H.265/HEVC vs. H.264/AVC: 50% bit rate savings verified
VP9 vs H264 vs H265:- Next-gen codecs provide 50% bitrate improvements over x264, but are 10-20x as slow at the top settings required to accomplish such results.- Normalized for CPU usage, libvpx already has some selling points when compared to x264; x265 is still too slow to be useful in most practical scenarios except in very high-end scenarios.- ffvp9 is an incredibly awesome decoder that outperforms all other decoders.https://blogs.gnome.org/rbultje/2015/09/28/vp9-encodingdecod...
