  • Canon 7D 24p footage sync problem

    Hey,

    We shoot some interviews with canon 7D in 24p mode. We recorded the audio in an external mixer with 24fps frame rate. Now I notice that the 7D footage is actualy in 23.98 and in the long shoots it go out of sync, does anyone know why is that happening what am I doing wrong?

    What happens:
    You shot video @ 24 fps. Now you play back as 23.976 fps.
    That is a different speed. So if you don’t compensate, you’ll loose sync.
    As mentioned in a thread just below this one:
    Restamp the audio files as 48.048 Khz. Then FCP will not use the new sampling rate, but just change duration and you’re sync again.

    There are a lot of (free) utils out there that can do this.
