Re: [Avid-L2] AMA sync issues

Also movies from I-phones have variable frame rates as the camera adjusts
the frame rate depending on available light. Work around is to open Iphone
movies in Imovie which knows how to extrapolate the fps into a constant
2997. Then AMA them in as quicktimes. Sure this has nothing to do with the
pro res problem. filmicpro.com offers an Iphone ap that can set constant
frame rates, looks like all progressive, no interlaced, but who cares,
you're always delivering progressive anyways, right?
