Connected Compositions

connected-compositions.mdMarkdown3 KBView on GitHub

Using the connected compositions pattern, a group of layers can get their own Studio timeline, like a precomposition in After Effects.

Use connected composition when a section has its own layers or timing, will be reused, or would be easier to edit and preview on its own.

Put the scene’s markup in a named React component. Multiple internal layers and sequences can live inside it.
Render exactly one direct instance of that component inside a <Sequence>, <Series.Sequence>, or <TransitionSeries.Sequence> in the parent.
Register the same component reference with <Composition component={...}> in the root. Give it a unique id and the dimensions, fps, and natural duration needed to preview the scene on its own. A <Folder> can keep scene compositions together.
