Hey All My Samsung camcorder (model escapes me, (1080i)) records in .mp4 format but iMovie (all versions) struggle to play the video smoothly (using video skimming) so I'm sure I need to convert it to a more friendly format. Anyone got any suggestions? I've got MPEG Streamclip so some ideal settings would useful! I'm after no quality loss, so size is irrelevant. Thanks.
