Covering the process of how to create a sign replacement in After Effects using the Foundry’s Camera Tracker plugin in, Laurie Knapp stresses the importance of workflow to ease the process of trying to get an object to “stick” to a surface within your footage.

This is tutorial I created to show a good workflow I’ve worked out in AfterEffects (CS5.5) using The Foundry’s 3D Camera Tracker to match-move any 2D object (like a sign) that needs to stick to a surface within footage that was filmed with camera perspective changes (i.e. non-nodal). Because of the perspective, trying to ‘stick’ items onto surfaces can be a pain depending on the order you do things. If you find yourself constantly re-orienting and re-positioning, DON’T. Just watch and learn!
