Contrast/Brightness editing for .WMV video files

[ralphjuden]

I have a logitech webcam that records video in 720p, it saves my files directly to HD in .WMV format. I'm looking for a program that simply will let me do some contrast/brightness enhancing but with good quality (like photoshop for pictures). It seems to be difficult finding something that supports .wmv, and I have already wasted some time downloading programs that don't support it, then I had to chase around conversion programs, then chase all the missing codecs they didn't have. Figured you guys would know which one program would work for me. Thanks in advance.

Free solutions:

Have your tried windows media encoder and Microsoft Expression Encoder?

You could try virtuldub (with the wmv plugin) or avidemux. The have contranst/brightness filters. But they can't output wmv directly, use instead h264 or divx/xvid codecs in a mp4 or avi container.

Tried AviDemux and all I see is the following when I import the vid and press play.

WMEncoder didn't really do anything at all but convert files around which I don't care about. I don't care what my output file is, as lon as the video doesn't lose massive quality from over compression or something. I just want to be able to input the video, make some minor changes, then export. What am i doing wrong

upload a small sample,.. (only a few seconds is enough) normally AviDemux (and other lavcodec based tools) should handle wmv 720p fine,...

your sample works fine in the 2.5.x branch

try older version (not 2.6.x branch)

the one I used was 2.5.6-1

it's progressive and definitely a bug in AviDemux, tested with mplayer and other lavcodec based tools and Avisynth+FFmpegSource2, all worked fine.
(poisondeathray was faster)
