Hi James,
No luck with Small Motion. The spline doesn’t move at all.
Here’s a screenshot 11 frames in to a track using small motion.

I’ve tried clearing all keyframes, all tracks, starting from scratch with new projects and new clips. No luck.
Is there some means to return Mocha to a factory default in case it is some screwy setting somewhere? I can’t find a preference file to trash.
I’m running Mocha Pro 5 (Not sure what point release beyond that. I can’t find that info), Avid 7.0.6.2, and Mac OS 10.9.5.
thanks!
