}Add a source to the library
Saves an uploaded source to the library so it can be listed and reused later, both here and in the editor’s media panels. Create the source via POST /v1/sources and upload the bytes first, then pass its sourceId. Without this a source is only reachable through the clips that already reference it.

Body
Save an uploaded source to the library so it can be listed and reused later. LUT sources must be valid 3D .cube files with LUT_3D_SIZE at most 65. Apply a saved LUT using its item id in PATCH /v1/videos/{id}/clips/{clipId}/filters
Source ID from POST /v1/sources, with the bytes already uploaded to its uploadUrl
"su_abc123def456"
Display name shown in the library. Defaults to the item's type.
1 - 255"Intro camera take"
Where to save the item (default: private). workspace shares it with everyone in the workspace and requires an owner or member role; viewers get a 403.
private, workspace "private"
Expected item type. Optional — the type is taken from the source's own kind; supplying a value that disagrees is an error.
image, video, sound-effect, lut Response
Created
The newly created library item
A placeable piece of media — either saved to a workspace's library, or an entry in Tella's curated catalog
Hide child attributes
Hide child attributes
Unique library item identifier
"media_abc123def456"
Display name shown in the library
"Intro camera take"
Which set of media to read: private (only visible to their creator), workspace (shared with everyone in the workspace), or default (Tella's curated sound effect and background music catalogs, which hold no other media type)
private, workspace, default "private"
The kind of media the item holds
image, video, sound-effect, music, lut, screenshot "video"
Catalog grouping, for default items only — the same grouping the editor's sound effects and background music panels show
"Everyday"
ISO-8601 creation timestamp. Absent for default catalog items, which are served from Tella's catalog rather than stored as rows.
Duration in milliseconds, for time-based media
4200
Preset ID, for default catalog items only. A preset has no source, so pass this instead of sourceId: a sound-effect preset goes to POST /v1/videos/{id}/clips/{clipId}/sound-effects (placing it copies the effect into a source owned by your workspace), a music preset to PUT /v1/videos/{id}/background-music.
"cha-ching"
Source ID. Pass it anywhere a sourceId is accepted — clips, layouts, overlays, sound effects. Present for every item added through this API, including images. Absent for items added in the editor, which have no source, for music and LUT items, and for default catalog items, which use presetId instead.
"su_abc123def456"
ISO-8601 update timestamp. Absent for default catalog items.
Hosted media URL, for image, screenshot, music and lut items, and for default catalog items, where it is a publicly fetchable preview of the audio (for music presets it is also the track the video will play). API-created images expose this alongside sourceId; use sourceId to place the image on a clip, since overlays and layout media do not accept URLs. Editor-created screenshot items have a URL but no sourceId; use POST /v1/library/screenshots to capture a new placeable image or video.
