I have two videos (A.MOV and B.MOV), that are supposed to be perfectly synced. However, Video A (3708 frames), has 5 more frames than Video B (3703 frames). When I look at the timestamps of these frames, the extra A frames are at the very end of the video. In addition, the last frame in each video is a “padded” frame, with a duration much longer (around 10 times) than that of the other frames.
