Depends on the tool and what you are masking.
Some tools allow you to identify an edge of a region in a scene (like a tv screen, car window, or whatever), then apply a mask to that region. As the region moves (as identified by the edge detection), so will the mask.
Doesn't always work (it needs nicely defined edges that don't deform too much), but it's not bad.
