Thanks for testing!

Also, they do not "obey" my given output-levels (0-255, 16-235 or wathever). So I need something to produce a nice equal (given) lumi-level like the screenshot in my previous post and without clipping.
Your autogain filter already comes near to that but with mode=1 I have to put some "brake" on the video (adding a small 4px white border) to reduce the gain-effect on the whites
You can now try AutoGain(adjust_mode=1,dark_exclude=0.00,bright_exclude=0.00)
