A composition is what you'll eventually publish or export from Descript. Every project has at least one composition, but you can create more for special purposes like rough drafts, social clips, or alternate cuts.
Editing in a composition is non-destructive, meaning you can make changes to your media without permanently changing the source media.
Enable multiple compositions
To enable multiple compositions, click your project's name at the top of the editor and click Enable multiple compositions. This opens the compositions panel, where you can create, view, and access compositions in your project. To access the composition panel later, simply click on the composition's name located next to your project's name in the editor's header.
