warning

Draft API: This API is experimental and may change.

duplicate-composition.ts
import {duplicateComposition, type CodemodProject} from '@remotion/codemods';

declare const project: CodemodProject;

const result = duplicateComposition({
  project,
  compositionFile: 'src/Root.tsx',
  compositionId: 'MyComposition',
  newId: 'Portrait',
  metadata: {width: 1080, height: 1920},
});

console.log(result);

Both registrations reference the same component implementation. Default props and other registration props are copied. The original registration kind is preserved: a <Still> remains a <Still>.

<Still> registrations only support width and height overrides; supplying FPS or duration throws an error.

The project file containing the composition registrations. Registration edits support <Composition>, <Still>, and <Folder> with their original import names and static IDs or folder names.

Returns an object with the following properties.

The updated project. Unchanged files and extra project fields are preserved.

An array of {filePath, previousContents, nextContents} file changes. A null content value indicates a created or deleted file.
