I don't understand how google can just be consistently on the back foot of the "tech world hivemind" for going on 7 (?) years now and have zero shakeup of not just culture but at least PR.

The company is literally run by a McKinsey consultant. How is anyone surprised?

Indeed. Why do the engineers cope with that?

Google, not content with existing image formats that support 10-bit like HEIC (used by Apple) and AVIF (based off of AV1, a codec that Google helped design and is better than JPEG), they decided in all their wisdom to make Ultra HDR for Android phones, which is an incompatible standard built on top of JPEG, which is separate from JPEG-XL. Now Samsung has released Super HDR, without any information about that standard…

Considering JPEG XL and Ultra HDR are both based on JPEG, couldn't they be combined into one standard? Wouldn't it be better for everyone if the whole industry could eventually agree on a single standard?

Apple's HEIC is very annoying since it's not really supported by anything non-Apple. Would certainly be nice to see that go away.

I worked alongside the Google and Cloudinary teams who authored the JPEG XL spec and I'm glad their work's finally paying off. It's really weird Google deprecated the format despite contributing engineers to help build JPEG XL. I guess it's office politics

They want their awful webp format to win for some reason.

From a technical perspective, what are the differences between the two?

It's crucial to distinguish JPEG the file format (now retronymed as JPEG 1) and JPEG the standardization group.

JPEG XL is officially blessed by JPEG but otherwise irrelvant here, even though non-progressive JPEG 1 files can be losslessly recompssed into JPEG XL by its design. The main role of JPEG here was to specify explicit goals for JPEG XL proposals [1]. Interestingly enough, the JPEG 1 recompression was not a part of that call for proposals back then. JPEG XL is otherwise a completely different format with much better compression algorithms, so should be the image format for pretty much all uses once popularized.

Ultra HDR [2] is an extension to the JPEG 1 format, which depends on XMP and the CIPA Multi-Picture Format. This kind of extension was not the first, even JPEG the group itself had a similar extension called JPEG XT which was never popular! (If you don't know much about JPEG, APNG was a similarly designed extension to PNG which eventually became a part of PNG.) Naturally Ultra HDR files cannot be smaller than ordinary JPEG 1 files, so can't fulfill Samsung's needs.

Because pleasant coworkers, a comfortable physical work environment, and some prestige for a mid-six-figure salary is one hell of a deal for humans

Honest question: what’s so awful about WEBP? Though it’s worse than the gen arriving now, it’s better than or the same as the one before it for the use cases it supports, and free and open. I get the impression people associate it with brokenness and low quality, but the brokenness is just a lack of support, and the quality a creator choice. Maybe its original sin was not trying to be suitable for original data, leading to the low quality association and making support less desirable outside of the web, but if that’s the case then AVIF is in the same boat.

Ultra HDR is a relatively unambitious standard. JPEG XL already supports hdr, but also has a ton of other nice features (extra channels, bigger maximum resolution, high bit depth, better entropy coding).
