Beginner question: Content-Aware fill with Rotobrush

[Shmoons]

Hi

I'm new to AE and i wondered how to content-aware fill a roto-brush selection, if even possible.

I've selected my pupils in a video with the rotobrush and want to fill them so they become completely white. Does someone know how to do this?

Any tips are much appreciated.

If you are new to AE, please spend at least a couple of hours with the User Guide. You'll find links on this forum, the AE product page, and AE's Home Screen.

If you have successfully used rotobrush to create a matte for the pupils in your eyes then you have already poked a hole in the layer. You just have to invert the matte and then drop a white solid below the rotoscoped layer. Content-Aware Fill is the wrong tool for something like this. Depending on the shot Rotobrush may have been a very inefficient way to create the matte. I would have to see the shot and your timeline to be sure and to make any meaningful suggestions.

BTW, make sure you freeze Rotobrush when it is complete or it will start analyzing all over again and it may come up with a matte that has problems. It's a common newbie mistake.

Well, frankly this sounds like an utterly rubbish workflow to begin with. Rotobrush being based on actual pixel information and thus sensitive to compression artifacts or even the regular stairstepping patterns this is likely not going to look great. That and it sounds like calling in the Army to change a light bulb. What's wrong with a good old circular mask and mask tracking?
