记录一下我删除相机 SD 卡当中废片的工作流

字数：18765 阅读量：1535

采用 python 脚本实现（python3）。支持图片（JPG/ARW/HEIF 等）和视频（MP4 + 配套 XML 元数据）的筛选删除。

相关说明：

  1. Linux/mac 电脑，如果你是 windows 电脑那么脚本需要稍加改造
  2. 相机当中开启了拍摄的照片按照日期文件夹存储，这种功能，否则可能一个文件夹下的照片数量特别多，你需要维护一个特别长的 keep.txt
  3. keep.txt 当中的文件名可以是完整文件名，也可以不包含扩展名。
    a. 如果是完整文件名，那脚本就根据完整文件名匹配去保留/删除文件
    b. 如果只包含文件名 stem，没有扩展名，将匹配所有包含 stem 的文件名，进而执行保留/删除逻辑。比如 keep.txt 当中有这样一行 HDK09432 ，那这些文件 HDK09432.JPG, HDK09432.ARW, HDK09432.HEIF 都会被保留，这尤其适用于你开启了 JPEG/RAW 拍摄，那么一张图片会有两个文件
  4. 支持模拟运行，只需要在最后添加 --dry-run
  5. 支持的扩展名：.jpg .jpeg .png .arw .heic .heif .hif .dng .mp4 .xml
  6. 索尼视频的 XML 元数据文件会自动匹配对应的 MP4 主文件（如 C0054M01.XML 跟随 C0054.MP4 同进退），无需在 keep.txt 中单独列出

照片工作流

索尼 JPEG 照片扩展名是 JPG，RAW 拍摄文件扩展名是 ARW，HEIF 拍摄扩展名是 HIF (Apple 的 HEIF 照片扩展名是 HEIC)

视频工作流

索尼 A7C2 录制视频后，存储卡上的目录结构为 PRIVATE/M4ROOT/CLIP/。与照片不同，视频不按日期分子目录，所有日期的视频文件都平铺在同一个 CLIP/ 目录下，因此 keep.txt 会较长。不过首次维护好之后，每次拍摄后只需要在末尾追加新增的 clip 号即可。

每个视频片段会生成：

  • C0054.MP4 — 视频主文件
  • C0054M01.XML — 配套元数据文件（自动跟随 MP4 同进退）
