Curious about XviD/DivX Color Compared to MPEG-2 Color

How do you compare colour? If you're watching DVDs on software DVD players, they all have some extra saturation added. Look for picture profiles or something like that. XviD doesn't "mute" the colour just like it doesn't make picture darker. It sounds like a difference in playback only.

MeGUI and the other primary x264 frontends need .net 1 or 2, but x264 itself only needs an ia32/x64 platform and avisynth. You should be able to use virtualdub vfw, SUPER, or Mkvmagic, but I don't think any of them expose all the features of the command-line. Bummer about the SP2 business. Otherwise rogerwilco's probably got the right idea, plus there's always ffdshow's color/gamma tweaks.

@kalorx Hi! If you've not already done so, you might try the following as an experiment, to narrow down the source of the difference you're seeing: Make an .AVI (DivX or XviD compressed) from a commercial DVD that you own. Play a specific portion of the DVD with a software DVD player (VLC, WinDVD, PowerDVD, or similar). Then play the same portion of the .AVI with the same player - to see if there is still an observable difference in richness of color...

how to know when to use colormatrix in megui?

Colormatrix() should be your first filter, directly after mpeg2source("..."), so it can autodetect what (if any) transformation is necessary. I don't know how this is handled in MeGUI-generated scripts, though. Better check it out.

Where in DGIndex does it report the colorimetry? I've been looking, but I can't find it...

Thanks. I'm apparently using an out-of-date version of DGIndex...
