It is designed to be a successor to VP9 and offers improved compression efficiency. AV1 is royalty-free and optimized for internet video streaming.","The AV1 format was developed by the Alliance for Open Media, which includes major tech companies like Google, Mozilla, and Netflix. It was created to provide a high-efficiency, open-source alternative to proprietary codecs like H.264 and H.265. AV1 offers superior compression, which reduces the file size of video content without sacrificing quality, making it ideal for streaming services.\n\nThe codec is particularly popular for online video platforms aiming to reduce bandwidth usage while maintaining high video quality. AV1 is supported by major browsers like Chrome and Firefox, and it is increasingly being adopted by video streaming services.\n\nDespite its advantages, AV1 requires more processing power for encoding and decoding than older codecs. However, as hardware support improves, AV1 is expected to become more widespread.",[23,26,29],{"title":24,"url":25},"AV1 Codec Overview","https://aomedia.org/av1/",{"title":27,"url":28},"Wikipedia:
