Why divx-files through Avisynth are blue?

[Valky]

Why is my picture very blue when I try to test some noise filters in avisynth with div3 or div5 files?

Movie is very blue in vdubmod and mpc if I open avs-file with them. Xvid-files look normal and some of my tv-captured avi's too (codecs huffy or picvideo).

So this is only related to divx-files. Anybody now what's wrong here?

You haven't posted your script, nor your release of AviSynth, so there's little we can do but make guesses -- such as a bad DivX Decoder install, or some sort of colorspace issue.

I've previously reported a problem to the AviSynth development team regarding recursive opening of YV12 AVIs with Version 2.53. Does this match your problem?

Actually it doesn't matter what script.

Just plain 'Avisource' command gives me this blue screen. And I don't mean that the whole picture is blue. Movie plays fine but colors are wrong. Picture seems to be too blue. 'Avisource' works with xvid-files. Also if I use 'Directshowsource' command, then also Divx-files shows correctly.
I have only divx, xvid and latest ffdshow-decoders installed.
My avisynth is version 2.5.2.0


I guess screenshots tells more than I can describe:

I guess you can notice the difference :)

Please extract a few frames into an .avi, using Vdubmod in Direct Stream Copy mode, and post a link to the file.

Interested forum members could then attempt to duplicate your problem.

Hi-

Try adding SwapUV() (http://www.avisynth.org/index.php?page=Swap) to your scripts.

Yes, this works!
Thank you. Don't know what it did, but it works :)
