More than a decade ago, in 2007, a video clip was taken for a major event in the village, a few days later. I took my flash in my pocket and headed towards an empty house

He was the one who filmed on his phone, so most people could not afford a phone like that because High price, and the characteristics of the phone was "amazing" in his time, especially the accuracy of the camera and the quality of video

It was the Nokia N80

I still remember that section until today, and when I watch it I notice the great difference in quality and accuracy between it and any other clip filmed by any modest phone these days, but I remember then I was impressed by the quality and size of the video, if someone asked me then the quality of the video is satisfactory I did not hesitate Instant Bean: Yes

I wonder now: Will the quality of the video we are filming these days be satisfactory after ten years

There is a problem I have in terms of choosing the best resolution when taking pictures and videos to document the moment and record the memories. I know that these pictures and clips are not for now, for the future, in order to return to them after many years and remember those beautiful moments. The HD of the video is satisfactory at that time, or will I be embarrassed when I see these clips and regret that I did not portray them with better accuracy

On the other hand, high-resolution imaging costs in storage space. The problem is that these images and videos are files that can not be scanned. They stay with you year after year, and each year the load increases more and more (unless you use cloud storage) With you, as you move between computers or hard drives, these storage media are too many to crash, let alone the backup burden, which protects you from the treachery of time and the sudden bumps of the Bad Sectors

Let's focus - in this article - on the videos, because the images can eventually be loaded, the picture will not be more than 5 MB in most cases, and the video is the problem, may imagine a small clip of three or four minutes accuracy of 4k, surprised that Its size has exceeded the Gigabit Ethernet, and one clip after another until you are surprised that the storage space has run out of you.

 what is the 4K

Is the code for the resolution of the video, resolution is the size of the video surface width and height, the more accurate the more details appear in the image, the accuracy is not the space of the screens themselves, the space in general measured in inches and inches, for example there are smart phones the size of screens 5 inches, Accuracy is the amount of pixels that this screen can accommodate. You may find two phones that are equal in size, but the accuracy of the first is greater than the second resolution, so the colors are bright and the details are clearer.

As for the label, the 4K simply symbolizes the total number of pixels each video frame contains, ie the video surface is 4,000 pixels, also referred to as Ultra High Definition or UHD

When the 4K becomes useful

The 4K resolution gives a video advantage by showing it for more details. The difference will be great only when the video is displayed on large TVs, which of course supports this resolution, especially when you are close to the TV. Then you will be able to see the exact details, In the video

When you watch a relatively small television or watch the video on your phone even if it supports this kind of accuracy, you will not notice the difference, and when you watch the big TV but from afar, you will have a 4k resolution with 2k

Although YouTube has opened the way to upload 4k clips for many years, publishing clips with that accuracy is not very important, only adds a great burden to the content maker. Not only is the space the problem, but even dealing with those videos during the editing takes time If the video is uploaded to the Internet, the length of the video will be long and the package will be exhausted, so why should a person upload such clips and only a small percentage of viewers who open YouTube on large TVs will benefit

On the user side, most people often do not convert accuracy to 4K, simply because they want to keep the data packet, and because the difference - as we mentioned earlier - is not noticeable

Recently, an autobiographer posted a video testing the difference between HD and 4K quality, filmed a short clip with three different qualities, and asked viewers whether they could tell the difference and distinguish each quality from the other by watching, and the surprise was that it was hard to differentiate them.
