+### 从 .mov 转码为 .mp4（推荐）
+
+剪辑软件常导出 **.mov**，浏览器兼容性差；前台统一使用 **`.mp4`（H.264+AAC）**（见 `src/data/promotionVideos.js`）。
+
+**服务端自动转码（推荐，线上）**  
+上传到 **`promotion/...`** 的 **`.mov`** 时，API 容器/主机需在 PATH 中有 **`ffmpeg`**（`server/Dockerfile`、`Dockerfile.run` 已 `apk add ffmpeg`）。服务会：
+
+1. **上传后**：异步将 `.mov` 转为同名 `.mp4`，删除原 `.mov`，并更新 `site_assets` 中路径与大小。  
+2. **启动后约 3 秒**：扫描 `uploads/sites/*/promotion/**/*.mov`，对遗留文件补转码并写库。
+
+环境变量 **`SKIP_PROMOTION_TRANSCODE=1`** 可关闭转码（无 ffmpeg 时避免报错日志）。
+
+部署 API 镜像更新后请执行 **`docker compose build api`**（或等价命令），确保运行环境含 ffmpeg。
+
+**仅静态站、无 API 时（本地可选）**  
+可在 `web/` 执行 `npm run transcode`（见 `scripts/auto-transcode-promotion.mjs`），或仓库根目录 `scripts/transcode-promotion-videos.sh` / `.ps1`。
