cinetic

Cinematic launch films and motion design from code, directed by your coding agent.

Kiln: a 25-second launch teaser that an agent branded, directed, scored and rendered from a two-sentence brief. The GIF is an excerpt; click it to download the full 1920x1080, 60 fps MP4 with sound (7 MB).

cinetic (cinema + kinetic) is an agent skill that makes your coding agent direct a short film instead of arranging animation components.

• Idea first. Before any code, the agent writes three concepts through different lenses, tests them, and picks one story device the film owns.
• 273 techniques, drawn at random. A library of measured moves in 14 categories, each with a build recipe and timing at 60 fps. pick.py draws the film's plan, weighted for its format and energy, so two films don't share the same fade-up, push-in and end card.
• Its own brand. The look comes from three personality words, so a calm notes app and a fast CI tool don't end up looking alike.
• Calm, with words in fragments. Copy arrives a few words at a time, split around what the product does ("here is the newest" → the product → its name), with readable holds that drift instead of freezing and stretches of pure picture between. The fragment grammar comes from a frame-by-frame study of eight professional films; a crisp profile is there when a brief asks for energy.
• One beat grid, measured sound. timeline.ts drives the picture, the soundtrack and the QA scripts, so every hit lands on its frame. The effects come from an earshot sound kit: sounds designed in code and rendered with measured sync points, one soft sound per text fragment, one clean element on the lockup. Typing, clicks and ticks follow measured norms of top-tier launch films: soft, short and mostly left to the picture.
• Finished and measured. True motion blur, no banding, BT.709 and a sync-checked mux, then pixel forensics, an audio-sync audit, contact sheets and critic passes against a ship gate.
• No generated look. Hard bans, enforced by a linter and the critics, keep out the looks that mark a video as generated. A brand you supply always wins.

It builds with Remotion (React) by default, or HyperFrames (HTML and GSAP).

Quick start

npx skills add Leonxlnx/cinetic

Then ask your agent for a film, for example: "Make a 20-second launch teaser with sound for our database branching tool. Invent the brand." It works with Claude Code, Codex, Cursor and the other agents the skills CLI supports.

Before the first film, check your machine with a first test render. It needs Node 22+, ffmpeg 6+, Python 3.11+ and a headless Chromium; see Requirements.

Quire Streaks. A 12 s vertical video for Reels and TikTok, in the brand the brief supplied. A blue thread stitches each day's pages into the Streaks screen, one rising note per stitch. On Sunday at 11:41 pm the thread hangs loose until one tap on Log pulls it tight, and the week gathers into a quire, the bookbinding word behind the name. Download MP4 (1080x1920, sound, 1.4 MB)

Ledgerly Auto-Split. A 10 s silent loop for a landing page. The bill starts split evenly at 53.55 each; Auto-Split tags each line with who ate it, fans the receipt out into four and trims each copy to that friend's dishes, shared ones divided only among the people who shared them. "Jonas only had salad." Download MP4 (1920x1080, loop, 2 MB)

Halden. A 6 s logo sting for a calm note-taking app, mixed at −16 LUFS, plus four ProRes 4444 alpha versions (held and cleared, for light and dark footage). The app's text cursor settles into a dot, and the h draws its arch over it like a fermata, the musical sign for "hold". Download MP4 (1920x1080, sound, 0.3 MB)

All four films were made by an agent with development snapshots of cinetic 1.0.0, in evaluation rounds 6 (Kiln) and 7 (the others), from the one-paragraph briefs below, the same briefs used in the evaluation. The brands are invented, except where the brief supplied one. Clicking a GIF downloads its MP4. The films live on the repo's media branch, so installs stay small.

The four briefs, word for word

Kiln launch teaser

Invent the brand for Kiln (a build cache that makes CI runs finish in seconds) and make a 25-second launch teaser with sound for our announcement on X. It should feel like a well-funded company shipped it, not a template.

Quire Streaks vertical video

Our reading-tracker app Quire is shipping Streaks next week. Make a 12-second vertical product video (1080x1920, for Instagram Reels and TikTok, with sound) showing how a reading streak builds over a week. Use our brand: ink #1B1B1F, paper #FBF7F0, accent #3E7BFA, typeface Manrope.

Ledgerly feature loop

Make a 10-second looping feature animation for the landing page of Ledgerly, a shared-expenses app. It should show the new Auto-Split feature splitting a dinner bill between four friends. 1920x1080, it has to loop seamlessly and work without sound (it autoplays muted on the site).

Halden logo sting

We're launching Halden, a calm note-taking app. Design the logo and make a 6-second logo sting with sound that we can put at the start of our videos, plus a transparent version for our editors.
