I think you know what I'm talking about - when you mix frame rates on a timeline, everything isn't always "cut" right on the frame - which you can fix manually by grabbing the edge of the clip and snapping it to the proper cut line.
My question is this: is there a script that will fix instances of this - clips not "starting or ending" on a precise frame?
Also - would that kind of an issue (if one clip was overlapping the other) cause something to look like a double frame in QC?
