I'm a so freaking pissed. I've been trying to convert a 720p MKV video file to a 720p MP4 file with NO video quality loss. I've been trying to do this for ALMOST A WEEK with no luck. All these threads go on about "demux" then you "remux" then you whatever "mux" ughhh!! I have no idea what any of that means. They then go on about having to do some crazy stuff in terminal with a program called MP4Box, I have no idea what that does or how to use it, what so ever. Instead of spending weeks on trying to convert these damn 720p video files, isn't there a program that I can just drag the file onto, set it to MP4 and get my file with no quality loss?!?! PLEASE HELP ME SOMEONE, THIS IS DRIVING ME FREAKING INSANE.
