我想我在游戏中很少，但今天在研究同一主题时，我发现MacOS现在附带avconvert：

AVCONVERT(1)              BSD General Commands Manual             AVCONVERT(1)

NAME
     avconvert -- movie conversion tool

SYNOPSIS
     avconvert [-hvq] --p <preset_name> --s <source_media> --o <output_movie>

DESCRIPTION
 avconvert can be used to compress video media to different types for sharing on the
 web or loading onto devices.

 -h       prints usage information and available presets

 -v       sets the console output to verbose

 -q       sets the console output to quiet

 -prog    shows progress during the export (default with -v)

 -p | --preset name
          converts the source media to an output file using the specified preset. Use
          --listPresets to get the full list. Common presets are:

          PresetAppleM4VCellular
          PresetAppleM4ViPod
          PresetAppleM4VWiFi
