Short Editing

One raw take in, one finished video out: video-agent/edits/short-<slug>/output/short-<slug>.mp4.

The engine ships in this skill folder (<skill> below): <skill>/engine/short.mjs. It is a deterministic canvas renderer driven by ONE file per short, source/spec.js. The design is a paper stage on top and the camera below, one accent color, springs that never overshoot, no pulse, no bounce. Everything runs on the creator's computer, macOS, Windows or Linux: Node 20+, ffmpeg, a Chrome (or the headless Chromium setup installs), whisper.cpp.

Read before writing a spec:

• references/shorts-codes.md: format, safe zones, hook and pace
• references/design-system.md: palette, motion, paper, what is forbidden
• references/scene-library.md: every scene and item, every parameter, the time keys
• references/music.md: the 8 beds, which fits which hook, where to start it
• references/style.md: the house rules of the edit
• examples/: real shorts made with this engine (spec, components, contact sheets). Open the one closest to the request before planning: it is the quality bar.
