Question 1

What is the Roto Brush tool used for in After Effects?

Accepted Answer

The Roto Brush tool is used to isolate a subject from its background without using a green screen. It allows for quick and semi-automated rotoscoping, helping users create clean cutouts and professional composites.

Question 2

What’s the difference between Roto Brush 1 and Roto Brush 2?

Accepted Answer

Roto Brush 2 uses Adobe Sensei AI to provide better edge detection and faster frame propagation compared to the original Roto Brush. It’s ideal for complex footage like hair, fast motion, or soft edges.

Question 3

How do I make my Roto Brush selection more accurate?

Accepted Answer

Use the Refine Edge tool to handle tricky areas and adjust settings like feather, contrast, and shift edge. Always freeze your propagation when you're done refining to lock in your changes.

Question 4

Can I use Roto Brush directly in Premiere Pro?

Accepted Answer

Not directly. Roto Brush is an After Effects feature. However, you can use Dynamic Link to bring After Effects compositions into Premiere Pro, making integration seamless for editing workflows.

Question 5

Why is my Roto Brush not working properly?

Accepted Answer

Common issues include not working in the Layer panel, having a low-resolution base frame, or needing more manual refinement. Always double-check you’ve selected the correct panel and frame to start.
