a timeline editor for films made of code. every frame is a function of time, every scene is a file, and every change previews instantly. retime it, voice it, score it, ship it.
it even writes an AGENTS.md for your robots.
paste into claude code or codex. it installs shot and opens the studio. or by hand →
that's not a video. it's a shot film running live in your browser. drag the film strip, or clap for another take.
drag an edge and the scene slows down. drag it back and it speeds up. split at beats, freeze a frame, crossfade, reorder. nothing gets re-rendered, because nothing was ever rendered.
write a line, pick a voice, press generate. gemini 3.8 tts (or elevenlabs v3) reads it, paced toward the length of the clip on your timeline, and a pitch-safe stretch lands it on the frame. keep every take. swap whenever.
lyria writes a track timed to your sections, so it builds where the film builds. it ducks under the voice all by itself. or drop in your own and pretend you did it.
every project ships with an AGENTS.md. point any coding agent at the folder and it knows the scene contract, the timeline and the tools. press P on anything in the studio to copy a short prompt with the exact file and timing.
like a look? save it. templates keep the scenes, the styles and the cut, and never the audio. start the next film from the last good one.
headless chrome draws every frame, ffmpeg does the rest, and the mix you heard is the mix you get. a 37-second film takes about 15 seconds in draft. the kettle takes longer.
goal, audience, beats, draft voiceover. a brief template is waiting in every project.
the film-design skill has claude build one scene per file, pure functions of time, and hand back a zip.
file → new project → pick the design. retime, reorder, voice it, score it. or let an agent do it from the cli.
export an mp4, or bundle the film into one html file that plays anywhere, like the one at the top of this page.
everything you'd find on the back of the film can, if there were a film can.

paste it into claude code or codex. your agent installs shot, sets up voice if you want it, adds the film-design skill and opens the studio. then file → new project. that's the whole manual. (there is also a real manual.)
read the manual →or by hand, in three:
needs node 22.18+, google chrome and ffmpeg (brew install ffmpeg). gemini voice and music need an api key or gcloud adc.
