So I'm having a similar problem, CPU usage is high when rendering in Blender and GPU usage is low. I'm using one of the Arc cards you mentioned which I specifically bought for AV1 and the files don't even open. Not sure if it's a Blender or Intel Issue.
Interesting problem. Though it might have been better to make clear from the start, or even in the title, that it will not affect a modern 40 series card.
Here's the issue with AV1 encoding. It's so efficient with compression, but higher compression rates means that packing it up and unpacking it is gonna be slower and more impacting to your performance. And that is literally the reason why hardware AV1 encoders capable of encoding live are only available on the latest bleeding edge GPUs (like NVIDIA GeForce RTX 40xx series). Cuz older GPUs are not powerful enough to encode your livestream 60fps with AV1. You can encode your RUclips video with it, but if the video is an hour long, it will take at east 90 minutes to finish encoding, depending on your options. If you encode with your CPU, your encoding time more than triples the video length. Efficient compression means longer and more complicated encoding process. Easy as that.
yup, thought I'd give it a go on the CPU, and almost there. For the Moment AV1 will remain for my storage. When I get new hardware in the future I'll re visit it :)

Opening video files- I always have used VLC- www.videolan.org
If it cannot open your video file, it probably isn't a video file :)

Thanks for the feedback
