OK, I’ll say it. As far as I know, this is the first time any study has compared the quality and performance of codecs representing Essential Video Coding (EVC), Versatile Video Coding (VVC), and Low Complexity Enhancement Video Coding (LCEVC), as well as AV1, HEVC, and H.264. It’s not as exhaustive as I would like but the results should help …

I recently had the opportunity to test Roland’s V-02HD MK II video mixer.

The 23-minute presentation covers the following agenda with extensive examples. You’ll find the talk useful if you’re comparing per=title encoding features, particularly cloud-based, but also third-party options you can buy/lease and install and run …

Companies attempting to formulate the ideal encoding ladder for specific videos or classes of content should incorporate both the harmonic mean VMAF score for overall quality and the percentile score to minimize transient quality issues.   I’ve spent much of the last few weeks benchmarking H.264 and HEVC cloud-based per-title encoding capabilities like those available from AWS Elemental, Microsoft Azure, Brightcove, …
