Visual Difference b/w ogg and avi

[lar1r]

Has someone else tried this.

Encode a clip with DIVX 4.12 with wave audio.
Make an avi and compress the audio to MS Audio V2.
Make an ogg and compress the audio to Vorbis Ogg.

Does your ogg movie appear noticeably darker and have saturated colors?

Is this normal? The video was done in DIVX4, and I have noticable differences. I don't understand since the video is the same source.

If someone knows how I can capture an ogg snapshot - let me know. ( the avi snapshot is fine)

What do you mean when you say "Make an ogg" and "your ogg movie" ?
How does it differ from regular DivX ? I thought the only difference is in audio.

I will ask Tobias to have alook at your thread ... what you describe could be a small bug in his DirectShowFilter ... i cant see any other reason.

One more thing : If you try to play the movie in PowerDivX player or BS player, what filters will be in the filter list ? What video renderer will be used and are all overlay settings in the renderer the same ?

Maybe it was just Media Player 6, since B-Player makes them look the same.

I think the settings in the divx decoder are just represented a little different (even though the global Divx values are the same in the avi and ogg).

Interesting Note:
The avi and ogg have different video time stamps (even though the same video). example: position at 9:03 in ogg is position 9:07 in avi. But the movie lengths are reported the same.

this problem with time stamps could be a seeking a bug. E.g. I once watched a file from the beginning to the end -> no problem everything was fine. But then I seek aroud in the file and watched the end again: the shown differed 2 secs from the time that was shown before. ( the file has a length of about 43mins, VCD resolution ( NTSC ), encoded with XviD )
