Re: Animating Mask or better solution

I don't know nothin' about nothin' but I might try motion tracking the whole shabang in sections. I would use points on or close to the trail itself as your track points. Then you could apply that tracking data to an empty layer. THEN you could draw a mask on that empty layer onto the trail in sections. And since you've tracked it, the mask should stay on the trail as you go. I'm sure it will take a lot of tweaking, but letting the motion tracker keep the mask glued to the trail is better than animating it frame by frame (god forbid).

You might've already tried that, or maybe the footage is too shaky even if you adjusted the sensitivity of the tracker settings, but that's how I'd approach it.
