    What does the 64 bit times checkbox do? And Should I save as a movie or video? Only difference I noticed was that with video it puts the extension as m4v while movie is mp4.

    It's for files bigger than the 32bit limit of 4gb. If you have any videos you want to transmux that are bigger than 4gb turn this on otherwise you will end up with a corrupt file being output.

    "Why can't I mux file larger than 4GB?
    You need to enable the "64 Bit chunk offset" checkbox if you think the files will be bigger than 4GB. It's not enabled by default, because many devices (old iPod, Playstation 3) can't read this type of mp4.

    It means track length and durations are stored in a 64bit integer. The usefulness? For example if you have an audio track longer than a day, 32bit runs out at about 24 hours for a normal aac or pcm track.

    This is what I was inquiring about. I already understood the 4gb limit and the 64bit chunk offset but no one ever talks about the 64 bit timecode. Thanks all!
