onetake is a Claude Agent Skill that makes product launch films as one continuous take, with a script that scores how much of each shot carries into the next

onetake is a two-day-old Claude Agent Skill that produces a 15-to-30-second product launch film as a single continuous camera move, where each beat visibly turns into the next, and every version is checked against a Python script that measures how much of one shot carries into the next before a person sees it. It has 585 stars.

Why it mattersMost AI-made launch films look like a slideshow of unrelated cards. This skill treats each cut as a design problem and rejects the film if a Python script cannot see one element survive it, which is the first automated check we have seen for that specific quality.

Most AI-made motion videos come out looking like a slideshow of unrelated cards fading into each other, and onetake is a Claude Agent Skill that treats the space between two shots as the thing to design. The skill was published to GitHub on 26 September 2026 by feitangyuan and has picked up 585 stars in the two days since, with 41 forks and ten worked-through example films in the repository.

What it makes

The skill produces a 15 to 30 second product launch film, teaser or feature demo where the camera never cuts. Every boundary between two beats has something on screen that survives it and becomes the next beat. The launch film for onetake itself opens with a prompt bar that unfolds into a running app window, then collapses the app back into a single line that shoots across a desk and becomes the first grid line of the next scene. There are ten example films shipped in the cases/ folder, each with the finished video and a written breakdown of the concept, the beat sheet and the versions that were rejected on the way to the final.

The automated check

Every film is scored against a Python script called probe.py before a person sees it. The script records what is on screen in each frame, finds each boundary between shots, and reports what visibly carried from one to the next as a single number called the carry score. An earlier launch film was rejected twice, at 0.00 and then 0.40, before its third version scored 0.75 and was accepted. The onetake launch film scores 0.83. The same script also fails films that hold every shot for the same length, that never sit still, that clip their audio, that move fast without motion blur, or that let the subject leave the frame.

How the render works

The product's interface is rebuilt in HTML from screenshots rather than screen recorded, so the camera can push into any zoom without pixelation. Roughly 38 measured moves make up the animation library: springs, entrances, collisions, camera moves and fluid grounds, each written as a pure function of time with a speed curve fit to reference footage. Motion blur is real: every moving frame is four samples averaged in linear light across an open 180 degree shutter. Drafts render at 1080p30, finals at 4K60. The whole pipeline is deterministic, so seeking to any time returns the same frame.

The licence to watch

onetake is under the PolyForm Noncommercial 1.0.0 licence, which is free for personal, educational and research use but does not permit commercial use. A studio that wants to use the skill on client work will need permission or a different licence from the author. That constraint matters here because the whole point of the skill is finished launch films for products.

The oracle script is the part worth copying even if the skill is not adopted whole: an automated test that fails a video when nothing visibly carries between two shots is a specific check that we have not seen elsewhere.
