High-Level View of H.265 Compression Steps

H.265 (HEVC) is a video compression standard that delivers roughly the same quality as H.264 at half the file size. What are the basic steps taken by the H.265 codec to compress a sequence of frames? What are some of the reasons that H.265 provides 50% better compression than H.264? This article covers topics such as coding blocks, intraprediction, interprediction, quantization and entropy coding. It is the second installation of the series Deep and shallow dives into topics related to H.265. You can read the first one here.

Color Science From the Purview of H.265

A few months ago I was given the task to integrate a Vulkan video encoder into our renderer, which would compress frames in H.264/H.265. I went in knowing nearly nothing about video compression and came out with some interesting knowledge I will cover in this new series. This article goes over color-related topics such as chroma subsampling, color gamuts, color spaces and some color science math.
