The AV1 format allows a lot more options when encoding, so encoder writers kinda feel obligated to try a bunch of them out to see if they save bandwidth. But if instead a codec just picked a few optimizations and ignored the rest, it could be pretty fast. Maybe Google just found a set that worked well for an average video chat.</text><parent_chain><item><author>Polylactic_acid</author><text>Everyone is commenting on the product but what I want to know is how on earth they are able to encode AV1 in real time. I tried AV1 encoding a few months ago and was getting about 0.3fps encoding 1080p video on an i7 4770k. I&amp;#x27;m guessing the default settings on the av1 encoder are more focused on size over speed but still, how could they be getting 30fps video encoded in real time on a phone..</text></item></parent_chain></comment><story><title>Google Duo rolls out realtime AV1</title><url>https://www.blog.google/products/duo/4-new-google-duo-features-help-you-stay-connected/</url></story>

The lossless bitstream compression part of video encoding can be a very significant portion of the encoding time on faster speed settings, so lower bitrate means faster encodes.&lt;p&gt;It also probably isn&amp;#x27;t 30 fps.</text><parent_chain><item><author>Polylactic_acid</author><text>Everyone is commenting on the product but what I want to know is how on earth they are able to encode AV1 in real time.
