核心原因：你使用的是 macOS 源码部署，系统环境变量 PATH 中找不到 ffmpeg / ffprobe 可执行文件。pyVideoTrans 的预处理阶段会调用 ffprobe 读取视频信息，找不到就直接报错。

解决方案（按步骤执行）：

安装 FFmpeg（macOS 官方推荐带 libx264 等完整编解码的 tap 源，而非核心版）：
```
brew tap homebrew-ffmpeg/ffmpeg
brew install homebrew-ffmpeg/ffmpeg/ffmpeg
```
验证是否装好并能在 PATH 中找到：
```
which ffmpeg
which ffprobe
ffmpeg -version
```
若两条 which 命令都能输出版本路径，说明已就绪。
若第 2 步无输出，说明 PATH 未包含 brew 的 bin 目录，请将以下内容加入 ~/.zshrc（macOS 默认 shell）后执行 source ~/.zshrc：
```
export PATH="/opt/homebrew/bin:/usr/local/bin:$PATH"
```
你的是 Apple Silicon（arm64），brew 默认安装到 /opt/homebrew/bin。
关闭并重新启动 pyVideoTrans（必须重启进程才能重新读取 PATH）。
补充提醒：你的项目路径位于 /private/tmp/pynini-fix/pynini-2.1.6.post1/pyvideotrans，这是系统临时目录，非常容易在系统重启或清理后被删除，导致后续运行集体报错。强烈建议将源码克隆到普通用户目录（如 ~/pyvideotrans）后再 uv sync 启动。
另注意：你选择的翻译渠道为 Google(免费)，在中国大陆需科学上网，需在主界面对齐控制行右侧的「网络代理」填写 http://127.0.0.1:端口，否则后续翻译阶段还会失败。
