== 编码规范 ==
AV1拥有三种設定（Profile）供解码器使用'''Main'''、'''High'''与'''Professional'''。Main允许8、10位元的色彩深度以及4:0:0（灰阶）和4:2:0的[[色度抽样|色度抽样]]。High后续会支持4:4:4的色度抽样。Professional将会完整支持4:0:0、4:2:0、4:2:2、4:4:4的色度抽样以及8、10、12位元的色彩深度<ref>{{cite web|last1=Shilov|first1=Anton|title=Alliance for Open Media Releases Royalty-Free AV1 1.0 Codec Spec|url=https://anandtech.com/show/12601|website=AnandTech|date=2018-03-30|accessdate=2 April 2018|archive-url=https://web.archive.org/web/20190226022722/https://www.anandtech.com/show/12601/alliance-for-open-media-releases-royaltyfree-av1-10-codec-spec|archive-date=2019-02-26|dead-url=no}}</ref>。
