Motion tracking is simply your ability to track the motion of a particular shot, and then apply the same motion to added elements in your footage. What is Motion Tracking in After Effects? So, what is motion tracking and how can you use it in your next project? Check out our guide to the 6 main types of motion tracking in After Effects and how you can use them in your next creative journey. It is the key feature that allows us to blend fantasy with reality. This feature allows you to place new elements in a scene, and have them behave as if they were there all along and the camera simply exists around them. Next, select your preferred export, and select the target layer, and hit apply.Motion tracking is one of the most-used features in After Effects, and for good reason.
In the Mocha Pro interface, select the “create transform data” button and select your tracked layer to create the tracking data from. This is how you keep a full res image anti-aliased and prevents over-processing the image and losing image quality. Now you can select the new pre-comped composition and toggle on “collapse transformations.” What this does is this allows you to take a really large file and have it adjust the transformations of the layer so that they don’t alter when you add a new transformation over the top like a corner pin. In AE, for oversized corner pins to line up properly with your AE composition and pass the large frame without losing resolution, you need to pre-comp your insert and you MUST make sure to select “leave all attributes in composition." In Mocha, after tracking to your satisfaction, set your reference frame where your insert lines up by using the “align surface” tool on the matching frame. However, if you are trying to insert an oversized insert, larger than the comp, you may find the basic megaplate corner pin workflow useful.
While the exact workflow is different, you might find this tutorial helpful for using align surface with mismatched resolutions in AE: Boris FX | Align Surface and Mismatched Resolutions
