DVD2AVI finishes too quickly!

[Toge]

Probably a newbie question. I'm a school at the moment so I can't describe the settings I'm using to encoding my VOB>AVI, but I can say that when I select SAVE AVI and select No Recompression.

Whats going on?

IIRC DVD2AVI can't create anything but standard AVI files, i.e. no OpenDML files, which means that the maximum filesize is 2GB. With 'no recompression' selected each frame requires (assuming PAL, similar calc for NTSC) 720x576=414720 pixels, each using 3 bytes of data in RGB mode => 1244160 bytes/frame. Each second of video have 25 frames => 31104000 ~= 31MB/second. Thus 2GB => ~69 seconds of video. That I'd say qualifies as finishes too quickly.

[Toge]

yeah, but the file i get from the output is 0KB

[hakko504]

Anything is possible of course, including the possibility that Windows reports the filesize as 0kb even though the file is much larger simply because the file isn't properly closed by DVD2AVI.
And another thing: You are quite sure you have NTFS discs? Once in a while people with Win XP/2k have FAT discs because of a bad installation or because they upgraded from 9x/ME without reformatting the HD's.

In any case, if you want more help then you need to give us more info: describe (in detail) exactly what you are trying to do, what settings you use (including version of DVD2AVI) and what the result becomes. And I assume you have read the DVD2AVI FAQ (http://forum.doom9.org/showthread.php?s=&threadid=59272)

Why are you using No Recompression?

This would just copy the Mpeg2 compressed
video stream from the vob container to
an avi container.

@ hakko504
you're mixing something up.
No recompression is not the same as the
uncompressed RGB codec.

I think (normally) it's not possible to
create Avi files with an Mpeg2 videostream.
So that's why DVD2AVI stops immediately
and creates 0 byte files.


When you're trying to compress vob files
to another format (like divx) you have to
choose another codec!

Right.

So what if we are having that problem. what can i use to get my d2v into AVI. i know that it was in mpeg2 stream because, when i was saving the file, i was looking for a d2v option but all i could find was a m2v option. but when i saved, it saved to d2v anyways which was weird but i wanted it to be d2v not m2v so i'm not complaining.

but, the problem arises now and i think it is the same problem as Toge. I loaded the vob, saved the file, and wanted to save the avi. but when i get to the step where i have to choose the compression options, if i choose DivX, its done in a millisecond while if i choose mpeg, i get the windows error message saying "bla bla bla program has encountered an error and needs to close." whats going on now? DVD2AVI worked earlier. why is it doing it now? and what can i do to fix it?

thanks,
TC

i am getting the exact same problem. Is this the proper program to convert .vob files to .avi files. I tried to use virtualdub mod but i get corrupt .avi files that dont play properly. Any help??????????????????????

[jggimi]

Troy, most DVD2AVI users are creating .d2v project files, not encoding AVI.

To go from .vob to .avi, you should be following one of Doom9's many step-by-step Guides (http://www.doom9.org/divx-encoding.htm).

[troy]

I do not want a divx file. I want a simple 720 x 480 avi file that I can import into premiere to mix with my camcorder video????

[hakko504]

@troy

AviSynth and/or vfApi is what you need.

Create a D2V with DVD2AVI and open it in vfApi or AviSynth and then import the fake AVI from either app in premiere. Check the guides jggimi pointed you to, the'll give you a push in the right direction.

[jggimi]

Troy and Toge both may benefit from frameserving. Hakko is correct that one of the guides may help. But some additional guidance may be helpful. Use one of the DVD2AVIs suitable for saving .d2v projects for frameserving (1.76 or dg version).
Use the matching MPEG2DECxx.DLL version with AviSynth.
Use AviSynth as input to the rest of your processes.
The guides are designed to take you all the way to finished products (MPEG-4 / AVI). But you need not go that far. Gordian Knot uses .d2v projects as input, and AviSynth scripts in interim steps. I recommend using Gordian Knot, but as an AviSynth script generator, which means using the "Save" rather than the "Save and Encode" button. The current releases uses DVD2AVIdg and it's matching mpeg2dec3dg.dll.
