If you want to move After Effects layers with a mocha track, it is a VERY bad idea to apply the tracking data to a null object or directly to the position, scale and rotation of your layers: The result is very inaccurate, because the skew and perspective deformation of the track is ignored if you are doing that. A much more accurate way to move layers is using a corner pin effect, but with a normal corner pin, your layers are stretched into the corner pin surface which is often not what you want. The “keep current frame” option of MochaImport+ offers an 100% accurate solution that is as easy to use as a null layer. Learn how to do “keep current frame” corner pins in less than 4 minutes!
