All of us are quite familiar with 1080 p for quite some time now. However, the introduction of HD has introduced us to a resolution higher than 1080p resolution. 4k UHD is mainly found or used in digital cinemas where the resolution is 3840x2160 pixels. It is also used in UHD television with a resolution of 3840x2160p.

With 4k technology, users get to enjoy a detailed screen of videos and movies, and this thing was not possible before. Now since the concept of 4k is relatively new, there is a limited number of devices present to play it and also there are not many options to play 4k videos in a 4k video player.

However, there are some 4K playback errors. For example, if you record a 4K video using an iPhone, 1 hour ho 4k HVEC consumes about 23.45 GB. Besides taking much space, the videos are unable to play on PCs and game consoles. Incompatible codec and lagging hardware are the reasons for such problems. To handle 4k files in a better way, we require a 4K converter to convert 4k to H.264, 1080/720 pixel to make it well suited with the present hardware options.

What is 4k format?

To state very clearly, 4K resolution is 3840x2160 pixels. Whereas on the other hand, a Full HD image 1080p is 1920x1080p. This means that a 4K screen has 8 million pixels and it is about four times the Full HD image. If you assume your TV like a grid, then a 1080 pixel image will have 1080 rows and 1920 columns. A 4K image on the other hand doubles this number from both sides, thereby giving 4 times more pixels than a Full HD image.
