}Authorizations
API key obtained from your Tella account settings
Path Parameters
Video identifier
"vid_abc123def456"
Clip identifier
"cl_xyz789ghi012"
Body
Add a sound effect to a clip, from Tella's curated catalog (presetId) or from your own audio (sourceId).
0 < x <= 90071992547409913000
Start time. Milliseconds on the clip playback timeline (with cuts applied) — the same timeline as the cut transcript.
0 <= x <= 90071992547409911000
"Whoosh"
Preset ID of a curated Tella sound effect, from a default item in GET /v1/library?scope=default. Placing one copies the effect into a source owned by your workspace, so nothing needs uploading. Mutually exclusive with sourceId; exactly one is required.
"cha-ching"
Source ID for the audio, from POST /v1/sources (kind: audio with the audio's duration) or from a private/workspace item in GET /v1/library?type=sound-effect. When uploading, send the audio file as-is — MP3, WAV, M4A, … — no need to wrap it in an MP4. Mutually exclusive with presetId; exactly one is required.
"su_abc123"
Playback volume (0 = muted, 1 = original). Defaults to 1.
x >= 01
Response
OK
A sound effect on a clip
A sound effect on a clip.
