I just tried to use QuickTime to trim mp4 video clips, after trimming I can expoted video clips to iTune or
other folders. Somehow my quicktime could not play mpeg video directly, so I need to user other software (
Wondershare video conveter) to first convert mpeg video to mp4 format, then use QuickTime to trim mp4 video clips.
Hope this may help
