Who it is forA founder or product marketer preparing an announcement post who needs a polished teaser without a video team.

The problemLaunch films usually need a designer, an editor and a sound person, and a template-based video looks generic.

The outcomeA rendered 1920x1080, 60 fps MP4 with sound, built from a two-sentence brief with an invented brand.

What you need first

  • Node 22+
  • ffmpeg 6+ with libx264 and ffprobe
  • Python 3.11+ with the listed Python packages
  • A headless Chromium
  • A coding agent such as Claude Code, Codex or Cursor

Steps

  1. Run npx skills add Leonxlnx/cinetic to install the skill.
  2. Check your machine with the first test render in docs/setup.md before the first film.
  3. Ask your agent: "Make a 20-second launch teaser with sound for our database branching tool. Invent the brand."
  4. Let the agent run python3 scripts/pick.py --format launch --energy high --seconds 25 --json out/qa/picks.json to draw its techniques.
  5. Review the rendered MP4 and the QA output in out/qa before you publish.

Prompt for your agent

Using the cinetic skill in the Leonxlnx/cinetic repo, make a 25-second launch teaser with sound for <product name>, using the brief <one-paragraph brief>. Render a 1920x1080 MP4 and report the seed printed by pick.py. Verify that the QA audio-sync audit and the ship gate pass before you hand over the file.

Caveat. The README says the first film needs Node 22+, ffmpeg 6+, Python 3.11+ and a headless Chromium, so setup is the main effort before the film itself.
