browser-use 发布开源 AI 视频剪辑 Skill「video-use」

browser-use 团队推出面向 Codex、Claude Code 等 AI 编码智能体的开源 Skill「video-use」,让 LLM 通过 ElevenLabs Scribe 将音频转写为约 12KB 文本(含逐词时间戳、说话人分离、事件标记),仅在决策点调用 timeline_view.py 生成 PNG 帧图。技术流水线包括转写、打包、生成 JSON 格式 EDL、ffmpeg 渲染及最多 3 轮自评估。渲染关键细节:分段提取 + `-c copy` 拼接、30ms 音频淡入淡出、PTS 时移、字幕最后叠加、HDR 自动映射、竖屏缩放、两-pass loudnorm。动画支持 HyperFrames、Remotion、Manim 等引擎。项目附带 12 条硬规则确保生产正确性。
