I have a limited understanding on this, but I'm going to take a shot.
It is my understanding that the ideal frame rate is 24 frames per second (more or less) as this is akin to how quickly your brain and eye relay information between one another in a given second. So now a majority of new televisions offer support for 24p in order to get the optimum performance when watching Blu-ray movies and other compatible material.
I just began reading that 8K is being pushed on the cinema industry to replace 4K video recorders to assist with better color definition, clarity, etc. when downscaled to 4K resolutions. So far only a few 8K recording devices exist, and the one's I've read about record at 60 frames per second.
Now based on what I've learned about 24p I would think that new cameras would use some derivative of that vs. the seemingly dated 60p.
What did I miss?
