Thanks a lot Didée.
I tried all functions. Every of them works except "antialias()".
"ediaa()" & "saa()" give me the best results.
Unfortunately, I still have a bit of aliasing.
Does it possible to make antialiasing filter works stronger ?
( Maybe it could make my video blurrer but anyway I want to try and I'll take a decision later. )
Sorry if I ask stupid questions.
