I was ┬áhired to track and composite a logo patch onto the lab coats of doctors in various shot of a promo video. I initially tried variations of the built-in tracker in After Effects but wasn’t getting the quality that I wanted. So I upped my tracking game to Mocha. That worked like a charm. It maintained the perspective of the patches and also allowed me to modify the shape of the patch in Photoshop to match the shape and distortion on any jacket folds.
It was great to actually have a green patch to track because I could also use that as a key to composite the patch behind the video layer and not have to worry about masking out the overlap from the collars and stethoscopes.
