- [Add a clip from an uploaded source](https://www.tella.com/docs/api-reference/clips/add-a-clip-from-an-uploaded-source.md): Add a new clip to a video. Create a source via `POST /v1/sources`, PUT the bytes, then pass the returned `sourceId` here.

- [Add a layout to a clip](https://www.tella.com/docs/api-reference/clips/add-a-layout-to-a-clip.md): Adds a layout to a clip. Provide both startTimeMs and durationMs for a time-ranged layout, or omit both for a clip-spanning layout.
- [Add a sound effect to a clip](https://www.tella.com/docs/api-reference/clips/add-a-sound-effect-to-a-clip.md): Adds a sound effect to a clip from an uploaded audio source. Call `create_source` first.

The clip's existing layouts are replaced: the AI picks an editing style (or follows `style`), sets the clip's base layout, and adds time-ranged layout changes.

- [Auto-generate zooms from mouse activity](https://www.tella.com/docs/api-reference/clips/auto-generate-zooms-from-mouse-activity.md): Generates tracking zooms from the mouse clicks in the clip's screen recording — the API twin of the editor's "Generate zooms".

- [Cut clip ranges by transcript word indices](https://www.tella.com/docs/api-reference/clips/cut-clip-ranges-by-transcript-word-indices.md): Cut one or more ranges from a clip by referencing word indices in the transcript.

- [Get a source thumbnail or animated preview](https://www.tella.com/docs/api-reference/clips/get-a-source-thumbnail-or-animated-preview.md): Get a thumbnail of a source.

- [Get clip transcript](https://www.tella.com/docs/api-reference/clips/get-clip-transcript.md): Returns the words spoken in a clip with cuts applied — what viewers actually hear. Times are in ms relative to the clip's playback start. Word indices are stable identifiers for cut-by-transcript; they don't shift when cuts change.
- [Get silent ranges in a clip](https://www.tella.com/docs/api-reference/clips/get-silent-ranges-in-a-clip.md): Returns silent ranges in a clip's audio, in ms on the clip's playback timeline (cuts applied) — pass ranges directly to the cut endpoint.
