I'm trying to do some motion tracking for a music video with boujou4 and I can't get the film back size (size of the cdd in mm) right for HVX-200 that my footage was shot with. I've looked all over and Barry Green posted somewhere that it was roughly 5.24 mm by 2.95. Has anyone had any expierence with this or does anyone have a real answer from panasonic?
The process that I use with SynthEyes is to first get my HVX200 footage in to Shake and resize it to 1280 x 720 (which is what I shoot at). Then I apply the lens node to undistorted the image. I shot my garage door that had a bunch of lines on it so I know how much to undistorted the image to make it flat.
Render that out as a self-contained QT movie for SynthEyes. The back plate comes in as a default 24.892mm x 14.002mm.
Since 3d programs, that I know of, don't render with lens distortion I undistorted it first and then add it back in when I do my final composite.
