Moscow State University Releases 10th HEVC Video Codec Comparison (compression.ru)
An anonymous reader writes: The Graphics and Media Lab Video Group of Moscow State University has released its tenth video codecs comparison. This latest comparison focuses on HEVC codecs and includes some non-HEVC codecs such as x264 and VP9. The report concludes that Intel's MSS HEVC Software codec leads the pack in the "fast transcoding" use case whereas x265 takes the lead in the "ripping" use case. VP9 compares favorably to the HEVC codecs in the fixed quality and the speed versus quality test cases. See the PDF version of the report for more details. -

VP8 and H.264 Codecs Compared In Detail
An anonymous reader writes "Moscow State University's Graphics and Media lab have released their sixth MPEG-4 AVC/H.264 video codecs comparison. Also of note is a recently added appendix to the report which compares VP8, x264, and Xvid. The reference VP8 encoder holds its own against x264 despite the source material offering x264 a slight advantage. The VP8 developers comment in the report: 'We've been following the MSU tests since they began and respect the group's work. One issue we noticed in the test is that most input sequences were previously compressed using other codecs. These sequences have an inherent bias against VP8 in recompression tests. As pointed out by other developers, H.264 and MPEG-like encoders have slight advantages in reproducing some of their own typical artifacts, which helps their objective measurement numbers but not necessarily visual quality. This is reflected by relatively better results for VP8 on the only uncompressed input sequence, "mobile calendar."'" -
