Is ultra high definition necessary?
February, 26; 2019. By
At present, the need to increase the standard of definition of films is being debated in some circles, both in theaters, as in home cinema, tablets and mobile phones, into ultra high definition or approximately 4K. But is this really necessary?

For the publisher of this publication, the answer is clear: no. For many reasons. One of them is that we have to take into account that we ourselves have enjoyed VHS that had an initial definition of 240 horizontal lines. The standard definition or SD is marked by the DVD format, which is around 500 horizontal lines, twice the VHS. And high definition, either in its simple mode (720 horizontal lines, which would triple the VHS) or the way known as Full HD (1080 horizontal lines, quadrupling the VHS standard), is more than enough for its projection in a cinema or home cinema, taking into account several factors such as the perception of real amplitude of the screen, that is, the maximum that the human eye can differentiate, plus the needs of the moving image, that is, focus on the plot of the film and not get lost in unnecessary details.

Deepening in the latter, the ultra high definition makes unsolicited details emerge as for example bad acne makeup in the foreground or things like that. In addition, taking into account that today's tablets and mobile phones are the order of the day, in short, ultra high definition becomes unnecessary.

There are some purists who say that a movie should be enjoyed in cinemas and with all the necessary blessings, the stars in harmony, etc., but the reality is that movies today are also consumed in tablets and phones in a frenetic and obsessive way by world population. This increases the possibilities of broadcasting a movie and its message exponentially.

To deepen a little more in the matter, this editor has verified, by means of the distribution of the films of the publisher, that what the public demands is standard definition when it is not going to emit in big screen (that is to say, mobiles and tablets) and HD when the film is going to be shown in home theater or in traditional cinema.

So it is quite clear that we should put a stop to this unnecessary increscendo towards the 4K, 8K, 16K, and ultimately, the infinite K.
