Details of a video shared with a CutLuma link (cutluma.com/watch?v=…): title, kind, size, length, direct file, embed and thumbnail URLs.

The signed-in user's CutLuma projects, newest first, with ids, sizes and durations. Needs the user's sign-in or an agent key.

Start an empty project. format: 16:9 (YouTube), 9:16 (TikTok, Reels, Shorts), 1:1, 4:5 or 21:9; or give width and height. Returns the id and the link the user opens so you can edit it.

Tracks (top to bottom) and every clip with id, kind, start and duration in seconds, as last saved. Use before editing. full=true also lists caption clips.

Videos, images and sounds the user has uploaded or recorded: id, name, kind, duration. Put one on the timeline with the addMedia op.

The spoken words of the project’s clips placed on the timeline (start/end in seconds), when the clips have been transcribed. If this is empty, get_media_transcript transcribes a file (also one that is not on the timeline yet), or run the addCaptions op.

Whether an editor tab is listening for this project. If not, returns the link the user must open. Editing, frames and export need it.

The full catalogue of ops the open editor can run (name, arguments, meaning): text, captions, trims, colour grading, sound, effects, AI tools… Call once per session before edit_project.

Run one or more ops from list_edit_ops in order, as one undo step. Returns what changed (or why an op failed) and the new timeline. Times are seconds; clip ids come from get_project. Ops that only measure (loudness, scopes) return their data here too.

The composited picture at a time, as a JPEG, so you can check framing, text, colour and layout. Moves the playhead there. With clip, that one clip alone (its crop, grade and effects, nothing in front of it or behind it) — also the way to see a multicam angle that is not on air.

A grid of frames across the project (or between from and to), each stamped with its time. The quickest way to review an edit. Give times to see exact moments instead (both sides of every cut, say); give clip to see one clip alone across its length.

A contact sheet of a video in the media library (or the picture itself, for an image): frames across the file, each stamped with its time in the file, without putting it on the timeline. Use it to find the part worth using in a long recording: look at the whole file, then closer with from / to, then view_media_frame for one moment. Runs in the open editor.

One frame of a library video at a time in the file (or a library image), as a JPEG: the file itself, with no crop, grade or titles.

The words said in a library video or sound file, in lines with their times in the file (seconds), whether or not it is on the timeline. COST: a stretch that was not heard before is transcribed now with the user’s AI time (paid plans): one AI minute per minute of sound, silence is free. What was heard is kept, so asking again, or captioning the file once it is on the timeline, costs nothing more —

Loudness over time of a library video or sound file: RMS in dBFS per step (−100 = silence), the quiet stretches (pauses, dead air) and the loudest moments (a clap, laughter, applause), all in seconds of the file. Finds where the talking is without transcribing. Free. A long file takes a while the first time: it may answer with a job id (poll get_job).

Render the project to MP4 in the user’s editor, save it to their library and return a share link. Takes about as long as the video, so this returns a job id at once: poll get_job. The plan’s limits apply (Free: 1080p with a watermark).

Status (queued, running, done, failed) and result of an export or any call that answered "running".
