Unmanic is an self-hosted media library optimization application: its role is to automatically convert and normalize video and audio files from a library so that they all adhere to the same format. Open source (GPL v3), it relies on FFmpeg for transcoding.

Its operation is based on a scheduler that scans the entire library for files that do not match your presets, and on real-time monitoring that checks every new or modified file. Non-compliant videos are then queued for conversion.

Unmanic's great flexibility comes from its plugin system: you can convert your files to a uniform format, manage file moves based on their date, or execute custom commands based on size. A web interface allows you to configure, control, and track progress, all easily deployable via Docker (with VA-API / NVENC hardware acceleration possible).
