Zoom đấm áp sát mục tiêu

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/crash-zoom-punch.json

git clone https://github.com/Vincentwei1021/video-shotcraft
# component: demos/camera/crash-zoom-punch/CrashImpactReal.tsx, demos/camera/crash-zoom-punch/CrashZoomReal.tsx
npx remotion render <CompositionId> out.mp4

claude mcp add --transport http gimgs https://gimgs.net/mcp
# then: search_motion_templates / get_motion_template("crash-zoom-punch")

Use the video-shotcraft shot recipe "Zoom đấm áp sát mục tiêu" (Remotion composition, Apache-2.0) published on gimgs.net.
Recipe JSON (prompt = timing/easing/parameter table/pitfalls, files = TSX source): https://gimgs.net/motion/crash-zoom-punch.json
Raw TSX: https://gimgs.net/motion/crash-zoom-punch/template.html
Repository: https://github.com/Vincentwei1021/video-shotcraft  (component: demos/camera/crash-zoom-punch/CrashImpactReal.tsx, demos/camera/crash-zoom-punch/CrashZoomReal.tsx; imports demos/_fixtures and assets/lib)
Spec: 1920x1080, 30 fps, 4.05s

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/camera/crash-zoom-punch/CrashImpactReal.tsx, demos/camera/crash-zoom-punch/CrashZoomReal.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.
