Freeze frame
For agents: this is one tool of an MCP server, as the server described it to aiagentboard.org's probe.

Freeze the picture at a frame: the clip is CUT there and a still of that frame is inserted between the halves, pushing everything after it later (the NLE 'frame hold'). This is how you hold a moment — play, freeze, continue. The still is an ordinary IMAGE layer showing that frame for holdFrames (default 150 = 5s at 30fps), so you resize, split, move or delete it like any other layer. image is the filename of a PNG of that frame, already uploaded to the project's assets — rendering one needs a browser, so capture and upload it first. The reply's frozenSourceFrame is the SOURCE frame that was frozen, which differs from frame on a retimed clip. frame must be strictly inside the clip.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| elementId | string | yes | video.<id> to freeze. |
| frame | number | yes | Project-timeline frame to freeze at — must be strictly inside the clip. |
| image | string | yes | Filename of an already-uploaded PNG of the frozen frame, in the project's assets. |
| holdFrames | number | no | How long the still holds, in frames. Defaults to 150 (5s at 30fps), the same default every added clip gets. |
| projectId | string | yes | Opaque project id (a v4 UUID, from list_projects/create_project). Selects which existing project this call mutates. |
| anonymousToken | string | yes | The token create_anonymous_account returned. This connection has no Morpha key, so every call carries it. |
