That's Apple marketing at work... like using the adjective "magical" not long ago. I tried to use one to cast a ton of big and small spells, but never one success... not even a need to call Dr. Bombay.
...like how Apple 8GB or RAM is equivalent to 16GB of PC RAM.
Etc. In case you are wondering, some Samsung phones have had 8K video capture since 2020... soon to be FIVE years ago. Rumors have been flying since- including
a very prominent one in 2022- about Apple going there too... but nothing. Conceptually, with all cameras going 48Mp in the next generation, there would seem to be little to hold Apple back hardware-wise... but I wouldn't hold my breath.
If you want/need 8K video capture, look elsewhere. Apple will go there eventually but eventually can be any number of years. In the meantime, bring the topic up around here and- just like it was when there was desire for 4K while Apple clung to 1080... and 1080 while Apple clung to 720p- "we" can't see any point, "until everything in the iTunes Store is 8K", "nobody can see", the chart- the chart, "there's no 8K content so no point in it, etc (all the VERY SAME arguments made against previous resolution tiers right up until Apple made the hop... and then all that just evaporates as if no one ever felt that way).
Being able to capture in 8K doesn't force everyone to capture in 8K just as being able to capture in Spatial doesn't force everyone to capture in Spatial. 8K options in the iTunes Store doesn't eliminate all of the existing options for those with slower Internet or just perfectly happy with the "as is." No the whole internet doesn't have to be upgraded first... just as it didn't for 4K or for 1080p before that.
Capturing some video in 8K doesn't force throwing out any one 4K or 1080p TV already in someone's home because higher resolution video will easily and beautifully scale down to lower resolution displays. Many of the newer Macs can work with 8K monitors now but almost everyone has them connected to 5K or 4K or less and it all works just fine. Same here: higher hardware capability scaled DOWN just fine.
Shoot in 8K now and when the rest of tech "catches" up, you'll have a solid base of content ready to fully take advantage of it. In the meantime, 8K video will look great on lower resolution screens. That doesn't work the OTHER way though: shoot in lower resolution and you have to "invent" pixels to fill future screens that will certainly be higher resolution than 4K-6K. It is definitely coming- no question at all about it- but no-one gets to come back from the future to recapture a precious moment(s) in 8K when it is commonplace.
Two more "oldie but goodie": yes, there ARE abundant 8K TVs in store with some customers owning ALL of them... so yes, there ARE 8K TVs in homes. Someone(s) will sling how no one owns 8K TVs just ignoring the reality of how no retailers are going to stock all those many models to never sell a single unit. And "99% don't want" is usually based on a survey of ONE person. Anyone already owning an 8K TV probably highly covets a way to get more true 8K content on that TV... and Apple could lead they way there instead of dragging in LAST... as they did with 4K and as they did with 1080p.
All that offered, the playbook appears to be let Roku, Chrome, Amazon, Samsung, etc all go to the next tier FIRST, so I don't expect that to change here... in spite of multiple 48Mp cameras being in the next iDevices and all of the abundant spin in Apple marketing all the way back to M1 about how readily it works with "multiple streams of 8K video."
