YouTube AV2 Rollout Could Bring Better Video With Less Data
YouTube is preparing to introduce AV2 streaming on its web platform as early as 2027, potentially bringing better picture quality and lower bandwidth requirements to viewers. The move would mark an early step toward wider adoption of the next-generation video codec.
The Alliance for Open Media released AV2’s definitive specifications earlier this year. The successor to AV1 promises efficiency improvements of approximately 25% to 32%, allowing services to deliver comparable video quality using less data—or improve image quality without increasing the bitrate.
YouTube targets an early-2027 web rollout
According to FlatpanelsHD, YouTube plans to begin offering AV2 streams on the web as soon as early 2027. That gives the platform a tentative rollout window, while other major streaming companies have yet to outline similarly specific plans.
YouTube Engineering Director Des Keane said the company’s support for open codecs is driven by its aim to improve video quality while minimizing playback interruptions. He also highlighted how extensively YouTube already uses AV1: as of March 19, 2026, more than 90% of its catalog, weighted by watch time, was available in the format.
Keane said AV2 would build on that foundation, delivering better picture quality and enabling new multi-video capabilities. The initial rollout is intended for YouTube’s web experience; the announcement does not establish a timeline for availability across its other apps and platforms.
Benefits could extend beyond conventional streaming
AV2’s potential is not limited to making individual videos more efficient to stream. Chrome Engineering Vice President Jim Bankoski said the format could also support improvements to multi-view experiences and video conferencing.
Bankoski pointed to interest from YouTube, Netflix, and Prime Video as evidence of growing support for the technology. Alongside higher-quality streaming, he identified more efficient, higher-resolution video calls and improved multi-view playback as areas that could benefit.
Those comments suggest AV2 could eventually influence a broader range of browser-based video experiences. However, interest in the format should not be confused with a confirmed launch schedule for every service exploring it.
Device support remains a hurdle
YouTube’s proposed launch window does not mean AV2 will immediately become widely available. Adoption will depend on compatible software and hardware, and support remains limited at this early stage.
AV1’s history illustrates how gradually that ecosystem can develop. The codec launched in 2018, but smartphone support arrived in stages. Hardware decoding, which enables playback, appeared well before the Pixel 10 introduced AV1 encoding for recording videos in the format. Those are separate capabilities, so the timing of recording support does not indicate when AV1 streaming became possible on phones.
For AV2, YouTube’s planned web rollout represents a starting point rather than an industry-wide transition. Its promised efficiency gains are substantial, but broader availability will depend on how quickly browsers, streaming services, and device manufacturers implement support.
