Clip Intermittently Jumping to Later Frames
I am working on a video, and I have one clip that is doing something strange: The clip will randomly insert a frame (or several between current frames) from later in the clip. This only happens when the clip is on the timeline, not in the viewer. And even then, it only shows up sometimes when I am scrubbing through or when I go frame-by-frame, but it ALWAYS shows up in the export. I change little things to try to get rid of it and the problem changes without any apparent pattern (more frames jumping, closer together, etc). Any idea on what to do? I have already tried to pull a new version of the clip, but the same thing happens. Here is a clip of the export.
Just for the record, the first transition is a separate composite shot, the problem clip is not part of that comp.
