sequencing	Sequencing patterns for Remotion - delay, trim, limit duration of items	tags sequence, series, timing, delay, trim

Use <Sequence> to delay when an element appears in the timeline.

import { Sequence } from "remotion";

const {fps} = useVideoConfig();

<Sequence from={1 * fps} durationInFrames={2 * fps} premountFor={1 * fps}>
  <Title />
</Sequence>
<Sequence from={2 * fps} durationInFrames={2 * fps} premountFor={1 * fps}>
  <Subtitle />
</Sequence>

This will by default wrap the component in an absolute fill element.
If the items should not be wrapped, use the layout prop:

<Sequence layout="none">
  <Title />
</Sequence>

Premounting

This loads the component in the timeline before it is actually played.
Always premount any <Sequence>!

<Sequence premountFor={1 * fps}>
  <Title />
</Sequence>

Series

Use <Series> when elements should play one after another without overlap.

import {Series} from 'remotion';

<Series>
  <Series.Sequence durationInFrames={45}>
    <Intro />
  </Series.Sequence>
  <Series.Sequence durationInFrames={60}>
    <MainContent />
  </Series.Sequence>
  <Series.Sequence durationInFrames={30}>
    <Outro />
  </Series.Sequence>
</Series>;

Same as with <Sequence>, the items will be wrapped in an absolute fill element by default when using <Series.Sequence>, unless the layout prop is set to none.

Series with overlaps

Use negative offset for overlapping sequences:

<Series>
  <Series.Sequence durationInFrames={60}>
    <SceneA />
  </Series.Sequence>
  <Series.Sequence offset={-15} durationInFrames={60}>
    {/* Starts 15 frames before SceneA ends */}
    <SceneB />
  </Series.Sequence>
</Series>

Frame References Inside Sequences

Inside a Sequence, useCurrentFrame() returns the local frame (starting from 0):

<Sequence from={60} durationInFrames={30}>
  <MyComponent />
  {/* Inside MyComponent, useCurrentFrame() returns 0-29, not 60-89 */}
</Sequence>

Nested Sequences

Sequences can be nested for complex timing:

<Sequence from={0} durationInFrames={120}>
  <Background />
  <Sequence from={15} durationInFrames={90} layout="none">
    <Title />
  </Sequence>
  <Sequence from={45} durationInFrames={60} layout="none">
    <Subtitle />
  </Sequence>
</Sequence>
