hello today beautiful morning great mood today I want to talk about such an interesting topic
as recording formats, that is, 2K/4K/full hd/ultra hd to clarify the concepts that exist
and exist today because you meet a lot of people who operate with these concepts such
as 4K 2K in fact, people don’t really understand what it is, and so today there are several
formats, we are used to the full hd format, which today are practically common, well,
in 99 percent of cases and the 4K format is developing very rapidly, but there is also
the ultra format hd, that is, if you come to the store and look at the TV it says 4K
ultra hd, so let's figure out what the difference is, look at the diagram on this diagram, the
first small square full hd is indicated, its dimension is 1920 by 1080 and the formats
are 16 by 9, this is what we are accustomed to, that is, the formats of our TVs and the
formats of computer monitors, even telephones often do exactly about 16.9 this is full hd
and how now from this full hd we get the format 2K how does it differ we look at the second
straight line, that is, the height of our rectangle remains the same and the length
increases by one unit and its format becomes 2048 by 1080 and it turns out that we got
the 2K format and its dimension ratio will be more precise 17 by 9 when we watched TV
earlier there and everyone noticed a black stripe at the bottom and a black stripe at
the top, this is format 2 corp now there is no this stripe on TVs because the TV has it
converts the image to full hd and automatically gives a full-fledged picture if the format
of the film goes to 2K there and we will see the right and left sides in cropped, clarified
truncated form and so on we understand what is ultra hd and what is 4K ultra hd dimension
aspect ratio 16 by 9, the screen dimension is 3840 by 2164, we again look at our aspect
ratio, it turned out to be 17 by 9, that is, the screen stretched on our right and left
we get a dimension of 4096 by 2160, that's the difference, that is, the difference in
aspect ratio, for which there is a 4k ultra hd full glasses or 2K format, everything is
very simple, we all go to the cinema and look at the radiator screen on the screen, there
is from our sides 17 on 9 as well as the projector screen also has an aspect ratio of 17 to 9
for this, just 4k and 2K formats are used
if we watch it all on a 4K TV, respectively, we should see a strip or a truncation of the
crane on the TV and I’ll repeat it again on the right
and left, then the aspect ratio for ultra hd and full hd formats is 16 by 9 reformer
2K and 4K aspect ratio 17 by 9 use correct information shoot beautifully shoot in 4K
shoot in 2K try to repair and let your video be even better and even more beautiful and
even larger in size if you liked the information put likes subscribe to the channel thank you
very much and goodbye and another interesting moment that I forgot about to mention, but
I really want to tell for those who like to shoot 4K under water, there is an interesting
moment when we shoot ordinary video cameras in full hd mode, we see that we have a lot
to weigh a lot under water and this suspension hits our screen, we see a lot of small particles,
do not forget about the moment when you start shooting in ultra hd or 4K format that the
suspension will not go anywhere and the amount of this weighted.
The screen will increase at least as much as yours, so shooting in 4k is best done in
water with a good brother if there is no such transparency, be prepared for the fact that
there will be a lot of garbage on the screen thank you very much shoot beautifully goodbye
