PF Track help
Posted in: Matchmoving SoftwareHey guys,
I’m doing a 3D track in PFTrack for a big problem shot. It was shot on green screen with track markers but the camera movement is a huge sweeping rotation of over 100 degrees. I thought I got a pretty decent track all things considiring as I was able to place test objects in and they stuck great… But the grid in the rotation is actually not rotating nearly enough. So what I end up having is a first have that tracks well a rotation that is wrong and a second half that tracks well.

Everywhere I read up says to use user tracks to fix problem shots but I just don’t understand how they work… Do you use them in conjunction with an autotrack and if so when? before the auto track? or after? Also What should I do when the track marker goes off camera? Just move it off frame and make new tracks?
