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><author>sp332</author><text>The speed of an encoder really comes down to how many optimizations it&amp;#x27;s searching through. 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></comment>

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></comment>
