Video Encoding: A Complete Guide to Video Compression — From Pixels and Color to H.264, HEVC, AV1, Quality Metrics, and AI
This cheat sheet compares G.711, G.722, AMR and EVS on bitrate and bandwidth and flags the transcoding ceiling when you bridge into the phone network. Volume 1 explains the compression principles behind those numbers: how codecs trade bitrate for quality, rate control, transcoding losses between formats and the quality metrics that show what a codec chain does to the signal. Written by Nikolay Sapunov, CEO at Fora Soft.
