Mocha Product Manager Martin Brennand takes alook at how to use the new mocha pro camera solver when there are moving objects in the scene. He also shows 3D export to After Effects where he attaches a 3D particle system using Trapcode Particular.

from the tutorial description: Product Manager Martin Brennand takes you through how to use the camera solver to get the 3D data of a moving planar object. Also covers unlink tracking, 3D export to After Effects and attaching 3D particles from Trapcode Particular.
With a camera solve you are normally solving from static areas in the scene (Walls, floors, rocks, etc), but when you want to capture anything moving, a little extra work is needed.
