Well, I'm interested in AV1 as a videographer but hadn't heard of it before. Without 'codec' in the title I would have thought it was networking related.

Re: HDR - not the same thing. HDR has been around for decades and every TV in every electronics store blasts you with HDR10 demos. It's well known. AV1 is extremely niche and deserves 2 words to describe it.

AV1 has been around for a decade (well, it was released 7 years ago but the Alliance for Open Media was formed a decade ago).

It's fine that you haven't heard of it before (you're one of today's lucky 10,000!) but it really isn't that niche. YouTube and Netflix (from TFA) also started switching to AV1 several years ago, so I would expect it to have similar name recognition to VP9 or WebM at this point. My only interaction with video codecs is having to futz around with ffmpeg to get stuff to play on my TV, and I heard about AV1 a year or two before it was published.

I'm old (50) and have heard AV1 before. My modern TV didn't say HDR or HDR10 (it did say 4k). Agree that AV1 should include "codec".

One word, or acronym, just isn't enough to describe anything on this modern world.
