Is there any interested a free mp4 joiner tool only, that does not need to re-encode first ? Used iMovie before to do this, but it re-encodes, and i hate the aspect ratio it uses... It may be standard to iMovie, but its not standard to the original file. Mp4 Joiner works somewhat, but strips the audio out. Tried cat tool under Terminal, which doesn't work.. Any simple joiners out there that is free, and doesn't re-encode? I have around 60 mp4, each 7 minutes long but wish to combine then into one 1 hour file. SInce i'll be encoding them with Handbrake anyway for AppleTV Preset it doesn't make sense to re-encode them just to join.
