Roto Edge Extension in Fusion

Sometime when rotoscoping, you’ll want to extend the edge of your shape to avoid the background colors bleeding onto your subject.

For example, if you’re cutting out a person from a greenscreen backdrop, and blur pixels around the edge, you may get some green pixels that make it in there.

By extending your edge, you can avoid that.

There are a few ways to accomplish that in Fusion, and Chadwick walks us through a couple in this video.

In this video from Editing Playbook, you’ll learn about:

  • Multiply by mask
  • Using a Clean Plate
  • Alpha Divide & Blur
