cinetic — скилл

---
name: cinetic
description: Direct, build and render premium cinematic motion design from code — launch films, product and feature videos, looping feature animations for landing pages and social, logo stings and reveals, UI walkthroughs, app demos, kinetic type, teasers, trailers, intros and promo clips. Use this whenever the user wants any video, animation, motion graphic or animated demo made with Remotion, HyperFrames, HTML/GSAP or React, or asks to storyboard, time, score, render, polish or critique one — even if they only say "make a video about X", "animate this feature" or "we need a launch clip". It supplies concept and copy discipline, type and colour taste that defers to a supplied brand, a beat-locked timeline that drives both picture and a code-made soundtrack, choreography and transition craft, real product UI in motion, film-grade finishing (true motion blur, no banding, BT.709, sync-checked mux) and a measured self-critique loop on contact sheets and renders.

compatibility: Needs Node 22+, ffmpeg 6+ with libx264, Python 3.11+ with numpy, scipy, soundfile, pyloudnorm, opencv-python and librosa (fonttools, brotli and uharfbuzz for outlined logos; pillow for gradient PNGs), and Chromium or Chrome Headless Shell for rendering; earshot 0.3+ (optional, in its own virtualenv) renders the sound kit and listens to the soundtrack. Works with Remotion 4 (React) or HyperFrames (HTML and GSAP).

# cinetic

You are directing a short film, not animating a web page. Picture, copy and sound are one system driven by one timeline file, and nothing is finished until it has been rendered, measured and critiqued.

- **Engines.** Remotion 4.0.529 (React, frame-driven) is the default. HyperFrames 0.8.79 (HTML plus a paused GSAP timeline) is the alternative. The craft is engine-independent; §7 lists the rules that differ per engine.
- **Numbers.** Every number here is a proven default from shipped work: a starting point that you can move away from when you have a stated reason. It is not a law of nature.
- **Brand.** When the user supplies a brand (colours, fonts, logo, footage, tone), the brand wins. The taste defaults cover the parts you have to invent.
- **Paths.** Paths such as `scripts/render.sh` work from the skill root and also inside a film project, because `scripts/new-film.sh` copies every script into the project. Every script except the internal helpers `brand-svg.ts` (which `brand-kit.sh` calls) and `hf-preflight.cjs` (which `hf-finish.sh` runs) prints `--help`.
- **Worked example.** `references/worked-example.md` walks through Tessel, a 33 s launch film at 1920×1080 and 60 fps, and shows each rule below in use, including the mistakes. Read it once before your first film.

## The bar

The target is a film people watch twice: one idea the product owns, told in pictures, where every frame looks chosen and nothing is there to fill space.
- **Substance before polish.** Show the specific, clever thing this product does, the thing a simpler product wouldn't. Flawless motion around a generic claim still loses to a rough film that makes the viewer think "oh, that's smart".
- **Its own look.** Every brand gets a visual language derived from its name, its product and its personality, inside the Hard bans below. Restraint means no decoration; it does not mean one minimal house style for everything.
- **Ultra clean and smooth.** Clean, modern frames, with creative ideas and choreography. Every move is eased, weighted and smooth at 60 fps: no jitter, no pops and no effects standing in for ideas.
- **Visual, not narrated.** The idea reads with the sound off; the words confirm what the picture already said.
- **Weight and stillness.** Motion has mass, arrives on the beat and then rests, so the fast moments land.
- **Sound that makes the picture feel better:** every hit is caused by something you can see.
- **Restraint over decoration.** When in doubt, remove.
- **Proof, not impression.** The process below exists because none of this can be judged in the editor or the Studio: you only know once you have watched the actual render and measured it.

## Hard bans

When you invent the look, none of these appear, ever. They are the fastest tells of generated work, and this skill exists to make films that don't look generated. `lint-film.mjs` checks the tokens and styles for them, and the critics check the frames.
- **Words:**
  - eyebrow or kicker labels above a headline;
  - stacked taglines, and "Introducing…";
  - full sentences dumped at once: copy arrives as short fragments, one after another, with picture between them (§4, "Text flow");
  - text walls, and random filler text: decorative mono captions, fake metrics, labels nobody needs, lorem ipsum.

  Every word on screen earns its place.
- **Type:** serif typefaces, and italic or oblique styles, including a skew that fakes one. Use one clean, modern sans, plus a mono for code or numbers if the product needs one.
