Netflix has successfully integrated the AV1 codec into its streaming infrastructure, where it now accounts for 30% of all viewing traffic and is on track to become the platform's primary format. This transition from legacy standards like H.264/AVC is driven by AV1's superior compression efficiency, which allows for higher visual quality at significantly lower bitrates. By leveraging this open-source technology, Netflix has enhanced the user experience across a diverse range of devices while simultaneously optimizing global network bandwidth. ### Evolution of AV1 Adoption The journey to 30% adoption began with a strategic rollout across different device ecosystems, balancing software flexibility with hardware requirements. * **Mobile Origins:** The rollout started in 2020 on Android using the "dav1d" software decoder, which was specifically optimized for ARM chipsets to provide better quality for data-conscious mobile users. * **Large Screen Integration:** In 2021, Netflix expanded AV1 to Smart TVs and streaming sticks, working closely with SoC vendors to certify hardware decoders capable of handling 4K and high frame rate (HFR) content. * **Ecosystem Expansion:** Support was extended to web browsers in 2022 and eventually to the Apple ecosystem in 2023 following the introduction of hardware AV1 support in M3 and A17 Pro chips. ### Quantifiable Performance Gains The shift to AV1 has resulted in measurable improvements in video fidelity and streaming stability compared to previous standards. * **Visual Quality:** On average, AV1 streaming sessions achieve VMAF scores that are 4.3 points higher than AVC and 0.9 points higher than HEVC. * **Bandwidth Efficiency:** AV1 sessions require approximately one-third less bandwidth than both AVC and HEVC to maintain the same level of quality. * **Reliability:** The increased efficiency has led to a 45% reduction in buffering interruptions, making high-quality 4K streaming more accessible in regions with limited network infrastructure. ### Live Streaming and Spatial Video Beyond standard video-on-demand, Netflix is utilizing AV1 to power its latest innovations in live broadcasting and immersive media. * **Live Events:** For major live events, such as the Jake Paul vs. Mike Tyson fight, Netflix utilized 10-bit AV1 to provide better resilience against packet loss and lower latency compared to traditional codecs. * **Immersive Content:** AV1 serves as the backbone for spatial video on devices like the Apple Vision Pro, delivering high-bitrate HDR content necessary for a convincing "cinema-grade" experience. As AV1 continues to displace older codecs, the industry is already looking toward the next milestone with the upcoming release of AV2. For developers and hardware manufacturers, the rapid success of AV1 underscores the importance of supporting open-source media standards to meet the increasing consumer demand for high-fidelity, low-latency streaming.
