AV1 was developed as a state-of-the-art video codec for distribution over the web by the Alliance for Open Media (AOMedia), which consists of representation from several companies including Amazon, Apple, Netflix, Intel, and Nvidia, and others. It’s designed to succeed AVC, VP9, and HEVC as a next generation of natively supported video codes on consumer hardware devices. AV1 supports up to 12-bit color, HDR, and UHD+ frame sizes for distribution of premium content. In addition, AV1 builds into the specification support for web-focused features such built-in security protocols, end-to-end encryption, and film grain synthesis (a method of reducing the bandwidth required to compress and transmit theatrical content while maintaining the texture, look, and feel of the original film).

AOMedia released the formal specification in June 2018; however, the complexity of the encoding techniques used in AV1 required optimizations for several months before it could reach the encoding throughput of other competitive codecs. AV1’s complexity allows for more compressed video streams compared to popular web codecs like AVC and HEVC, so that video can be delivered at the same quality as AVC and HEVC but at lower bitrates.
