Revisiting Bjontegaard delta bitrate (BD-BR) computation for codec compression efficiency comparison
Nabajeet Barman, Maria G. Martini, Yuriy A. Reznik · 2022
Bjontegaard Delta Bitrate (BD-BR), proposed in 2001, remains one of the most widely and also misunderstood tools for the computation and comparison of codec compression efficiency of two or more video codecs. This paper presents three different studies evaluating different open-source implementations, extensions and alternatives on two different datasets, considering three objective quality metrics (PSNR, SSIM and VMAF) and subjective quality ratings.
