https://wccftech.com/intels-av1-encoder ... vidia-amd/Intel is the first GPU manufacturer to offer AV1 encoding capabilities within its Arc graphics lineup. Thanks to YouTuber EposVox, who tested the technology on an Arc A380 graphics card, we were lucky to see the encoding in action. The YouTuber discovered that AV1 is highly efficient for video streams that produce a low bit rate. It outperformed all H.264 hardware encoders, such as the NVENC encoder from rival NVIDIA.
Intel AV1 Encoder outperforms rival NVIDIA's NVENC H.264 video codec
Many videos on YouTube that are watched daily have adopted the new AV1 encoding, especially over the last few years of development. Intel's AV1 video encoding was initially developed by the Alliance for Open Media as a royalty-free open-source video coding format in 2015. The format is revolutionary in theory and free, allowing it to be more accessible for users to utilize via the Internet. AV1 produces fewer file sizes than the H.264 format, offering a vastly larger compression capability.

Royalty-free and 30% better. Where do I sign-up? But there is a problem, actually a huge problem. Encoding AV1 files is slow. My original 4K clip from my smartphone is 15 seconds long. To encode it, using software only, into H.264, on my PC takes around 1 minute, so four times longer than the clip length. If I use hardware acceleration available in my NVIDIA video card, then it takes 20 seconds. Just a little longer than the original clip.
For H.265 things are a little slower. Software only encoding takes about 5 minutes, quite a bit longer than the original. Fortunately encoding via hardware into H.265 also takes just 20 seconds. So hardware-enabled encoding of H.264 and H.265 are similar on my setup.
Before all the video geeks start screaming, yes, I know there are a billion different settings that can alter encoding times. I did my best to make sure I was encoding like-for-like.
My hardware doesn’t support AV1 encoding, so my only option is software-based. The same 15-second clip, that took five minutes for H.265 in software, takes 10 minutes for Av1. But that wasn’t like-for-like, that was tweaked to get the best performance. I tested several different variations of the quality settings and presets, 10 minutes was the best time. One variation I ran took 44 minutes. 44 minutes for 15 seconds of video. This is using the SVT-AV1 encoder that Netflix is keen about. There are alternatives out there, but they are much slower, like hours and hours, much slower.
This means that if I have a one-hour movie I have edited from my vacation way to somewhere exotic, then to convert it to H.265 using hardware acceleration on my PC will take 80 minutes. The same file using the current software AV1 encoders will take 40 hours!
That is why it isn’t ready for the masses (yet). Improvements will come to the encoders. The software will get better and hardware support will start to appear. The decoders are already becoming lean and efficient, that is how Netflix is able to start streaming some content in AV1 to Android devices. But in terms of a ubiquitous replacement for H.264? No, not yet.
and why they had to come up with AV1, due to royalties
