Metrics Don’t Watch Video. People Do.
Current Testing Methods have a Blind Spot
Traditional subjective testing is complex and expensive. Objective metrics like PSNR and VMAF offer fast and cheap workflows, but they measure mathematical distortion, not human perception, and often overlook perceptual quality loss.
Traditional lab-based subjective testing costs thousands of dollars and takes weeks, requiring calibrated monitors, controlled room conditions, and specialized facilities.
Decision-Ready Results in Days
VISTA enables automated, scalable subjective quality testing that delivers structured results in days - so your team can deploy video changes with confidence.
VISTA delivers dozens of independent, validated opinions from real-world viewers, with statistical confidence you can defend.
Viewer Verification Built In
VISTA is built for real-world conditions, not labs. Viewer verification pairs filter out inattentive participants automatically - every session, continuously.
Tests can include statistical validation pairs - identical clips shown on both sides - to establish the confidence baseline for the results
Built from the inside out
Beamr created the patented VISTA to validate CABR, Content-Adaptive Bitrate compression technology which reduces video file size by up to 50% while preserving quality
CABR was validated over 80 test sessions, 976 validated pair viewings, confirming perceptual equivalence to source with statistical confidence exceeding 95%.
