让 Agent 用 FFmpeg 剪视频，它上来就猜帧率、乱选编码，明明只需要流复制的活也重新编码一遍，完了不看结果就说搞定。 ffmpeg-skill 给 Claude Code、Cursor、Codex 装上一个视频编辑器，21 个工具全在本机跑 FFmpeg，不上云不要 key。 流程定死了，先探测文件再动手，能无损流复制的就不重编码，做完把结果再探测一遍，画面变了还出一张缩略图自己看。 GitHub：http://github.com/kajisho5/ffmpeg-skill 剪切拼接、去静音跳切、适配时长和比例、字幕和卡拉 OK 字幕、水印和字幕条、HDR 转 SDR、音频降噪、多机位对齐、响度标准化，都有。 跟它说「把 interview.mp4 这两段留下，剪成正好 60 秒的 Reels」，它会剪、裁 9:16、导出、按平台规格检查，最后报一句时长分辨率。 每个工具都能先只打印命令不动文件，原文件从不覆盖，同一套工具也能当 MCP 用。手里有素材又懒得背 FFmpeg 参数的，装上让 Agent 干。
