Understanding IN/OUT animations

How entrance and exit animations work, how to set presets, duration and delay on a subcomposition.

ConceptIntermediateUpdated

IN/OUT animations define how your overlays enter and exit the screen.

How it works

Each subcomposition has two animation slots:

  • IN animation: plays when the overlay appears
  • OUT animation: plays when the overlay disappears

You set these in the Inspector when you select a subcomposition. Individual elements also have their own IN / OUT (and UPDATE) animations.

Setting an animation

  1. Select a subcomposition in the Composition Tree.
  2. In the Inspector, find the Animation section.
  3. Choose an IN preset from the dropdown.
  4. Choose an OUT preset from the dropdown.
  5. Set the duration (default: 500ms).

Available presets (52 total)

Some popular presets:

  • fadeIn / fadeOut: simple opacity fade
  • slideInLeft / slideOutLeft: slide from/to the left
  • slideInRight / slideOutRight: slide from/to the right
  • slideInUp / slideOutDown: slide from bottom / to bottom
  • popIn / popOut: scale bounce effect
  • news-slideIn: classic news lower third animation
  • sports-wipeIn: sports-style wipe effect

Duration

Set in milliseconds. Common values:

  • 300ms: quick, punchy
  • 500ms: standard broadcast feel
  • 800ms: smooth, cinematic
  • 1000ms+: dramatic, slow reveal

Delay

You can add a delay before the animation starts. Useful when multiple subcompositions need to animate in sequence.

Tips

  • Match IN and OUT directions (slideInLeft + slideOutLeft looks natural).
  • Use the same animation style across all overlays in a graphic for consistency.
