High resolution 8K video actually appears smoother, softer, and more natural - not clinically sharper, than lower resolution images. I saw this for myself when grading 8K footage from the Canon last night.

Marketing would have people believe it’s all about ‘sharpness’, where in fact, when viewed from a distance, people often mistakenly believe lower res material is sharper. hehe

Higher res also means greater color information.

These qualities are all scalable, meaning they are observable whether seen in 4K, 2K or HD. I’ve watched a lot of videos on this phenomenon and observed the same thing.

Many episodes of the Netflix hit Better Call Saul were shot with an 8K camera.

Because 8K has 4X the number of pixels of 4K it allows tremendous flexibility in post: cropping, zooms, pans and stabilization.

Whether anyone actually needs it or not is debatable.

I am not saying that it is not better. The question was - what makes everybody think that pros really need it? Most customers will view their photos and videos on tablets or phones anyway. Most of them would not be able to tell 2K from 4K, forget about 8K that they cannot view or higher quality 4K downscaled from 8K. After all, many pros shoot with 20mp flagship cams and take videos with smaller format cams.

It was a question.

@JACS Did you even view the video that @jonpais posted?

The pro cinema photographers doing the presentation answer your questions thoroughly and convincingly using the science of eye/brain perception and the current technologies in movie making.

If you have not viewed it, your photography/videography paradigm/opinion will continue to be incomplete. You seem to believe that 8k video is only about perceived sharpness.

Here are a couple of screenshots from the video.

Their paradigm. The elements are interrelated, not separate. They are keys to the image acquisition and manipulation. The points they make show that this is independent of how the image is viewed whether a 4k big screen, 1080 monitor, or smartphone.

Perspective and magnification differences vary by resolution.

Resolution affects depth perception, color, luminosity, tonality, and transitions dramatically. It is about more than just perceived sharpness. On the left is a 35mp(8k) image. On the right is a 100mp(11k) image. (The 8k and 11k "equivalents" are from the presenters.)

Again 35mp left; 100mp right. The cinematographers hope that their technology continues to move toward 100mp(11k in video) because that is what science demonstrates that the eye/brain can see and interpret (this claim is by the presenters). Their opinion: who wouldn't want to see movies that matched the eye's capability and provide an almost completely immersive visual experience.

The competition is intense to provide convincing cinema looks for adventure vs horror vs romance vs comedy vs documentary, etc. So, pros need 8k video if they want to compete.

Cameras for 8k have been out since 2011. Pro bodies range between $60-125,000. Looks like Canon thinks there is an enthusiast/semipro market for it in 2020 for less than $4000. Computer processing power?: Ryzen 16 core - liquid cooled, 64gb ram, NVIDIA RTX 2080 Ti, and nvme drive for less than $4000.

Canon history: first consumer full frame 5D in 2005, first consumer video capable full frame 5D II in 2008.
