Mamoworld has a new After Effects video tutorial, Monster Face, which applies advanced tracking techniques from Mocha to modify a mouth and face in After Effects. We also add some other resources to help round off the picture.
This work was done before both the 3D tracker and Face Tracker appeared in After Effects. It also could be aided by the Stabilized Precomps feature of MochaImport+ or MaskTracker+, newer AE scripts from Mamoworld.
Ckeck out Todd Kopriva’s Face replacement with mocha from David Torno about PVC tutorials by Torno on how he did tracking, compositing, and other post-production work for a music video (on Vimeo for mobile users). The cmiVFX training Nuke Facial Replacement Techniques looks interesting too.
