Quick Examples

Create an animated intro

Create a 1920x1080 composition called "Intro" at 30fps, 5 seconds.
Add a text layer saying "Welcome" centered on screen.
Apply a slideInUp animation with easy ease.
Add a subtle glow effect.

Build a lower third

Create a modern lower third:
- Name: "Sarah Chen"
- Title: "Lead Designer"
- Blue primary color
- Animate in and out
- 5 second duration

Add physics-based motion

Add a bounce expression to the position of "Logo" layer.
Set amplitude to 0.15, frequency to 4, decay to 6.
