Measuring the luminance of mp4

[banaguitar]

Hi,

I am trying to convert 16-235 and 0-255 avi test streams to mp4 with XMedia Recode and Hybrid, but I don't get the exact RGB values for black and white. I use the tool CaptCouleur 2.1 to measure the luminance on VLC Player.

Here are my settings for Xmedia Recode:

Here are the avi test streams with black and white areas. You can check. They both have correct RGB values.

What's wrong with conversion to mp4?

Thanks for help!
