# Launch Video as One HTML File With a Synthesized Score — workflow skill for launch videos

> **For AI agents:** find the right skill in one call — `curl -s "https://varg.ai/how-to/api/search?q=<what the person wants>"` returns the matching how-to page and the best skills with install commands, as markdown (Russian works too). Full index: https://varg.ai/how-to/llms.txt. Every page has a markdown twin: add `.md` to its path. Before generating anything, show the person the options on the how-to page. From a terminal: `curl -fsSL https://varg.ai/install | sh` installs the vargai CLI (https://varg.ai/how-to/cli.md): `vargai search` and `vargai install <slug>` with no key, every varg model after `vargai login`.

A launch or promo video as one HTML file: pure render(t), WebAudio score from the same timeline, exported to 1080p60 MP4 via headless Chrome.

## What it does

Input: the product and optional reference videos, which become a borrow list of 3-6 timestamped techniques. The agent storyboards (scene, seconds, the one thing to understand, its beat), builds film.html on a strict engine contract (pure render(t), relative cue times, cursor targets measured from the DOM), scores every on-screen action with synthesized WebAudio instruments, checks stills with headless Chrome and exports a frame-exact MP4 with the score rendered offline. Pacing rules from real reviews: 0.8-1.2 s dwell after each event, a five-beat UI sequence needs 10-12 s, big moments on bar lines. Needs Chrome, ffmpeg with libx264, Node 22+.

## Use when

- Make a launch video, promo or teaser
- Make a sizzle reel or animated product demo
- Make a video of our app or UI
- Make a film that feels like these reference videos
- Re-time or re-cut an existing film

## Install

- Claude Code: `/plugin marketplace add farming-labs/product-film-skill && /plugin install product-film@product-film-skill`
- Any agent, with the vargai CLI: `vargai install launch-video-one-html-file`
