Basically I’m trying to track points on a face and at points it becomes obscured by shadows. So there’s parts of the video I can track but need to create another layer for another point in the clip to track to. So I want my final output to be the combined data from both tracks, but only PART of each track.
Honestly, the best thing to do is use manual track to get past the shadow occlusion: Boris FX | Quick Tip: Manual Track
That will work best for you. But I am happy to answer any other questions you might have. You can also use adjust track as well.
