SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It solves the problem of reducing large macOS screen recordings into shareable files without stressing your CPU or causing obvious visual degradation.

Core Features & Use Cases

  • Hardware-accelerated HEVC compression (Apple Silicon): Uses the Media Engine hardware encoder to make encoding fast and quiet.
  • Quality presets for different sharing needs: Choose tiny for maximum size reduction, transparent for visually lossless sharing, or pristine for near-archive quality.
  • Preflight and verification: Probe file details and run doctor to validate your environment before compressing. Use case: You recorded a long screen session on an M1/M2/M3/M4 Mac and need to email or upload it; compressing with the transparent preset keeps it visually lossless while cutting file size dramatically.

Quick Start

Run cli-anything-quietshrink compress -q transparent input.mov output.mov to shrink the recording while keeping it visually lossless.

Frequently Asked Questions about cli-anything-quietshrink

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I compress macOS screen recordings for email without losing visual quality?▼

You can compress macOS screen recordings for email while maintaining visual fidelity by using a visually lossless quality preset. This applies hardware-accelerated HEVC encoding to shrink large .mov or .mp4 files dramatically without obvious degradation.

Can I use HEVC hardware encoding to shrink video files on Apple Silicon?▼

Yes, you can use HEVC hardware encoding to shrink video files on Apple Silicon by leveraging the dedicated Media Engine. This approach compresses screen recordings quietly and efficiently without stressing your CPU or causing obvious visual degradation.

What is the best way to reduce .mov screen capture file size for long-term storage?▼

The best way to reduce .mov screen capture file size for long-term storage is applying a near-archive quality preset. This uses HEVC encoding on Apple Silicon to compress screencasts while preserving high visual fidelity for archival scenarios.

Does this video compression method support machine-readable output for automation?▼

Yes, this video compression method supports machine-readable output for automation by providing a --json flag. This outputs structured compression and inspection results, alongside probe and doctor commands to preflight file details and validate your environment.

Why does screen video compression cause high CPU usage on my M-series Mac?▼

Screen video compression causes high CPU usage when not utilizing the Apple Silicon Media Engine hardware encoder. By switching to hardware-accelerated HEVC encoding, your Mac compresses screen recordings quietly and efficiently without stressing the CPU.

Are there limitations when compressing screen recordings on macOS?▼

Limitations when compressing screen recordings on macOS include requiring an Apple Silicon Mac with hardware HEVC support. The process is specifically tailored for screen-content videos like .mov and .mp4 screencasts, and may not suit general video editing workflows.
