# Render B-roll Animation / 动画 B-roll ## When to use / 何时使用 Generic motion graphics, kinetic typography, logo reveals, etc. Hyperframes renders HTML to MP4 locally. 通用动画图形、动态文字、Logo 揭示等。Hyperframes 在本地把 HTML 渲染为 MP4。 ## Inputs / 输入 - `workspace/broll/plan.json` row (or `--id`). - `templates/broll/animation/*.html` (Hyperframes templates). ## Output / 输出 - `workspace/broll/broll_<id>.mp4`. ## Steps / 步骤 1. Pick template by `style` field (or default). 2. Substitute `{{prompt}}`, `{{duration}}`, colors from `config/brand.yaml` into HTML. 3. Invoke Hyperframes via `mcp__hyperframes__render` (it spawns headless Chromium → MP4). 4. Validate output duration and resolution; transcode to H.264 if needed. ## Examples / 示例 ``` claude run render-broll-animation --id 04 --style kinetic-type ``` ## Failure recovery / 失败回退 - If Hyperframes unavailable, fall back to `render-broll-animation`'s minimal canvas template via ffmpeg drawtext. - If render time > 2× duration, lower fps to 30 and retry once.
