View Full Version : VirtualDub and uncompressed (RLE?) AVI

I'm using an emulator for the atari 2600 (pcaewin) that has an option for saving to AVI.

The resulting files are uncompressed AVI that VD can't handle for some reason.

VD gives the following:
"VideoSourceAVI: uncompressed frame 0 is short (expected 80000 bytes, got 4614)"

file information states that it's "uncompressed rgb8"
Gspot list the codec as:
RLE (_RGB)

Media info list the codec as:
"RLE RGB with arbitrary sample packing within a pixel"

The files play fine in any media player.

I've tried VFW part of FFDSHOW to enable/disable RLE, still the same.

Tried many version of VD/VDMOD - all the same.

Also cutting it and saving with direct stream copy and loading the resulting file gives the same result.

I uploaded a sample file here:

If it helps.

Thanks.

Hi!

1) Load the file into "TMPGEnc"
2) Set to "MPEG-1"
3) Change vertical resolution from 250 to 240
4) Save as ".M1V"
5) Load ".M1V" file into VirtualDub
6) Select desired codec for compression (e.g. DivX, XviD, etc.) and save as .AVI

(The Space Invaders are still cute - after all these years!)

Thanks, it works. :)
I think I'll go with MPEG2 as not to lose much quality in the process.

Any idea why VD can't handle this directly?

Any idea why VD can't handle this directly?It seems to be related to the color format...
