Encoding white frames

[Haya]

Hi

I'm trying to encode a movie, made from a bmp with avisynth with the following script:
clip1=ImageSource("c:\1.bmp", end=125,fps=25)
clip3=ImageSource("c:\movie\2.bmp", end=125,fps=25)
clip2=ImageSource("c:\movie\3.bmp", end=125,fps=25)
clip4=ImageSource("c:\movie\4.bmp", end=125,fps=25)
clip5=ImageSource("c:\movie\5.bmp", end=125,fps=25)
clip6=ImageSource("c:\movie\6.bmp", end=125,fps=25)
logo=ImageSource("c:\movie\logo.bmp", end=100,fps=25)
logo=AddBorders(logo,0,50,0,50,$ffffff)
clipfinal=dissolve(clip1, logo,25)
clipfinal=dissolve(clipfinal, clip2,25)
clipfinal=dissolve(clipfinal, logo,25)
clipfinal=dissolve(clipfinal, clip3,25)
clipfinal=dissolve(clipfinal, logo,25)
clipfinal=dissolve(clipfinal, clip4,25)
clipfinal=dissolve(clipfinal, logo,25)
clipfinal=dissolve(clipfinal, clip5,25)
clipfinal=dissolve(clipfinal, logo,25)
clipfinal=dissolve(clipfinal, clip6,25)
clipfinal=dissolve(clipfinal, logo,25)
return clipfinal
Each bmp contains very much pure white (#FFFFFF).
When i open avs file in vdub it looks just fine but after encoding
all white is turned into gray.
I am using a 2pass encoding and Nic's XviD binaries XVID - 06/04/05

How "gray" do you mean? 50%?

Exactly, 50% gray where it should be pure white $FFFFFF !

Are you sure it isn't a problem with your video renderer?

Make a screenshot of the output, and check what the exact colors of the pixels are. They'll probably be around 235-240 if this is the problem.
