What does video crop top bottom left right do?
In the header editor, there are commands to video crop top, bottom, left or right. What exactly does this do? I can take a music video with video noise or old video that has the timing signal at the top. Issuing a crop top command does nothing. A youtube video with perhaps 2 pixels of noise at the top, Maroon 5 - Moves Like Jagger A youtube video with 4 pixels or so video timing noise issue, Def Leppard Pour Some Sugar On Me (Official Video) In both cases, I can issue a crop top command of the entire video height and still nothing.
