Motion films that never cut to the next slide. A Claude Agent Skill that makes product launch films, teasers and feature demos where every beat grows out of the one before — one continuous take, not a stack of scenes. 一镜到底的连贯动效。 做产品发布片、预告片、功能演示：每一个画面都从上一个画面里长出来，是一整条连续的镜头，而不是一张张轮流出场的"PPT"。

_{From onetake's own launch film. A prompt bar opens into the ad it asked for; the next prompt collapses into a line that shoots across the desk and opens into a festival screen. No cut. Full film with sound →}

Most motion videos an AI makes today — and most template tools — come out loose. Title card, fade, UI shot, fade, feature card, fade, logo. Each shot can look fine and the whole still reads like a slideshow, because nothing connects one beat to the next: scenes replace each other.

onetake treats the boundary between two beats as the thing to design. At every boundary, something on screen survives and visibly becomes the next beat:

• the prompt bar opens into the app window; the window reflows into the phone;
• a bar collapses into a line, the line shoots across the desk and becomes the first grid line of the next film;
• a card grows into the page; a stage opens from the character; the camera pushes through a card until it is the next scene;
• at the end, the cast folds into the lockup — in the launch film, the block cursor writes the name in one stroke.

And one camera holds it all together. It never cuts: it follows the subject a beat ahead, whips to where the next thing will land, floats like a hand-held operator and shakes when something hits — then holds dead still, because rests are what make the moves land.

Every film is checked by an oracle before a human watches it. probe.py records what is on screen in every frame, finds each boundary, and asks what carried across it. A film whose beats replace each other fails.
