Ảo thuật lật bài xuất hiện

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/magician-card-flourish.json

git clone https://github.com/Vincentwei1021/video-shotcraft
# component: demos/opening/magician-card-flourish/MagicianCardFlourish.tsx
npx remotion render <CompositionId> out.mp4

claude mcp add --transport http gimgs https://gimgs.net/mcp
# then: search_motion_templates / get_motion_template("magician-card-flourish")

Use the video-shotcraft shot recipe "Ảo thuật lật bài xuất hiện" (Remotion composition, Apache-2.0) published on gimgs.net.
Recipe JSON (prompt = timing/easing/parameter table/pitfalls, files = TSX source): https://gimgs.net/motion/magician-card-flourish.json
Raw TSX: https://gimgs.net/motion/magician-card-flourish/template.html
Repository: https://github.com/Vincentwei1021/video-shotcraft  (component: demos/opening/magician-card-flourish/MagicianCardFlourish.tsx; imports demos/_fixtures and assets/lib)
Spec: 1920x1080, 30 fps, 4.25s

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).

// magician-card-flourish v6 —— 批次 15（无截图，用户意见即全部真相）：
// 用户意见（逐字）"这个光需要带点辉光，0.8秒就行；然后十字星应该做成更符合
// 光学实感的，现在太5毛特效了；卡片最开始出来的时候，要做成那种弹射出来的
// 效果，就是刚开始弹射出来速度慢，然后划弧线的过程减速"
// ① 光效段 1.5s→0.8s（24f），辉光加厚（三层柔晕包裹）；
// ② 十字星光学实感重做：等宽矩形条改衍射尖峰（径向渐变楔形——越远越细
//    且亮度指数渐隐），三层叠色（白细芯/蓝中层/宽淡外层近似色散），
//    旋转放慢（24f 转 ~40°，真实星芒旋转是镜头效应，快了就假）；
// ③ 弹射出场：slow-in → burst → decelerating arc（起飞先慢速蓄力挤出，
//    急加速弹射，弧线段整体减速抵达中心硬定格）。
// v5 其余保留：中心极远飞出+13 圈自旋+94% 定格+sheen 扫光。总长 141 帧。

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/opening/magician-card-flourish/MagicianCardFlourish.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.
