I work as a motion designer, and one day I was approached by a client who needed to “cut” an old logo from dozens of videos and replace it with a new one. The manual work would have taken weeks!
Fortunately, I had Mocha Pro. Its tracking and Planar Tracking got the job done in a couple hours. The client was thrilled, and I've been using Mocha ever since for all projects that need accurate motion tracking.
