VMAF is Netflix's Emmy-winning perceptual video quality assessment algorithm, provided as a standalone C library (libvmaf) with a wrapping Python library. It fuses multiple quality metrics into a single score and also includes implementations of PSNR, PSNR-HVS, SSIM, MS-SSIM, CIEDE2000, and the CAMBI banding detector, plus tools for training custom models.
Use cases
- measure perceptual quality of encoded video against a reference
- compare video codecs with a quality metric
- train a custom video quality model for my content
- detect banding artifacts in video with CAMBI
- compute PSNR, SSIM, or MS-SSIM between two videos
- integrate video quality scoring into an encoding pipeline via ffmpeg
When to choose
- you need an industry-standard full-reference video quality metric
- you're evaluating or tuning video encoders and codec settings
- you want to train a quality model tailored to your content distribution
When to avoid
- you need no-reference quality estimation without a source video
- you need audio quality assessment
- you want a simple GUI tool rather than a library/CLI
