Just to verify, if you encode in RGB24 or YUY2, and play the .avi and the resulting .wmv file, the .wmv file appears brighter than its source avi file?

The two files I am using were created from VirtualDub - one saved as RGB24 and the other saved as YCbCr 4:2:2 (YUY2).
The encoding works fine. Its just that the output video that is shown is noticeably brighter.

Wow, that's a blast from the past! I now work for Microsoft.
Can you tell me which AVI codecs you tried for RGB and YUV?

I am new to the Windows Media Encoder 9 Series. I had the same problem as=
the attached message below from 3+ years ago mentioned, i.e. the encoder =
produces images that are brighter than the source images and color isn't =
preserved perfectly (even at high bitrates). I have tried this with AVI =
files in both RGB and YUV formats.
- Is this a feature/bug with the encoder?
- is this a problem with my settings?
