About:
ab-av1 is a command-line tool that automates the process of re-encoding videos to the AV1 codec. It leverages ffmpeg for video processing, SVT-AV1 for high-efficiency encoding, and VMAF for perceptual quality scoring. The tool intelligently targets a specific quality level or file size, automatically finding the optimal encoder parameters to minimize file size while maintaining visual fidelity.
Key Features:
  • Automated quality targeting using VMAF metrics
  • Support for SVT-AV1, x265, and x264 encoders
  • Automatic CRF (Constant Rate Factor) searching for optimal file size
  • Hardware acceleration support via ffmpeg
  • Batch processing capabilities
Use Cases:
  • Archiving personal video collections with maximum efficiency
  • Reducing bandwidth usage for media servers like Plex or Jellyfin
  • Automating video transcoding pipelines for content creators
Alternatives:
  • HandBrake – HandBrake offers a GUI and is more user-friendly, but ab-av1 provides superior automation and AV1-specific optimization for CLI workflows.
  • FFmpeg – FFmpeg is the underlying engine, but ab-av1 adds a higher-level workflow for quality-based targeting and VMAF analysis.
