you can teach an old Door New Tricks
one of the biggest worries for me for this project was the doorway effect. in which a door shape beam of light appears and gilly is thown into it. The Big issue with this effect was the act of rotoscoping around the actor, which is keyframing a mask over and over until the actor is cut out the shot. This would be a time consuming effort and would be practically on par with animation.
Luckily i came across a time saving method that works effectivly. This tool helped me draw around my target and it would track automatically for me
