I’m working on tracking the torso of a man driving. The first time I tracked the shape, it was a pretty solid track. Then, thinking I could get it to be better, I added perspective to the default parameters and the track was terrible. I wanted to return to the original track but all the command+Z pushes in the world doesn’t seem to undo the track and get me back to the original good track. Any way to erase the tracking data and start over?
