AV1
An open, royalty-free video coding standard developed by the Alliance for Open Media (AOMedia), with Google as a primary contributor. It is widely used in video streaming and as the basis for the AVIF image format.
Core Facts
AVIF is essentially the single-frame output of the AV1 video codec packaged as an image format, enabling hardware acceleration by reusing the AV1 hardware decoding capabilities of video chips.
The AV1 codec was jointly developed by the AOMedia alliance and can save approximately 30% of bandwidth compared to H.265 at equivalent video quality, without involving patent licensing fees.
Timeline (last 90 days)
Even today, with the emergence of new-generation standards such as AV1 and H.265, H.264 remains the video coding solution with the broadest compatibility and the most mature ecosystem.
AVIF is based on AV1 intra-frame compression, and at equal subjective quality its file size can often be compressed to about sixty percent of WebP.
AVIF has high encoding complexity and takes a long time to build, and its CPU usage cannot be ignored when batch-processing large images.
AV1 is led by the Alliance for Open Media (AOMedia), with Google participating, while JPEG XL comes from a competing camp.
AVIF is based on AV1 video encoding, and Google is the primary driver of the AV1 ecosystem.

Microsoft is one of the co-developers of the AV1 standard, participating through the Alliance for Open Media.
AV1 was finalized by the Alliance for Open Media in 2018, offers approximately 30% better compression than H.264, is completely royalty-free, and has been adopted by Netflix and YouTube.
