Typewriter: two moods

Everything on this page is also machine-readable. Point your agent at the JSON, or add the gimgs MCP server and ask it to search motion templates.

1. Fetch the JSON — it holds the shot recipe (timing, easing, parameter table, pitfalls) and the full TSX source.
2. Clone the video-shotcraft repo; the component imports shared fixtures from demos/_fixtures and helpers from assets/lib.
3. Register the component as a <Composition> in a Remotion project and render with `npx remotion render`, or re-implement the recipe in your own engine.

curl -s https://gimgs.net/motion/typewriter-moves.json

git clone https://github.com/Vincentwei1021/video-shotcraft
# component: demos/typography/typewriter-moves/TerminalTypewriter.tsx, demos/typography/typewriter-moves/TypewriterErrorRetype.tsx
npx remotion render <CompositionId> out.mp4

Use the video-shotcraft shot recipe "Typewriter: two moods" (Remotion composition, Apache-2.0) published on gimgs.net.
Recipe JSON (prompt = timing/easing/parameter table/pitfalls, files = TSX source): https://gimgs.net/motion/typewriter-moves.json
Raw TSX: https://gimgs.net/motion/typewriter-moves/template.html
Repository: https://github.com/Vincentwei1021/video-shotcraft  (component: demos/typography/typewriter-moves/TerminalTypewriter.tsx, demos/typography/typewriter-moves/TypewriterErrorRetype.tsx; imports demos/_fixtures and assets/lib)
Spec: 1920x1080, 30 fps, 4.89s

1. Read the JSON and follow its "prompt" section (when to use, intention, parameter table, known pitfalls).
2. Adapt it for: <describe what you want>.
3. Either clone the repo, register the component as a <Composition> in a Remotion project and run npx remotion render <CompositionId> out.mp4 — or re-implement the recipe in your own engine (HTML/WAAPI works: keep the same timing and easing).

1. Read the recipe
   Prompt = when to use, intention, parameter table with typical values and how each one feels, known pitfalls. Treat values as calibrated starting points.
2. Get the code
   tool: git
   git clone https://github.com/Vincentwei1021/video-shotcraft && cd video-shotcraft && npm install
3. Register + render
   tool: remotion
   npx remotion render <CompositionId> out.mp4 # component: demos/typography/typewriter-moves/TerminalTypewriter.tsx, demos/typography/typewriter-moves/TypewriterErrorRetype.tsx
4. Or re-implement
   Port the timing/easing from the recipe to HTML + WAAPI (gimgs motion contract) or any engine; keep the same segment windows and easing.
