About the project

VMAF is Netflix's Emmy-winning perceptual video quality assessment algorithm, shipped as a C library plus Python tooling. It scores how close an encoded video looks to its source and supports model training.

Useful for
  • Score encoded video against its source to compare codec or bitrate settings
  • Run VMAF as an FFmpeg filter (--enable-libvmaf) in an encoding pipeline
  • Train and validate a custom VMAF model on your own dataset with the Python library

3.2 Breakout Magnitude out of 10 — how fast interest is growing, not a quality score.

Star growth looks organic. Data as of October 19, 2026, 05:05 UTC.

The star-growth assessment does not verify whether the project is safe to run.

Stars per day

01225July 22, 2026October 19, 2026

Bars show stars per UTC day; the line is a moving average of available history. Gaps mean missing data, not zero growth. Today's bar is incomplete. Red marks spike days.

Why it’s trending

  • Star-counter measurements on 2026-10-19 (UTC), 03:33–04:57: 5556 → 5556 stars (+0). This is the change over that interval.
  • Estimated end-of-day forecast: about +14 stars, using observed gains and the previous day.
  • Before this, the repository barely got any stars — about 2 per day.
  • Hacker News: “Netflix vmaf: Perceptual video quality assessment based on multi-method fusion” — 21 points, 8 h ago.

Measured growth: the last 7 completed days

New stars over 7 days: 33. +200% versus the preceding 7 days.

Star trust

Growth looks organic: forks and discussion are in line with active projects, and stars arrive unevenly, the way people give them.

These are heuristics, not a verdict: we judge by the repository’s behavior, not by a list of stargazers.
