View Full Version : DVD to RAW Avi?

I know that DVD Vob files are already compressed to MPEG 2 format from the source. What I need is to convert VOB files (MPEG 2) and convert it to RAW AVI . I need it to be RAW AVI to be able to edit videos and convert it to any format. Any suggestions? :stupid:

Hi!

If by "Raw" .AVI you simply mean Uncompressed .AVI, just load the .VOB into VirtualDubMOD and leave the "Video" at its default setting of "Uncompressed RGB" - and save with a new filename...

I tried doing that but the video came out really steppy.

Please define "steppy".

Are you talking about the playback "looking like a slide show" (which may be the result of an inadequate system) or do you mean that you are somehow dropping frames as a result of the conversion? - or yet something else?

It's like a slide show. I'm running a dual Xeon processor at 3.2Ghz with 3 gigs of ram. With Windows XP. Also had issues with Audio & Video sync.

Then, as long as you haven't dropped any frames, you shopuld be able to perform your editing and conversion/compression.

If this isn't feasible, you can use VirtualDub with a "lossless" codec, such as HuffyUV...

That's because uncompressed RGB has a data rate that is larger than your hard disk can support when playing it back. Try saving to a compressed format such as XviD.

That's a good point. Maybe if I upgrade the video card, playback would be a lot better? I can't encode the video either xvid, divx, H.264, etc.., because we use Avid system to edit the video's or use a Mac, and at times it won't read it or have compatiblility issues when we try to move this media to another system. That's why I'm going the AVI route. :helpful:

No. The problem isn't with your video card, it's with the maximum data transfer rate of the hard drive.

That's why I'm going the AVI route. Uncompressed RGB is fine as an intermediate format for exchange, editing, etc. Just don't expect to be able to play it back smoothly. After all the editing, etc., is done, you'll presumably render it to a format that can be played.

So just re-use VirtualDubMod then? Thanx for the help guys/gals.

Yes - As I said, Then, as long as you haven't dropped any frames, you should be able to perform your editing and conversion/compression...

Is there software out there, to test the converted AVI files have dropped frames?

If you've done a conversion to "Uncompressed RGB .AVI, you shouldn't have any dropped frames...

Check the original files frame count and then check the resulting avi's framecount. Though there is no reason why frames should be dropped during encoding - except for telecined material where the MPEG decoder might remove the telecining though I dont know how VDubMod deals with RFF flags.

For a good reason, the most popular way for transcoding DVDs is the DGIndex --> AviSynth method. Uncompressed RGB is a very unreasonable format.

If you want to edit the original content before transcoding, reconsider the suggestion to use a _lossless_ codec like huffyuv. Much easier to edit, much more reasonable filesize, no quality loss at all. But I don't really see an advantage over using DGIndex/AviSynth.

So, DGIndex is available with the AviSynth bundle? And where can I get the huffyuv codec? Sorry for being such a noob at this stuff.

You can get it all here; click 'download' in the menu, then click on 'full software page'.
