AV1 is goddamn magic. (pawb.social)

that's it that's the post.

JK, but seriously though. AV1 is incredible and I NEED support for hardware decoding to accelerate and fast. I just shoved an 18GB Blu-ray movie into 5 gigs with room for improvement. I can get stream worthy 1080p60 video at 6000kbps when I need at least double that if I use x264. Even at a ok encode speed, the 1080 6000kbps video on YouTube looks pretty good all things considered - sure my super high bitrate x264 video looks clearer, but it's also at least double the file size on my disk.

I could probably real-time CPU encode my streams with AV1. I could definitely do it even better with hardware encoding.

AV1 is black magic. It feels wrong.

For hardware encoding, it will depend on your hardware encoder. Even for h264 etc, the hardware encoders have always been a step down from software encoding. This is a quick chart of Intel's AV1 encoder in comparison to other common software and hardware encoders. It's from this video which iirc was very informative on this topic for the Intel GPUs specifically.

I see they put out at least a couple more videos on AV1 in general here and here if you're interested, but I haven't watched them.

Thank you, that was very informative!
