I'm running PD 14.0.2820.0 on Windows 10 and I've run into a weird problem when trying to use the Motion Tracker feature for the first time: clicking the Track button simply does nothing.
I have tested this issue with a dozen of various video clips, all in 1080p resolution, with clearly visible objects. I've also tried toggling show/hide tracker box button. No success.
Symptoms: when I go to Tools > Motion Tracker, the selection box is there. I move it and resize it as desired, then hit Track button and... nothing. The yellow tracker box that's supposed to show up doesn't appear, the video clip doesn't play. If I click the Track button again, it starts playing the clip at accelerated speed, but still, no yellow box, no tracking, and after hitting Stop the selection box is right where I first put it.
Restarting the program, adding another tracker or removing the first one and replacing it with a new one don't help. It's simply as if the tracking process can't start for some reason. And I have a pretty powerful PC, it handles full HD preview without a problem.
Help please?
