I'm getting ready for my encode and was going to set the border color to the minimum black level in my captures. As a quick check, I ran ColorYUV and it reported back that the minimum Y was 5 and a max of 255 If I place the ColorYUV function prior to the resize, I get a Y min of 14 and a max of 253 for the same frame of my movie. It did not matter if the color space was YUY2 or YV12. Is this a bug?

Oh, ya specifics:
Avisynth 2.5.5 (latest release version)
AthlonXP
XP OS

Resampling changes the values of your material. This is why ringing happends on sharp resizers, etc. PointResize and Bilinear should not modify your color range.
