Rotoscoping - the art of isolating objects in a video with animated masks - becomes very tricky if the object you want to isolate has a lot of motion blur. In the heavily blurred edges of the object parts of the background will be visible that are a bit tricky to eliminate. In this tutorial you learn how to rotoscope such blurry objects in Adobe After Effects. We will first do a normal rotoscoping with a hard edge and then recreate the blurry edges such that no background will be visible anymore.
