I've used the 3d Camera Tracker in AE numerous times, and it usually works out great. Just recently I switched to trying out PFTrack just to see how much more I can do with a more professional software. I'm not sure how to correctly configure PFTrack for my camera, as far as the "film back" goes...
This is the camera info for the camera I have here at work.
1/3-inch HD CMOS Pro
Focal Length: 4.25-42.5mm (35mm equivalent 30.4-304mm)
I know I also have to probably take into account the whole rolling shutter issue with the CMOS sensor... but I'm unsure of what information I must input for the "film back".
