Frequently asked questions
Why doesn't YouTube use HEVC?
YouTube uses AV1 (and VP9 as fallback) for licensing reasons. HEVC requires royalty payments to patent pool organizations. AV1 is royalty-free, developed by the Alliance for Open Media (Google, Apple, Microsoft, Netflix, Amazon, Meta). YouTube transitioned to AV1 to eliminate licensing costs at scale.
Does iPhone support AV1?
iPhone 15 (A17 Pro) added hardware AV1 decoding but not encoding. Earlier iPhones support AV1 playback only in software. For now, iPhones record in HEVC; AV1 playback works in Safari and apps on iPhone 15+.
