在视频存放目录进入 git-bash 环境，使用 ls 和 awk 命令组合生成批量的 ffmpeg命令行
ls -1 *.MOV | awk '{print "ffmpeg -y -i " $1 " -c:v libx265 -crf 30 " $1 "_HEVC.mp4"}'
- 使用这个命令后，就得到了批量的 ffmpeg命令行
ffmpeg -y -i 20250225072548_001908AAN.MOV -c:v libx265 -crf 30 20250225072548_001908AAN.MOV_HEVC.mp4

FFMpeg 把这些 MOV 转成 Hevc格式后，文件体积从 950M 压缩到了452M
最后使用一个 mp4boxa 这个工具把多个mp4文件合并成一个文件，方便上传B站
