Video & Animation

Use when a source must become a narrated explainer video.

Turn a weekly changelog .md into a finished branded changelog video (square 1080, ~45-60s, Annie VO, animated brand background, mock-UI visualizations, lowkey captions). Use when the user provides a changelog/digest markdown and wants the weekly video, or says "changelog video". Self-contained — fonts, background, lexicon, and scripts ship in this skill.

Overlay doctrine for the embedded-captions workflow — the caption MODEL (drop / rail / embed) and the rule that captions are an OVERLAY composited on top of the film, never a reserved bottom band you shift content up to avoid. Load when adding captions/subtitles to a talking-head or launch video, when deciding whether a phrase should be dropped, ride the verbatim rail, or be promoted to a scarce embedded climax, when laying out a composition that will carry captions (do NOT reserve a keep-out band), or when centering a composition on the true frame center under captions. Quotes the rail+embed model from embedded-captions and constraint #13 (captions overlay, keep-out band retired) from the product-launch-video scene agent. Applies ON TOP of embedded-captions.

Turn the user's footage plus copy (文案) into a finished 16:9 Chinese 财经/知识 explainer short video — rewrite the script around a strong hook, fact-check it, voice it with Volcano Ark Agent Plan TTS (默认 解说小明2.0), cut the footage with canvas motion graphics, auto-pick BGM and sound effects from the user's own libraries, mix, QA and deliver. Use whenever the user gives a video file (usually with copy or a topic) and asks to 精剪/剪成讲解短视频, 做动效, 合成配音, 横屏16:9, or to choose bgm/音效 from their folders.

Plan an explainer-video series from a directory of coursework notes — decompose into videos (proving nothing is dropped), retitle and curate, write the narration, synthesize the audio, author the visuals, then render and assemble the finished cut. Use when the user wants to turn structured coursework notes into explainer videos.

Assemble one video from its segments — render each window silent, concatenate, mux the narration once, and verify. Stage 8 of explainer-video-from-coursework.

Synthesize narration and build the measured timeline for one video. Stage 4 of explainer-video-from-coursework — the one-shot TTS primitive.

Break a plan, spec, or the current conversation into a set of tracer-bullet tickets, each declaring its blocking edges, published to the configured tracker (edges as text in one file per ticket locally, or native blocking links on a real tracker).

Render one scene config over one time window to an MP4 (or a handful of QA stills). Stage 7 of explainer-video-from-coursework — the render primitive.

Turn the current conversation into a spec and publish it to the project issue tracker: no interview, just synthesis of what you've already discussed.

Set up and apply the project's brand guidelines for the video. Writes or reads BRAND.md and the brand/ folder (logo, fonts, palette, reference assets), generates design.json (fonts, colours, grain, logo) from them, checks them with check.py, and records the brand rules in HANDBOOK.md. Use when the user mentions brand guidelines, BRAND.md, a logo, a palette, brand colours, fonts for the video, brand assets, or design.json.

Write and validate the spoken narration for one explainer-video. Stage 3 of explainer-video-from-coursework; run it alone to (re)write a video's script.

Use when doing ANY task involving Supabase. Triggers: Supabase products (Database, Auth, Edge Functions, Realtime, Storage, Vectors, Cron, Queues); client libraries and SSR integrations (supabase-js, @supabase/ssr) in Next.js, React, SvelteKit, Astro, Remix; auth issues (login, logout, sessions, JWT, cookies, getSession, getUser, getClaims, RLS); Supabase CLI or MCP server; schema changes, migrations, declarative schemas, security audits, Postgres extensions (pg_graphql, pg_cron, pg_vector); debugging and troubleshooting errors or unexpected behavior on Supabase projects (HTTP errors, Postgres errors, RLS surprises, permission denied, schema cache issues, timeouts, Edge Function crashes, Realtime drops, Storage failures) and reading or querying logs (Logs Explorer, ClickHouse).

Author and iterate the animated visuals for one video's segments. Stage 5 of explainer-video-from-coursework; it re-invokes the audio stage when a beat needs a hold.

Generate YouTube chapters and English captions for one finished video. Stage 6 of explainer-video-from-coursework.

Retitle and curate the videos in an explainer-video plan — write enrichment.json and merge it. Stage 2 of explainer-video-from-coursework; run it alone to retitle an existing plan.

Decompose a coursework notes directory into an explainer-video plan and prove no content-bearing section is dropped. Stage 1 of explainer-video-from-coursework; run it alone to (re)plan a directory.

Turn a written script into a spoken WAV with Gemini TTS (gemini-3.8-flash-tts) using a prebuilt voice and an optional style direction. Use when the user asks for narration, a voiceover, text-to-speech, an audio version of a text, or a spoken sample of a script. Covers choosing a voice, preparing the transcript, and writing style directions.

Implement a piece of work based on a spec or set of tickets.

Make a showreel-grade product or feature launch video in code, for any product - a launch film, feature drop, teaser / countdown, kinetic-type announcement, UI-motion hero reveal, problem → solution, release roundup, before / after, integration, milestone, an Instagram Reel / TikTok / Shorts cut, or a lit-3D showreel. Learns the product from its site, codebase or a few answers, rebuilds its screens in HTML with fictional data, animates them on a beat grid with HyperFrames and Three.js (exact brand colours, bloom, real transitions), writes a royalty-free soundtrack, and renders a verified MP4 plus GIF. Use for "launch video", "feature announcement video", "promo for our new feature", "changelog clip", "teaser", "reel for our launch", "product video for my app".

Review the changes since a fixed point (commit, branch, tag, or merge-base) along two axes: Standards (does the code follow this repo's documented coding standards?) and Spec (does the code match what the originating issue/spec asked for?). Runs both reviews in parallel sub-agents and reports them side by side. Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to \"review since X\".

Turn a narration audio file plus its exact script into a polished, graphics-first, motion-designed educational video for children (pictures, characters and animation teach; on-screen text is minimal) in three age bands (0–3, 3–6, 6–9), in English, Hindi or mixed Hinglish. Uses a gated stage process: word-level forced alignment, sync-test video, learning and creative direction (series style bible plus per-video screenplay), Remotion engine and hero proof, then full renders. Outputs 9:16 for Reels/Shorts and/or the in-app player size. Use when the user wants a kids' learning video, explainer for toddlers or preschoolers, alphabet/numbers/colours/animals/varnmala video, educational Reel/Short, picture-led explainer, or says "check the folder" in a folder containing narration audio and a script.

>- Raise any motion-graphics or launch/promo video to agency-grade quality — the bar set by studios like Buck, Giant Ant, Ordinary Folk, Oddfellows, ManvsMachine and Territory, and designers like Jorge Canedo, Andrew Vucko, Ash Thorp and Emanuele Colombo. Load this BEFORE writing or reviewing any animation (kinetic type, stat/number reveals, logo stings, product/SaaS launch films, UI-in-motion, explainers), especially in HyperFrames/GSAP. It carries a studio field guide, the motion-principles canon, timing & easing numbers, a transitions toolkit, frame-accurate sound design, the Apple/UI motion register, texture/depth, a production method, an anti-slop checklist, and a hard pre-flight gate. Triggers: "make it really good / high-end / like a real agency", "this looks cheap/flat", motion polish, launch-video craft review.
