  • Short answer yes. Much longer. More complex answer. Mostly. If you’re planning on your devices being able to support hardware decoding and large resolutions/ high frame rates. Sit-top boxes and appliances are not quite there right now. I believe the newer Chromecast HD absolutely supports av1. But most of the older Chromecast including Chromecast TV do not support it directly. So it will have to be re-encoded to be streamed.

    That said, the codec itself is fantastic. As an example for animated content, especially. I have some super high quality rips of the old old cartoon from the '80s of the Ghostbusters franchise. We’re talking nearly a gigabyte encoded in h264 for a 22 minute episode. At SD resolution. Upscaling them to 720p and encoding them with av1. And a constant rate factor of about 40. They’ve been coming in between 80 and 200 MB in episode depending upon how much movement there is etc. The one thing with av1 is That as it degrades it sort of smooths everything which works out perfectly for animation most of the time. It can work for live action etc. As well. But you will encounter smoothing as detail is lost. But overall, it is much more preferable to the H style codex so far
