What's inside
One skill, ultramotion:
- 90 effects in
skills/ultramotion/effects/ — one shot each: a neon sign switching on, a datamosh cut, a rolling number, a karaoke wipe. Ask for the shot ("that neon flicker-on with my bar's name"), or browse them on ultramotion.ai/effects.
- 65 templates in
skills/ultramotion/templates/ — each a folder with the pages to start from and what to change. Ask for one by what you're making ("a neon sign for my bar", "a bar chart race of Super Bowl wins", "a lyric video for my song"), or browse them with their videos on ultramotion.ai.
- 21 engines in
skills/ultramotion/lib/, each with a guide, for making your own pieces when no template fits:
| Engine | | |
|---|
| Liquid Glass | Apple-style glass that pops, stretches, merges and bends text | 9:16, 120 BPM |
| Kinetic Type | Heavy condensed type slamming in on the beat, colour-block cuts | 9:16, 128 BPM |
| Hand-drawn Explainer | Whiteboard, notebook or chalkboard explainers written stroke by stroke (real stroke order for Chinese), with a camera across the board and its own music | 9:16 |
| Variety Captions | Variety-show pop words, bursts, stamps and sound effects on your own footage, placed around the face | 9:16, on your footage |
| Light Particles | Up to 1.6M glowing particles that gather into products, vehicles, towns and titles, build up in order and light up | 9:16, WebGL2 |
| Flat Explainer | Kurzgesagt-style narrated explainers: the voice-over is timed word by word and things appear as they are named | 9:16, narrated |
| Painterly | Van Gogh / Loving Vincent-style oil paintings that move: thick strokes following the form, impasto lighting, the camera walking into the picture | 9:16 |
| Ink Wash | Chinese ink painting in the manner of the Shanghai Animation Film Studio: ink spreads across rice paper, the picture keeps living, scenes dissolve through the ink, a carved seal | 9:16 |
| Event Replay |
render.py turns a page into an mp4 with its sound; sound.py plays the music on sampled instruments and makes the sounds of the picture.
Requirements
ffmpeg; Python with playwright, Pillow, numpy, scipy and soundfile; Playwright's Chromium or an installed Google Chrome (WebGL2 for the GPU engines); fluidsynth for music on sampled instruments (brew install fluid-synth / apt install fluidsynth — the free GeneralUser GS soundfont downloads itself on first use). Variety Captions finds faces with Apple Vision on macOS or MediaPipe elsewhere; Flat Explainer voices the script with edge-tts or aligns your own recording with Whisper; Karaoke times lyrics with Whisper.
Benchmark
Style pages on ultramotion.ai show the same prompt run without and with the skill — Claude Code (Sonnet 5.5) and ChatGPT Codex (GPT-6.1-Sol), plus WorkBuddy (MiniMax M2.7) and 豆包 for some styles.
