Hi! I tracked some footage in PF Track, and everything seemed good. My test geo didn't slip or slide around. I exported it as Houdini Script. Brought it into Houdini, trackers all showed up along with the camera. But when I put the image sequence into the Camera background everything is sliding. The trackers don't match up with the background. I don't think my track was as way off as it seems with the background plate. Is there another reason why background sequence and trackers wouldn't be matching up? Any information is great! Thanks!

Are you matching your filmback / all other cam settings? I've had issues before with syntheyes not bringing in proper settings esp the focal length.


Try messing with the focal length to see if you can get your trackers to stay lined up.

I can't recall which flavour in particular, but one of the pftrack export options didn't set the correct camera resolution.

Worth checking.
