Figure 1. BD-rate savings from AV1 as published by Facebook. When Facebook compared the AV1 codec to VP9 and two flavors of H264, their researcher precisely stated, “In terms of PSNR, the average BD-rate savings of AV1 relative to x264 main, x264 high and libvpx-vp9 were 51.0%, 47.0% and 29.9%, respectively.” This means that AV1 delivered the same quality as …
