I have trimmed or cut portions off of several different .m4v and .mp4 videos, yet when I load them onto my iPod Classic the cut portions are still there! These portions do not appear when I play the videos in Quicktime, iTunes, iMovie, or any other video program I have tried. Not only does the edited footage remain, but the video part plays at a super fast speed while the audio plays at normal speed and reflects the editing I have done on the clip. Once the video catches up to the audio, everything plays in sync at the proper speed. I have tried this with several different video clips now and I get the same result each time. - I have used Quicktime to edit them as well as MPEG Streamclip. - I have tried trimming the original clip and doing a "Save As" - I have tried cutting the footage I want to keep from the original clip and pasting it into a new clip. The only way I can get the video to play normally in the iPod Classic is to reconvert it in iTunes to an iPod compatible video, but this recompression process results in terrible video quality. Has anyone dealt with this and found a solution for it?
