Cropping video for later use in Jitter

August 16, 2006 | 11:07 pm

This isn’t really a jitter question, more a QT or Final cut one perhaps. I want to generate two streams of video 320 x 480 that I can recombine onto one screen in the final jitter patch. How do I take a DV capture that is 720×480 and cut 1/2 of it away so that I can use it? I am planning to film to one side of the display so that I can cut the other side off.

Thanks,
Paul Litherland

AFAIK, this is kind of annoying to do in FCP, though perhaps there’s
some way to use scripting to your advantage. Otherwise you need to
create an FCP project at the output resolution and place your footage
(with correct offset/scaling) in the timeline and then export.

If you have jitter, I might suggest a simple batch processing
framedump of the movies from jit.qt.movie through a crop (jit.matrix
srcdim/dstdim) + to jit.qt.record.
