AV Quality Analysis

Synopsis

Serves an Uncompressed A/V Stream (RGB or YUV) to Your Encoder, Captures the Output of Your Decoder (or Receives a File), Aligns the Streams, and Scores the Quality. We use the Human Visual System to Score Your Quality, Measure the Absolute Difference between what we sent and what we received, and show you the Two Sequences in many Different Views.
