I need to "censor" some parts of a clip to cover up those private parts exposed in some family videos of my young kids. I tried using a graphic, but every few frames, I had to put another one and this took over an hour, and I got maybe 5 minutes of footage actually "covered", though it looked hideous. I am surprised that nothing I have found seems to even address anything remotely similar that I can follow for instruction.
Unfortunately, you have posted to the Tips & Tricks sub-forum, which is a repository for articles on how to do things in Premiere.
I will Move your post to the main PrE Forum.
As for your question, I would create a Filled Rectangle in the Titler, sized as necessary, then Keyframe the Fixed Effect>Motion>Position, to follow over the subject's eyes.
