Hasta La Motion!

I’ve a little problem with some PFTrack projects. We are doing a puppet short in which we are replacing the puppet heads with CG ones. And with the Geometry Tracking possibility the whole process works quite well. Most of our shots are already tracked. Some have free cameras, but the most shots have stationary cameras. So the basic structure of our projects is: one tracking group for the camera (free/stationary) and one or more groups for the moving geometry.

Now the problem. The director decided to enlarge some of the shots. More than we have handles. Meaning that we had to extend the PFTrack projects. When the camera is a free one, the extending works very well. We camera track the new frames of the shot and then the geometry.

But, if we have stationary camera, there isn’t the possibility to extend the solved motion. Therefore the stationary camera only has keys for the "old" frame range. Unfortunately the geometry track doesn’t work if the is no full solved camera. If I reset the camera the geometry motion will be dropped as well. I also tried to copy the camera keys but it didn’t work.

Does anybody know a solution or a work around for this issue. It would be too bad if we have to track every shot once again.

Thanks in advance.
