Those edges don’t look like they need sharpening. They’re probably jagged because of a mistake with premultiplication, which tells the computer whether or not semi-transparent pixels include information from the background upon which they were originally shot, in a nutshell.

You are quite right, sharpening is not the best word. I'm going to change the title of the question.

I'm working on an experimental video that uses a mask of a person. Some of the masks were made in After Effects using the roto brush tool at full resolution, as is recommended.

Some however were not and done at a much lower res. The result is naturally masks with visible pixel notches in them as you can see below.

Ideally within Premiere Pro where I'm editing the video, are there any reliable ways to simplify the mask edge ?
