[PFTrack] - Manually specifying focal length in certain frames?


#1

I have a video clip with a variable focal length, and I’m struggling to get a good solve. The camera motion is all right, but PFTrack has issues getting the focal length correctly. I have known focal lengths for the first and last frames, but not for everything else in-between.
How can I specify the known focal length for those frames in PFTrack?
