The Honeymoon X265 Jun 2026

H.265 brought advanced motion compensation. It uses merge mode and Advanced Motion Vector Prediction (AMVP) to reduce the bits required to encode motion data. Instead of sending full motion vector differences for every block, the encoder can signal to the decoder to "merge" with motion vectors from neighboring blocks.

The rates were significantly higher than H.264. For tech giants like Google (YouTube), Mozilla (Firefox), and Apple, this was a nightmare. It wasn't just the cost; it was the uncertainty. You couldn't be sure you had licensed all necessary patents. the honeymoon x265
