Anti-aliasing does not work

No matter how blurry or sharp my footage is. After using proteus to fix it it looks amazing. But the issue is that there is alot of aliasing which i cannot get rid off. Tried for hours.

also Anti aliasing does not seem to do anything when put to -100. Or anywhere in the middle. how come do i have this and is it from the latest update?, Renders seem longer when added anti aliasing but footage is rhe same
