}Duplicate a Tella Motion document
Copies a document under the same owner and optionally edits the copy in the same request with commands. Use it to reuse a design with other content, such as the same title card with another heading. The copy is independent of the original.

Path Parameters
Tella Motion document ID (ffd_…), from GET /v1/motion/documents.
Body
Copy a document under the same owner. The copy is independent: later edits to either do not reach the other.
The copy's name.
1"Topic title: Pricing"
Edits to run on the copy, as POST /v1/motion/documents/{id}/commands takes them, e.g. setTitle to give the same title card another heading.
1 - 256 elementsOne edit in a batch: an editor command (camelCase type, times in seconds) or an op (dotted type, raw render timeline values). See https://docs.tella.com/mcp-tools/motion-commands for every command and op with an example.

The curve's name.
^[A-Za-z0-9][A-Za-z0-9._-]{0,127}$setCurve A number, keys, or an expression over other curves; null removes it. Every reader (bindProperty, a shader uniform) sees the same value at the same canvas time.
Response
Created
The copy and, with commands, the batch's result
A Tella Motion document: a render timeline (a tree of media, sound, text, shape, sequence and composition nodes) that a Tella Motion clip, overlay or b-roll plays live, so edits show in the video at once.

"2026-10-22T10:00:00.000Z"
Document ID
"ffd_abc123"
"Lower third"
The owner's ID: the video's, for story documents; yours, for user documents.
"vid_abc123"
Who owns the document: story for a video's own documents (its Tella Motion clips, overlays and b-roll), user for one of yours that no video plays yet.
"story"
The clip that plays this document, when it is a Tella Motion clip's. Absent for overlays and b-roll.
