I recently watched the documentary Apollo 11 on my HD TV.
That was the moment, when I realized, that higher definition really makes a difference.
The documentary about the first moon landing was filmed on 70mm material.
There is a remarkable optical difference between 70mm and regular 35mm film material.
It really looks more detailed and more life like.
Apollo 11 was shoot on 70mm film
This translates directly to new camera developements, like the Canon R5 with 8K video resolution.
Canon announced the EOS R5 with 8K video
In the first moment this sounded crazy and exagerated to me.
Who needs 8K anyways?
But when you compare the definition of 35mm to 70mm film this makes sense.
I believe there has to be also a new codec, to bring the moving images to the recording card, without overheating the camera.
But like in the case of Apollo 11 a higher resolution will be for archival purposes very useful.
Not very many people use 4K nowadays.
It will take a couple of years until 8K screens will be wide spread.
The Canon R5 with 8K video is still in developement.
