4K UHD Video Converter - How to Convert Videos to 4K Ultra HD

4K Ultra High-Definition video is a big step in TV technology. With a much higher resolution than the commonly known and used 1080p HD, 4K UHD resolution has already become the trend of Ultra HD TV and digital cinema and will definitely define the future of television. Thanks to the development of 4K, we can now experience better picture quality of the videos in UHD TVs. However, although 4K is finally a mature and accessible technology, we can't deny the fact that 4K movies and TV shows still remains relatively limited to get.

Part 1. What is 4K (Ultra HD)

4K, as the name suggests, refers to a display device or content having horizontal resolution on the order of 4,000 pixels and vertical resolution on the order of 2000 pixels. At its most basic, 4K describes the resolution of your TV set (or the amount of pixels used to make up an image). To put that in perspective, a full HD 1080p image is only a 1920x1080 resolution. 4K screens have about 8 million pixels, which is around four times what 1080p set can display and over 23 times the resolution of SD television. Nowadays, several 4K resolutions exist in the fields of digital television and digital cinematography. For televisions, 4K has standardized to 3840x2160 while digital cinema 4K (the resolution in 4K movie theaters) is slightly higher at 4096x2160.

For most people, these two terms are interchangeable. The simplest way of defining the difference between 4K and Ultra HD is this: 4K is a professional production and cinema standard, while UHD is a consumer display and broadcast standard.

4K TVs have hit the market for a few years and you can purchase some well-performing 4K televisions, such as Vizio's Du series, Insignia's NS-DR710NA17 series, LG's OLED65G6P, Sony XBR-65X950B, Samsung UN65HU8550, etc.

The access to 4K content is limited thought. Currently you are stuck with 4K streams from Netflix, Amazon and YouTube only. Or you can buy 4K movies on physical Ultra HD Blu-ray discs.

If you want to experience the UHD 4K while have no access to a 4K movie or TV show, you can convert your available videos to 4K UHD with Joyoshare 4K Video Converter as we introduced in the following article.
