What it does

Motion Video is an agent skill from bestagentkits/motion-video-skill. Produce beat-synced 1080p motion-graphic videos in HyperFrames (HTML + GSAP) with an AI voice-over, Vietnamese karaoke captions, SFX and generated music, in one of two proven styles (glass keynote or Spider-Verse-style comic). Use when the user asks for a launch/release/feature video, motion graphic, animated explainer or promo clip, or a restyle of an existing one.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 28 other files, including scripts, reference files and assets (for example `assets/templates/data/cues.example.json`, `assets/templates/data/music-arrangement.example.json` and `assets/templates/data/music-plan.example.json`).

It sits in Media & Creative, covering Motion graphics, Text to speech and voice and Web animation and motion. It works with HeyGen, GSAP, OpenAI and ElevenLabs. The repository describes itself as: Agent skill that produces beat-synced 1080p motion-graphic videos in HyperFrames (HTML + GSAP) with an AI voice-over, karaoke captions, SFX and generated music. MIT. The licence is MIT.

When your agent uses it

  • The user asks for a launch/release/feature video
  • Animated explainer
  • A restyle of an existing one

Example prompts

  • “/motion-video”

Requirements

  • Python 3
  • Node.js

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Pin the outcome before touching files: topic and sources, style (one of the
  2. Create assets/videos// (never overwrite a finished edition) and a plan
  3. Follow references/production-pipeline.md step by step. Each step writes a
  4. Get the music right with references/audio-and-beat-sync.md: fit the grid,

  6. Finish only when every check in "Done when" passes; report measured numbers,

What it can do on your machine

Read from SKILL.md and the folder at commit a73702b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (JavaScript, from the files we listed), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • x.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Motion Video loads about 1.5k tokens when it runs, and up to ~7.7k if it reads all its reference files. Until then it costs about 95 tokens; SKILL.md has 598 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~95
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~7.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Motion video

Make a 1920×1080 30 fps motion-graphic video where the scene cuts land on the music's beats, reveals land on spoken words, and the audio is broadcast-clean. The workflow is fully scripted: facts → script → multix audio → forced alignment → beat grid → bar-spliced music → timeline + mix → HTML composition → lint/check/snapshot → render → remux → social encode.

Two finished editions show what each style should feel like. Their working projects are deliberately not bundled here: the generated voice-over, music and SFX are large and provider-licensed. Study the published demo, then build every new video from assets/templates/index-skeleton.html plus the style reference.

StyleStyle referencePublic demoFeel
Comic multiversereferences/style-comic-spiderverse.mdDewee v3.34 comic edition, the 151 s social encodeloud, playful, hand-made
Glass keynotereferences/style-glass-keynote.mdthe 144 s edition of the same releasepremium, calm, clear

Scope

This skill handles:

  • New videos in either style, restyles of an existing video as a separate project, and partial reworks (new music, re-timed drops, re-mix, re-render, social encode).
  • Audio through the multix CLI: Gemini TTS voice, ElevenLabs SFX, ElevenLabs Music composition plans, ElevenLabs forced alignment.

This skill does NOT handle:

  • Generative text-to-video footage (use multix Seedance/Veo directly).
  • React/Remotion compositions or generic HyperFrames questions (use the hyperframes or remotion skills).
  • Publishing to social accounts: produce the file and let the user post it.

How to work

  1. Pin the outcome before touching files: topic and sources, style (one of the two, or a new one derived from them), duration, voice language (English VO + Vietnamese captions by default), ending, signature. Ask only if the style or the facts source is unknown.
  2. Create assets/videos/<slug>/ (never overwrite a finished edition) and a plan under plans/ following the repo convention. Copy the templates from assets/templates/ of this skill: scripts/*.mjs, data/*.example.json (rename to .json), hyperframes.json, index-skeleton.html as index.html, plus scripts/fit-beat-grid.py.
  3. Follow references/production-pipeline.md step by step. Each step writes a file the next one reads, so do not reorder them.
  4. Get the music right with references/audio-and-beat-sync.md: fit the grid, splice bars so the drops land where the script needs them, verify the splice, and measure the voice/music balance.
  5. Build index.html with references/composition-contract.md and the chosen style reference, starting from assets/templates/index-skeleton.html. When a scene type repeats (stats, diagrams, charts, terminal, graph, outro), follow the demo's choreography for that scene instead of inventing a new one.
  6. Finish only when every check in "Done when" passes; report measured numbers, not impressions.

Keep credentials inside multix's own config. Never print API keys or copy them into project files, plans or reports.

Done when

  • hyperframes lint and check pass; snapshots of every scene were reviewed.
  • verify-arrangement.py reports every segment within ±2 ms and measure-mix-balance.py shows the music ~4–6 dB under speech.
  • ffprobe: 1920×1080, 30 fps, expected duration, AAC 48 kHz stereo; ebur128 ≈ −14 LUFS with peak ≤ −1 dBFS; blackdetect finds nothing outside fades.
  • build-timeline printed no clip/overlap/missing-word warnings.
  • On-screen facts trace to the sources collected in step 1.

Resources

  • references/production-pipeline.md: every command from scaffold to social encode and studio preview, plus the rebuild table.
  • references/audio-and-beat-sync.md: voice, SFX cues, music plans, bar-splice arrangement, anchors, mix numbers and the ducking pitfall.
  • references/composition-contract.md: TIMING shape, helpers, determinism, scene windows, captions, mascot, renderer limits, signature.
  • references/style-glass-keynote.md / references/style-comic-spiderverse.md: tokens, fonts, layers, components, transitions and caption look per style.
  • scripts/fit-beat-grid.py <music> [--min-bpm N --max-bpm N]: BPM, BEAT0 and a per-bar kick/energy table.
  • scripts/verify-arrangement.py <project> [--tolerance-ms 2]: splice lag per segment; exits 1 on drift.
  • scripts/measure-mix-balance.py <project>: music under speech vs in gaps, from build-timeline.mjs --stems.
  • scripts/tests/: python -m unittest discover -s scripts/tests (needs ffmpeg, numpy, scipy).
  • assets/templates/: project scripts (generate-audio-assets, align-voiceover, arrange-music, build-timeline), example data files and the composition skeleton.
