    Identifying an a codec in .mp4?
    Hi All.

    What I'm using:
    MacBook Pro early 2011 (16gb RAM, 2.3 GHz, Intel Core i5)
    OS X 10.9.3
    Final Cut Pro 10.1.1

    Camera: Sony AX-100 4K
    Codec: XVAC-S

    I'm fairly new to editing video and have two questions:
    1. How do I find out what codec the .mp4 was shot in once it's on my Mac?
    [sometimes I shoot in a different in codec and would like to be able to figure out the codecs once, once they're on my computer]

    2. If shooting in 4K, will I always need to edit in proxy with the current hardware I'm working with?

    Any other unsolicited advice from experience is much appreciated. Cheers!

    Open it up in Quicktime or VLC. use the command I shortcut and the info window will tell you what codecs are in that file
