Howto Rip a small clip: DVD to Xvid

[porjo]

This howto will show you how to grab a small clip from your favourite DVD and save it as a compressed AVI file with Xvid compression for the video and MP3 compression for the audio.

Tools Required

[*]DVDDecrypter - http://www.doom9.org/software.htm. This is used to rip the raw audio & video from the DVD disc to your hard disk.
[*]AC3 - ACM Codec - http://fcchandler.home.comcast.net/AC3ACM/. This is required in order for Windows to play back the AC3 encoded audio. Some systems may already have an alternate AC3 codec installed from another 3rd party app. If you're unsure, then you probably should install this.
[*]Auto Gordian Knot - http://www.autogk.me.uk/. This is used to compress your video clip down to a much smaller size by converting the MPEG2 video stream to Xvid and the AC3 audio stream to MP3 format.
[/list] The Xvid codec & VirtualDubMod are also required and are bundled with the Auto Gordian Knot package.

What to Do

1. Install the software
   
   
   
   DVDDecrypter & AutoGN have their own install scripts. AC3-ACM Codec is installed by unzipping the files to a folder somewhere, then right-clicking on the ac3acm.inf file and selecting 'install'.
   
   

[*]Run DVD Decrypter







[*]Select 'Mode'->'IFO'
[*]Uncheck all the chapters except the one containing the scene you want to rip
[*]Select a destination folder for the ripped files
[*]Click the decrypt icon.
[/list]
[*]Run VirtualDubMod - select the clip and save in AVI format.


VirtualDubMod is bundled with the Auto Gordian Knot package. Locate the install directory for AutoGK, and you'll see a subdir called 'VDubmod' - run the file 'VirtualDubMod.exe'








[*]Go 'File'->'Open video file...'. Select the .VOB file you created earlier
[*]Now select the portion of the video you want:


[*]Move the slider along the bottom to the beginning of the part you want. Click the left book-end icon (second button from the right on the bottom toolbar).
[*]Move the slider to the end of the part you want. Click the right book-end icon.
[/list] [*]Save the clip. Go 'File'->'Save As...'. Select a file name and click 'Save'.
[/list]


If there are multiple parts that you'd like to string together, you can repeat the steps above to generate multiple AVI files. When you have all the sub-clips ready, run VirtualDubMod again. This time open the first clip, then select 'File'->'Append segment...' to add the remaining clips onto the end of the first clip. Finally, go 'File'->'Save as...' to create the final joined clip.


[*]Run Auto Gordian Knot






[*]Click the folder icon next to the 'Input File' line and select the final AVI clip you created above.
[*]Leave the Output size on the default. The clip will not actually be '1400Mb' in size this is just a quality scale! - the higher the size of the output, the higher the quality of the video will be.
[*]Click 'Add Job' then 'Start'
[*]Sit back and relax while your video is compressed down - it can take awhile!
[/list] [/list]


When the job is done, you should have a new AVI file with '_agk' in the filename. That is the finished product. The other files generated along the way are not required and can be deleted.

Hmmm ... not a bad guide


Some comments:

1) It would appear that you are outputting from virtualdubmod into uncompressed AVI, since you don't mention anything about compression. One had better hope that this clip does not have too much length to it or alternatively that the user has a shitload of free hard drive space !

2) https://www.videohelp.com/guides.php?guideid=625#625
Pretty much does exactly what your guide does, but IMHO a lot cleaner and quicker since you do the editing and encoding in the one program without having to save out to an intermediate file.

Hi-

Leave the Output size on the default. The clip will not actually be '1400Mb' in size this is just a quality scale! - the higher the size of the output, the higher the quality of the video will be.

Not exactly. If you have a short clip, say 2 minutes long, whether you set the output size for 100 MB, 1 CD, or 2 CD, it'll reach max quality and size long before it reaches any of those output sizes. That is, it'll reach a certain size and will no longer be able to get any larger or get any better. It will have "saturated the codec".

And you're still running 2 passes. Since you seem to be recommending max quality and size, better might be to set it for Target Quality and 100%, which will then run only one pass, and get you results in nearly half the time.

And, as Jim said, there's not much point in saving as an uncompressed AVI, as the filesize will be huge. Better might be just to cut the Vob into a smaller piece using MPEG2Cut or some such, and then open that in AutoGK. You won't be able to edit, as you described, but if someone doesn't want to edit and join, he won't need to do that. And even if he does, better (and smaller in size) might be to use a lossless codec, like HuffYUV or Lagarith.

Either that or encode the entire chapter(s) in AutoGK at Target Quality 100% then optionally use vdubmod for editing afterwards, so that Direct Stream Copy can be used.
