Even a still photo on a flat panel display is still going to be 120Hz or 240Hz or what every native frame rate the display uses. Flat panels never use less then 60Hz in the USA or 50Hz in Europe since any lower there would be a unwatchable flicker on the screen when going below 60fps or 50fps.

On flat panels resolution is the full 4K on a still photo, its when motion occurs is when the resolution on all flat panels drops below 3840 x 2160P. High-end DLP projectors do not have that limitation.

4K UHD Blu-ray can do 24 FPS and 60 FPS (along with 23.97, 25, 50 and 59.94). It can't do 48 FPS.

48fps would need to be converted to 24fps or 60fps by the 4K Blu-ray player or before the disc is mastered. 48fps would require a firmware update most likely on 4K Blu-ray players to officially add that frame rate to the specs. Hopefully future high frame rate movies well be shot at a native 60fps since that would be ideal for 4K Blu-ray, 4K streaming, and a massive amount of existing 4K displays and 1080P displays on the market.

If a 8K optical disc format were to launch around the year 2026, hopefully that optical disc format well support 120fps at 8K. In the ideal world an optical disc format should support frame rates between 24fps to 120fps+. The human eye when looking at the sky on a sunny day sees things at zero frames per second. While DLP projectors can get down to zero frames per second, the overall image quality is better at 24fps and higher.

Moves can look real nice at 60fps and higher if the film crew decides to use that level of high quality frame rate.

Some people well stick with 24fps for movies because they like the look of 24fps or 72fps when 24fps is triple flashed on the screen. I do hope that one day we get some native 60fps movies released on the 4K Blu-ray format. Almost 100% of old consumer 720P, 1080P, and 4K displays can handle 60Hz over HDMI and natively well display 60Hz (60fps) on the screen or multiplies of 60Hz for LCD and OLED flat panels like 120Hz or 240Hz.

You’re mixing frame rate and refresh rate. They are not the same.

Folks will start complaining about a lack of film grain.

Today Sony announced the Venice 2 cinema camera with a new full frame 8.6k sensor. It can do 8.6k 1.5:1 up to 30fps or 8.2k 1.89:1 up to 60fps.

And a couple months ago, Red announced the V-Raptor which upgraded their VistaVision-sized 8k sensor to capture up to 150fps in 2.4:1 or 120 fps in 1.89:1.

Just mentioning it because I assume more movies will start shooting in 8k, even though mastering in 4k is only now starting to become more prevalent.

ARRI is always behind the pack, but I'm sure they're working on an 8k sensor too. Supposedly, their next product is upgrading the smallest Super35-sized sensor to 4k. So I can imagine them upgrading the 65 or LF sensors to 8k based on the new design would follow.

How about having Geoff Burdick, the VP of Production Services at Lightstorm (Cameron’s production company), telling you what they’re doing?

Chapeau to Penton for posting that link a few months back.

This is the exact same process as what is done with any TV showing 24fps content. If you have a 96 Hz display for example, each frame is shown 4 times to keep the correct framerate and reduce flicker on that display. Heck, even a film projector has a rolling shutter that displays each frame twice to accomplish the same thing (and block out the movement between frames).

Is there any streamer at the moment that can stream out (via HDMI) 8K YouTube videos?

[Robert Zohn]

I have the ^ same question. So I can see Native 8K Youtube videos on our Sony Z9J.

A PC.

What happens when you load the YouTube app then search for an 8K video? Will they play in 8K?

From what I've read the Sony TVs can't play Youtube 8K because they don't support AV1. And they can't play 8K from the internal media player either. Only option is external device.

I'm not 100% sure, but I don't think there are any at the moment. I know the two gaming consoles have HDMI 2.1. But I don't think their app supports AV1 8k. The latest Apple TV 4K also has HDMI 2.1. But Apple doesn't support AV1 in any of their products, at all. The latest Amazon Fire Stick Max touts AV1 support. But their specs don't mention if they are using HDMI 2.1. And only support 4k so far. So it might be possible one of these gets a surprise update next year. But it's more likely we'll just have to wait for a new device. Maybe something will pop up in 2022. Isn't the Nvidia Shield due for some new hardware?

Were there any problems with streaming 4K for early 4K TVs too?

Now that's big news with some very nice new features, like displaying up to 4 sources on the TV at the same time.

In 5 years 8K streaming and maybe 8K optical discs will become the norm. Until then people should enjoy their current 4K Blu-ray discs and 4K streams. Nothing beats the picture and sound quality of 4K Blu-ray in the year 2021.

Not a snowballs chance in Hell of that happening. 8K will be regulated to a production format, not a consumer format for the most part. Yes a few TV OEMS will try to bilk 8K TV owners into some 8K content streaming service you pay for per month but they will go nowhere with their nature/documentary content.

If you had said 10 years, I might have agreed with you somewhat. But 5 years? Not a chance.
