A small, dependency-free (pure standard-library) Python tool that runs the perceptual quality GATE this article describes, on every rendition, with a CI-friendly exit code. It runs two checks: (1) an ABSOLUTE FLOOR — never ship a rendition below a set VMAF on the mean AND on a low percentile (the worst frames), with the floor anchored to the quality target (premium top rung ~VMAF 93 good-enough / ~95 transparent; Rassool 2017, Kah et al. 2021); and (2) a REGRESSION check against a golden referen

Fora Soft Video Engineering Handbook
This Python tool runs a video quality gate on every rendition: an absolute VMAF floor on mean and low percentile, plus a regression check against a golden reference, with a CI-friendly exit code. Our seven-volume handbook goes deeper: Volume 1 on VMAF and quality metrics, Volume 3 on bitrate ladders and QoE, and Volume 6 on AI models. Written by Nikolay Sapunov, CEO at Fora Soft.
