... Less sharp screenshots show the maximum level
details, and those that seemed sharp are hopelessly spoiled by a sharpe and lost in detail.
This is what producers & managers do in advertising. In YouTube reviews, the picture appears sharp and
detailed, but as soon as you start to watch the originals in full size,
then you involuntarily think: "Excuse me, but where is the quality???"...
Yes, and besides, the bit rate also affects the quality of the picture.
Currently, the B4K flow rate for UHD is only 27,1 Mbit/s (which is extremely low), and it is required to at least double this figure for 4K.
(This is an indicator of the total bitrate. For 2560x1440 it is 15.0 Mbit / s, and for 1920x1080 it is 8.66 Mbit / s).
