Adjusting a tracked mask?
on Aug 24, 2019 at 9:57:47 pm

I tracked a mask that was wonking out at a certain part of the track. I thought it would be easy to adjust by selecting the multiple offending points and then selecting ALL the keyframes in the track and nudging the bogus points into position but it would deselect every keyframe except the one I was sitting on making it look worse.

What is the workflow here? Is it not possible to do this in AE? If I need to do stuff like this in Mocha that is fine but I am pretty sure I must be missing something.

Thanks in advance!

Hi Dave,

As far as I know, there's no way to directly manipulate multiple mask keyframes. But, of the mask isn't changing, then the easiest approach would be to create a Null Object and parent your mask layer to it, then you can adjust the null's position and the Mask layer will follow it.

You might also want to try the Track Mask option in the Tracker controls. That might take care of a lot of the work for you.

It's much easier to do in Mocha, as the mask keyframes are kept separate from the tracked keyframes.
