What it does

This skill teaches an AI agent to shrink video files, mainly macOS screen recordings, using a command-line tool called quietshrink. It uses the Mac's dedicated video encoder instead of the main processor, so the job runs faster and the computer stays quiet, and it aims to cut file size substantially (the SKILL.md claims 70-90%) while keeping the picture visually near-identical. It also lets the agent inspect a video's codec, resolution and length before compressing it.

Great for

  • Mac users on Apple Silicon (M1 to M4) who need to send a screen recording through chat, email or GitHub
  • People who want smaller video files without visible quality loss
  • Anyone who wants an agent to handle video compression with a single request

Skip it if

  • Camera footage, vlogs or other non-screen video, because the SKILL.md says savings will be much smaller there
  • Intel Macs or other systems, since the skill notes that non-Mac use falls back to less efficient software encoding
  • Situations where a compressed copy must be byte-identical or lossless to the original, since even the default preset is lossy

Try asking

  • “Compress this screen recording so I can email it to my team”
  • “Shrink ~/Desktop/demo.mov to a small file for a GitHub issue”
  • “Check the resolution and duration of this video before compressing it”
  • “Make the smallest possible version of this recording for Slack”

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Run the doctor command first to confirm ffmpeg and the hardware encoder are available
  • Use the default transparent preset for anything important; choose tiny only when small artifacts are acceptable
  • Keep the original file until you have checked the compressed output visually
