I want to do some retouching an a video shot and it would help to be able to use a marker to "paint" a mask.
By paint I mean how you paint with the grease pencil. But instead of your mouse cursor you use a tracking marker to paint.
Is there any way to do something like this?
EDIT: In my shot the actor pretends to spray paint a wall that is already finished (We forgot to shoot an important shot at the beginning). Now I tracked the sprayer and want it to "paint" the color on the wall.
But I can imagine other use cases for a functionality like this.
