## Project history and usage

fx-upscale is a small macOS-oriented command-line tool for Metal-powered video upscaling. It accepts a video file path or URL and outputs an upscaled video using explicit width or height options, or a default 2x upscale.

### Project history

The public repository was created in December 2023, and 1.0.0 was released the same day. Releases continued through the 1.2.x series, with GitHub release metadata showing 1.2.6 in December 2025.

The README positions the tool as a CLI companion to Apple's Metal video capabilities and points users who want an app-based version to Unsqueeze.

### Adoption history

The official README documents installation through the author's Homebrew tap, Mint, and manual GitHub releases. Adoption appears focused on macOS users who want a scriptable alternative to GUI video upscaling tools.

### How it is used

Users run `fx-upscale <url>` with optional `--width` or `--height` values. If only one dimension is provided the other is inferred proportionally, and if neither is provided the video is upscaled by 2x.

The README notes a format behavior for output above 4K: some `.mp4` inputs may be converted to `.mov` and h264 or hevc may be re-encoded as ProRes 422 because of macOS playback and codec limits.

### Why package nerds care

fx-upscale is a niche but neat package-manager specimen: a Swift/Metal media utility distributed as a Homebrew formula and Mint package, exposing platform GPU functionality as a tiny CLI.

Its significance is mostly in showing how modern macOS media APIs can be wrapped as Unix-style tooling rather than as a full application.
