1:00ish After Effects – Object Matte / RotoScoping

Rotoscoping sounds like some unfortunate experience at the dentist. I promise it is not that bad, at all. In fact, in After Effects it is now called Object Matte Tool, now doesn’t that sound better?
Rotoscoping is simply masking out something in your shot that just doesn’t belong. Simply put, rotoscoping is selecting moving footage over time and blocking it out.
direct from Adobe….
Rotoscope animation describes the process of creating animated sequences by tracing over live-action footage frame by frame. Though it can be time consuming, rotoscoping allows animators to create lifelike characters who move just like people in the real world.
The technique of rotoscoping also made the lightsaber possible.
To create these visual effects in the original Star Wars films, animators drew the color and glow of each lightsaber over the sticks the actors held on every frame in which they appeared.
In After Effects, there is a very powerful tool – the RotoBrush – now called Object Matte Brush

We can use AE with Premiere in very easy ways. Let’s adjust our workflow slightly for this. We’ll start in Premiere and dynamically link to After Effects. If you see the workflow, After Effects usage in your production work is less intimidating.
