CutLuma video editor

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

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.

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.

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: 720p with a watermark, videos up to 10 minutes, 10 exports a month; Starter 1080p; Pro and Business 4K).

Find animated video templates by keyword, format (9:16 for TikTok/Reels/Shorts, 1:1, 4:5, 16:9 for YouTube), category (Trending formats, Social posts, Hooks & intros, Lists & tips, Tutorials & courses, Stats & data, Quotes & stories, Sales & business, Real estate, Construction, Medical & health, Product & launch, Creators, Food & drink, Fitness & wellness, Fashion & beauty, Travel, Music & nightlife, Events, Holidays, Education & school, Kids & family, Gaming & esports, Tech & SaaS, Finance & money, Cars & automotive, Sports, Pets & animals, Home & interior, Hotels & hospitality, Nonprofit & causes, Local services, News & media, Weddings & love, Corporate & HR, Memes & humor, Faith & spirituality, Science & nature, Art & photography, Books & writing, Film & entertainment, Government & public info, 中文 · Chinese, हिन्दी · Hindi, Español · Spanish, عربي · Arabic, Français · French, বাংলা · Bengali, Português · Portuguese, Русский · Russian, Bahasa Indonesia · Indonesian, اردو · Urdu, Deutsch · German, 日本語 · Japanese, Türkçe · Turkish, 한국어 · Korean) or language (en, zh, hi, es, ar, fr, bn, pt, ru, id, ur, de, ja, tr, ko). Each result has an "open" link that loads it in the editor.

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

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).

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 (Business plan): 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 — the result says how many AI seconds this call used and which stretches are known. Give from / to to listen to part of a long file (get_media_levels shows where there is sound, for free). A long stretch answers with a job id: poll get_job.

Read any CutLuma content page as Markdown: "/" (overview, plans, features), "/tools", "/tools/<slug>", "/video-editor", "/video-editor/<slug>", "/guides", "/guides/<slug>", "/templates", "/templates/<id>".

Current CutLuma plans with price, billing interval, limits and what each includes. The editor is free to start; every AI feature is part of the Business plan.

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.

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

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.

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.

All 71 single-purpose tools (captions, screen recorder, resize, trim, remove silence, add music, green screen, GIF maker…) with what each does, whether it is free or which plan it needs (every AI tool is on Business), and the link that opens it.

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

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

A link the user can open to start right away in the CutLuma editor with a tool or template ready. tool is one of: captions, record, resize, silence, shorts, product, testimonials, trim, text, music, montage, camera, voice, speed, tts, translate, greenscreen, cutout, prompter, stock, textvideo, magicdesign, aiimage, bgremove, magicedit, visualizer, charts, industry, effects, translatedesign, localize, transcript, dub, publish, present, open, subtitles, textbehind, tracking, subjectfx, colorchange, freezeintro, guide, hub, narration, agent, grade, styles, mixer, multicam. language is a two-letter code for captions (e.g. "ar", "es"). With neither, a blank project opens.

Returns matching pages with links, a Markdown URL for the full text and, where it applies, a link that opens the editor with that tool or template ready.

CutLuma's series of researched guides on earning money with video (start here, service business, channel business, platform income, platform payouts, retainer service, local service, digital product, commission income, audience business, localization service, ad creative, operating system, lead generation). Without arguments: every part with its business model, key facts and takeaways. With "topic": the parts that match (e.g. "clipping", "YouTube pay", "UGC", "real estate", "course", "affiliate", "podcast", "translate"). Each part cites its sources; read the full text with get_page. Figures are published ranges and worked examples, not promises of income.

Recommended aspect ratio and pixel size for YouTube, Shorts, TikTok, Instagram Reels/Stories/feed, Facebook, LinkedIn and X, with safe-zone advice for vertical video.

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.

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 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.
