1. Collects the product name, value sentence, audience, three product moments, format and any authorized assets.
2. Writes a storyboard where each cut adds new information, then connects focused action, typography, multiple results or applications, overview and closing action.
3. Adapts the DOM/CSS landscape or Canvas portrait starter to the brief, with complete English/Chinese copy and independently composed scenes.
4. Renders stills and a deterministic H.264 MP4, optionally muxes the original tonal score, then records stream data and honest picture, motion and listening checks.

• It creates original vector, text and concept-interface scenes, not live product recordings, voiceover, actors or unverified product functionality.
• The tested starter can use its original tonal score or silence. Bind sound to visible actions, verify the final mux and do not use unrelated sandy or airy noise.
• The renderer proves the local source and export; it does not prove platform compression, publishing, audience demand or conversion.
• The landscape sample is a Useful Mint design concept; the portrait is a separate Echo workflow example, not the same film cropped. Modified open-source motion ports retain their licenses.

Three distinct briefs per tool from the extracted package, whose files match the local member-download test: an English landscape campaign, a 9:16 Chinese feedback SaaS and a difficult long-name Chinese landscape delivery workspace. Actual HTML, MP4, decoded frames and QA are retained.

An editable linear-launch-film folder with the Skill guide, storyboard guidance, landscape and portrait templates, motion recipes and source licenses, deterministic Chromium renderer, tonal score, export helper, runtime notes, visual system and quality checklist.
