>>92572643also to split MP4s use software called "Handbrake", then under "Range" menu change it to "Seconds", then add the start and finish timestamps. So if you have a 2.5 hour movie and want to split it in half, do "00:00:00 - 01:15:00", encode that half as one split. Then do a second encode as "01:15:00 - 02:30:00".
