External Resources¶

This page contains external resources, including a list of 3rd-party tools that are built on top of VMAF. You can also find links to webpages where you can download FFmpeg binaries that support libvmaf.

Installation Guides¶

• VMAF in FFmpeg – Installation and Usage Guide for Ubuntu -- VMAF installation guide on Ubuntu
• This fork also ships scripted installers under scripts/setup/ and a per-platform guide in install/.

GUI Visualization Tools¶

• VideoBench -- VMAF, PSNR and bitrate analyzer
• FFMetrics -- Windows-centric GUI for PSNR, SSIM and VMAF visualization
• NotEnoughQuality -- A small GUI handler for VMAF

FFmpeg-based Tools¶

• ffmpeg-quality-metrics -- command-line tool to calculate PSNR, SSIM and VMAF with FFmpeg
• EasyVMAF -- command-line tool with video preprocessing for VMAF inputs
• Video Quality Metrics -- command-line tool which encodes a video using specified x264/x265/AV1 CRF values (or x264/x265 presets) and creates a summary table showing the PSNR/SSIM/VMAF of each encode. In addition, graphs (saved as PNG files) are created where PSNR/SSIM/VMAF score is plotted against frame number.

FFmpeg binaries that support libvmaf¶

If you do not wish to compile FFmpeg yourself, you can download an FFmpeg binary that supports libvmaf.

• Windows: gyan.dev builds. Download one of the git builds. The "git-essentials" build will suffice.
• macOS: evermeet.cx. You should download the snapshot build rather than the release build as the latter (at the time of writing) uses v1.5.2 of vmaf.
• Linux (kernel 3.2.0+): johnvansickle.com static builds. Download the git build. Installation instructions, as well as how to add FFmpeg and FFprobe to your PATH, can be found in the johnvansickle FAQ.
