELS

There are different types of audio channels, but there are 2 which are common:

A) STEREO (the standard)

B) Joint - Stereo

Stereo - This is what most MP3's use for quality. This mode creates 2 independent channels for both left and right. When stereo mode is used, you should also use a higher bitrate (160 or 192 kbits) - Stereo mode will allocate about half of this bitrate for each channel. In summary, for most audio, Joint Stereo at 128 or 160 kbps should be fine. If your audio is especially 'wide' and creates flange you should use 'Stereo' mode.

Joint Stereo - This mode takes advantage of the differences between the L+R channels. This allows more bits to be used in other areas and in many cases this can give an overall gain in encoding quality. Almost all encoders use joint stereo when encoding at 128 kbits. However, for some audio, Joint Stereo may create a 'flanging' or 'swishing' effect. In these cases it's better to use 'Stereo mode'

I just stick to the stereo. BUT....

If you listen to Trance or Dance music, then encode using Joint Stereo as this gives more good FX's to the tune. I listen to Trance and Dance music. A good example for this experiment is to use this song:

ANGELIC - Can't keep me silent.

If you encode this to stereo, the quality is great but in one "standard" or level. However, if you encode this song to Joint stereo then you will experience Stereo + some sound FX's and more "trance" music. It is hard explaining but try to get a hold of this song and experiment using different settings.

 

 

Hey.... You've been talking tooooo much crap that I don't need, get back to the DIVX encoding.......

 

Woops, sorry - I lost it there. (That is why I said you need patience at the start of the guide!)

Anyway, choose your MP3 audio settings and hit OK. Now click on the video codec button and a drop down box will appear. Choose the DIVX codec you wish to encode to, I chose fast motion:

 

Like I said before, I was happy with low motion and nandub doing a 2pass, but there were artifacts and some blocks, I did try to crop it but it didn't make it any better! So I used fast motion with these settings.

 

A BIT ABOUT LOW AND FAST MOTION CODECS:

 

Low motion - This codec is used mostly in every DVD rip. This is because it is much clearer at viewing DIVX videos. It gives ALOT of detail, nearly like DVD quality. But the codec will use a bit more file size but it is worth it at the end. You can predict the file size, especially when doing a 2pass!

If you set a bitrate of 950 in the low motion codec, then you are telling the video to use 950 bitrate. This is setting the "minimum" bitrate of the movie.

"This means that it will hardly ever go higher than what we set it. So if we set it to 800 kbps it would use 800 kbps on most scenes and only use a very little more or less depending on the action. This means the Low Motion codec is a lot more predictable." - Extracted from nicky guides on nicky.digital-digest.com

Low motion works well with low motion scenes, but sometimes you can get away with high action scenes

Fast Motion - This codec is used for high action scenes. Sometimes does not work well with low motion scenes but after encoding (from DVD, not capturing) with DVDx, it has proven it can work well in low motion scenes too. Fast motion is a hard codec to predict the file size, but is very low in file size than Low motion codec.

I took 2 DIVX DVD rip films:

Low motion = 685MB

Fast motion = 365MB

You have nearly halved the size using Fast motion

 

"When we set the Fast Motions bitrate we are setting the Maximim bitrate! This means it will always use an average bitrate of about 300 kbps, for example, until it reaches a high action scene and only then will it increase the bitrate to the maximum level! This is why people get confused, because it doesn't use the bitrate they put in until it finds an action scene!" - Extracted from nicky.digital-digest.com

 

There really is no way of finding out what the quality will be like using fast motion. I can assure you that it looks great after capturing (capturing > MPEG2 > MPEG2 > MPEG2 > DIVX 3.11alpha fast motion) but for DVD rips, there is no way to tell!

 

Can we PLEASE get back????

 

 We are nearly done. In the export settings, you may wish to change the resolution but quality may de-grade. You can Resize the video if you want, but make sure you select "Bilinear MMX" as it will give the best picture quality possible after resizing. You may wish to cut of the end credits to save space so that the conversion afterwards does not exceed the file size you would like it to be. The movie I have chosen, the credits start at frame number 134763. How did I find that out? Well, I loaded in the previous low motion conversions I did in virtualdub and find the frame number the credits began. You could also use GordianKnot to look at what frame the credits start at too. Some DVD software lets you look at the place where the credits are and gives you the frame number.

 You may also want to tell DVDx not to exceed a certain size when the conversion is happening. You just select the option from the drop down box in the "Volume dont' exceed" section. It is really all simple and self explanitry. We leave the rest alone.

Now click apply. and it will go to the main screen/preview screen.

Now, there is one button to click to do the conversion, HIT THE ENCODE BUTTON!!!!!!!!

 


How To Convert PAL (European) Video to NTSC (American) for VCD
 

 

Tools: TMPGEnc.

Launch TMPGEnc.

1. Press Browse to select the Video Source.


2. Change the directory to your CD / DVD Rom where the Pal VCD is inserted and the directory MPEGAV (For example F:\MPEG)




3. Select the file extensions to *.* and load the movie file. Often it is AVSEQ01.DAT but on some VCDs (With Intro etc.) it can be AVSEQ02.DAT or AVSEQ03.DAT

4. Press Open.

Note! If Tmpgenc says that the .dat file is a invalid file you can
try to change the settings in TMPGEnc under Option->Environmental settings->VFAPI plug-in and right click on the DirectShow Multimedia File Reader and increase the priority to 1 or 2 and try open the video again.
or convert the VCD dat to a MPG that you should be able open, read.


5. In the TMPGEnc window you should now see the first frame of your VCD.


6. Press load and open the file
VideoCD (NTSC).mcf which is in the Templates dir of TMPGEnc.


7. After pressing Start TMPGEnc should encode your movie


DVD Ripping Programs You Should Get Now
 

 

RIPPERS / DECRYPTERS
These programs will convert your store-bought movie files into video files on your PC, and will also strip off the CSS copy protection.

DVD Decrypter: A simple tool for moving video to your hard drive, with a minimum set of options.

Smart Ripper: Another decrypter with a lot more options. Somewhat confusing to use, but it produces good results.

CladDVD.net: Works on top of Microsoft's dotNet framework, it's pretty easy to use.


ENCODERS
Don't want to make a perfect DVD copy? Want to reduce the size of your DVD movie to fit on either a single recordable DVD, or to the SVCD, VCD or DivX formats for playback on CDR or your PC? These tools will help you – but don't expect a lot of hand-holding

FlaskMPEG: A great way to create VCD or SVCD files. Lots of options, somewhat confusing.

DVDx: Many people like this product for converting DVDs to VCD, SVCD or DivX.

Xmpeg: My friends in the video business all swear by Xmpeg. It will convert to DivX, VCD, SVCD and DVD video formats. It even includes wizards to make things easier for you.


ALL IN ONE
These bundle everything together for one-button copying and conversion. There's only one, though, that I can recommend

DVD2SVCD: This one bundles lots of programs together and tries to do it all. It's a bit tough to configure initially, and the options can be confusing. Still, it's a good place to start if you're looking for one-button ripping, decrypting and conversion.


FINDING THESE PROGRAMS
They can usually easy be found on P2P sharing programs like Kazaa or WinMX or just try entering their names in google or altavista.  Most of these programs are freeware as well!



DVD Basics
 

 

DVD movies, like music CDs, are stored digitally on that plastic disc, in a stream of zeroes and ones almost as long as War and Peace and Remembrance of Things Past combined. VCR and cassette recorders, by contrast, transcribe in an analog format –closer to what your eye and ear perceive.

Each time a cassette or VHS tape is copied, the music or video degrades. That's because the recording can't match the original source. That's why the "master" was so important in the pre-digital days, because only it could generate the best copies for sale or share.

But when you make a copy of a digital file – whether it's a Rolling Stones song, Harry Potter movie or Excel spreadsheet – the copy is identical to the original. It's hard to mess up ones and zeros.

When Hollywood decided on a digital movie format – called DVDs – it decided to protect it with something called CSS, or the Content Scrambling System. Like Pig Latin – ere-whay vree- ay erd-way is-ay anslated-tray to-inay nother-ay (where every word is translated into another) – the ones and zeroes stored on a DVD are unintelligible garbage unless you have the key.

That key was jealously guarded, but like most secrets, it got out. This was first done in a breakthrough program for DeCSS which laid the groundwork for what we are talking about here.  Now anyone with a computer and DVD drive can easily strip off CSS in a process called "decrypting", and create a perfect copy of a DVD's video and audio content on a hard drive. And from there it's easy to create a DVD copy that's identical to the original.
