I opened a MP4 in Quicktime X to trim and split and delete segments..that goes fine, but I can't export it back to mp4...or close it and save the edited file back to itself, or use "Save As"...all I can do is save the edited file to a .mov, which i'm losing the 5.1 sound track..they become stereo.
Does Quicktime not do this? I've done this kind of thing before...did I use something else?
