Why it's ranked here

The instructions are unusually concrete for a creative skill. Videos are capped at 15 to 25 seconds, readable text must hold for roughly 0.3 seconds per word, at least one scene has to show real product UI, and nine planning questions must be answered before anything is drawn. The project-reading step forbids carrying secrets, internal URLs or personal data into a video meant for public posting. It is MIT licensed and installs into Claude Code, Codex and any agent the open skills installer supports. The cost is a heavy toolchain on the classic path and output quality that rests on how well the model follows long prose.

What's good

Small details show real publishing experience. The delivery step picks the strongest settled frame as a poster and swaps it in as the very first frame, because Slack, X and Discord build thumbnails from frame zero and ignore cover-art metadata; duration and audio sync stay unchanged. Beat sync is optional and bounded: an included script scores each beat on onset strength, contrast, loudness and bass, and the instructions allow only one to three hard locks per video. The planning guide warns that revealing a line of text on every beat at fast tempos outruns reading, and says to snap to every other beat instead. Voiceover is strictly opt-in.

Tradeoffs

The classic path needs Node.js 22 or newer, FFmpeg on the system path and the Hyperframes command-line tool; the optional beat analysis adds Python 3.11 with librosa, numpy and scipy. The automatic switch to the slim variant is triggered by the model recognising that it is Opus 5.5, so the path taken depends on self-identification. The inspection step reads a landing page and its stylesheet first, so a command-line tool or library has less to show and falls back to a text-led video. Cross-agent discovery relies on symlinks, which on Windows need Developer Mode or administrator rights. Nothing beyond the renderer's own check verifies the result.

How to use it well

Best for someone who just shipped a web app with a real interface and wants a short clip for X, LinkedIn or a group chat without opening a video editor. Run it with defaults first, then steer with a tone preset such as deadpan or cinematic, or a freeform phrase, and choose vertical format for phone feeds. Preview before the final render and use draft quality while iterating. It does not cover tutorials, long product demos or narrated explainers: the length cap holds even with voiceover on, and headless projects give it little to show.
