Jorrit Schulte demonstrates how to get the Warp Stabilizer data out into After Effects keyframes with a clever technique that will work for generating position, rotation and scale and perspective keyframes for corner pin data.
In today’s tutorial you’ll learn how to convert stabilization from the Warp Stabilizer to regular After Effects keyframes
By replacing the footage that the After Effects Warp Stabilizer has processed with a new clip that has a black background with two white dots, you are then free to use the After Effects tracker to track the result.
By having keyframes you have some more control over the stabilization process by manipulating keyframes, or even key the stabilization effect on or off easily.
Without sounding to “ranty” this bring up and interesting matter with After Effects, where the JDI (just do it features) are a fantastic addition, however they stop short of giving the user back control after they have processed.
This can be seen in Rotobrush, Warp Stabilizer, and the 3D Camera tracker, as they are almost complete islands in the After Effects workflow. In fact we can probably extend that last statement to any component in After Effects where there are no logical stream connections from one building block to the next.
As an example, gravity is a feature of Particular, and the Newton Physics engine, etc. meaning that you cannot set a global gravity for all plugins and effects to respect, they have no logical idea about each other.
Expanding that premise to what the Rotobrush tool in After Effects could be, by allowing you some degree of control over the segmentation boundary, allowing you to manually move it for problematic frames, or even translate the boundary to bezier splines to integrate better with traditional rotoscoping or other workflows.
This tutorial by Jorrit is typical in After Effects workflow, finding super clever solutions to get around the fact that everything in After Effects is a lone island. So if you ever wanted to gain more control over the Warp Stabilizer Effect in After EFfects, check the tutorial here.
