Chữ tập hợp: bốn kiểu

Mọi thứ trên trang này đều có bản máy đọc. Đưa agent link JSON, hoặc thêm MCP server gimgs rồi bảo nó tìm motion template.

1. Tải JSON — trong đó có công thức cảnh quay (timing, easing, bảng tham số, lỗi hay gặp) và toàn bộ source TSX.
2. Clone repo video-shotcraft; component import fixture chung từ demos/_fixtures và helper từ assets/lib.
3. Đăng ký component thành <Composition> trong project Remotion rồi render bằng `npx remotion render`, hoặc dựng lại công thức bằng engine của bạn.

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

git clone https://github.com/Vincentwei1021/video-shotcraft
# component: demos/typography/type-assembly-moves/LetterformDriftAssembly.tsx, demos/typography/type-assembly-moves/SplitTextStagger.tsx, demos/typography/type-assembly-moves/TextOnPath.tsx, demos/typography/type-assembly-moves/TrackingExpandReveal.tsx
npx remotion render <CompositionId> out.mp4

claude mcp add --transport http gimgs https://gimgs.net/mcp
# then: search_motion_templates / get_motion_template("type-assembly-moves")

Use the video-shotcraft shot recipe "Chữ tập hợp: bốn kiểu" (Remotion composition, Apache-2.0) published on gimgs.net.
Recipe JSON (prompt = timing/easing/parameter table/pitfalls, files = TSX source): https://gimgs.net/motion/type-assembly-moves.json
Raw TSX: https://gimgs.net/motion/type-assembly-moves/template.html
Repository: https://github.com/Vincentwei1021/video-shotcraft  (component: demos/typography/type-assembly-moves/LetterformDriftAssembly.tsx, demos/typography/type-assembly-moves/SplitTextStagger.tsx, demos/typography/type-assembly-moves/TextOnPath.tsx, demos/typography/type-assembly-moves/TrackingExpandReveal.tsx; imports demos/_fixtures and assets/lib)
Spec: 1920x1080, 30 fps, 4.39s

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/type-assembly-moves/LetterformDriftAssembly.tsx, demos/typography/type-assembly-moves/SplitTextStagger.tsx, demos/typography/type-assembly-moves/TextOnPath.tsx, demos/typography/type-assembly-moves/TrackingExpandReveal.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.
