H.265, standardized as HEVC in 2013 by the same ITU-T\/ISO-IEC collaboration model that produced H.264 (this time named the Joint Collaborative Team on Video Coding), roughly halves the bitrate needed for equivalent visual quality. That efficiency gain made it the natural successor for 4K and HDR content, and Apple adopted it as the default capture and encode codec across iPhone, iPad, and Mac starting with iOS 11 and macOS High Sierra in 2017, backed by dedicated hardware decode\/encode blocks in Apple Silicon.<\/p>
HEVC’s defining complication, though, is licensing fragmentation. Where H.264 settled into one dominant patent pool, HEVC essential patents are split across as many as three separate pools \u2014 MPEG LA, Access Advance, and Velos Media \u2014 meaning an implementer can, in principle, need to clear licenses with multiple administrators just to ship a compliant encoder or decoder. This fragmentation is widely cited as the direct catalyst for the creation of the royalty-free AV1 codec by the Alliance for Open Media. In 2025, Access Advance absorbed Via LA’s HEVC and VVC pools, consolidating roughly 80% of essential HEVC patents under one administrator, and set a new rate structure effective 2026 that runs through 2030 \u2014 a genuine, current licensing shift worth tracking rather than citing older figures as still accurate.<\/p>
The licensing complexity has had a direct, visible effect on browser support: Chrome and Firefox both declined to ship default HEVC playback for years specifically because of the royalty cost, something H.264 and AV1 never faced. That only began to change in the 2024\u20132026 window, and even now HEVC support in Chrome and Firefox is often conditional on platform and available hardware decode rather than universal. For a DAM handling HEVC-native camera footage \u2014 which is most iPhone and many professional camera exports by default \u2014 that gap means an H.264 or AV1 delivery proxy is still often necessary for guaranteed browser playback, even though HEVC itself is the more storage-efficient archival choice.<\/p>","protected":false},"excerpt":{"rendered":"
