I must be going aout this all wrong. All I want is to find a program that will edit .mp4 files. I have 2 commands I'm looking to perform - split and merge. I've tried 4 different pieces of software, and they are either ridiculously unintuitive or they transcode the file to a different format (iMovie). Basically I have an .mp4 of my band playing a gig. It's an hour long, and it's SD resolution. I just want to chop up the video into the individual songs. I want the 15 or so individual clips to in .mp4 when I'm done - no fancy transitions, just cut to length. I'd also like the ability to merge 2 .mp4 files together into a single file - like using cat on two files in the terminal. Is this too much to ask? There SHOULD be a program that does this relatively simply. Of the 4 I've tried, none were simple enough for me to figure out, had horrible bugs, and I'm not patient enough to let iMovie encode the whole thing twice. I'm very tempted to write my own app. That seems easier that figuring this out. I am just suuuuuuuuuper frustrated right now - I'm hoping the collective minds at MacRumors could help me sort this all out. I'v tried iMovie, Simple Movie x, Vivideo, Quicktime (apparently QT 7 Pro was awesome, and then Apple killed it? The version I have does nothing in terms of editing). What am I missing?
