Best 4K Upscaling Software: How to Upscale Videos from HD to 4K

4K was introduced in digital cinemas, on-demand streaming services like Netflix, Amazon Prime Video, Disney +, and commonly available in the home television. It is divided into two resolutions: 3840 x 2160 which is referred as Ultra High Definition or UHD, and 4096 x 2160 are officially 4K. Compared with 1080p and 720p, 4K is best for big-screen displays and offers gamers, movies, and TV lovers a better viewing experience.

problem 4K vs 1080P

Resolution is the measure of pixels of the image (the number of pixels in each dimension that can be displayed), quoted traditionally as width x height, and the number refers to the pixel height of the image in a 16:9 aspect ratio, so 1080p is a 1920 x 1080, or 2560x1080 resolution, while 4K also is called 2160p, actually 3840 x 2160, or 4096 x 2160 resolution. In technology, 4K is capable of displaying 4 times pixels than 1080p, and it means a huge increase in display quality. The higher the resolution, the sharper image will be.

In our viewing and recording experiences, 4K means greater detail, contrast, and color.

problem Why 4K Is Significant?

With 4K cameras, 4K games consoles, broadcast TV, 4K displays, and smart TVs more and more affordable and popular, 4K becomes the mainstream in our media life. The streaming video services and cable providers are moving to 4K. Netflix, Amazon Prime Video, Disney Plus, HBO, YouTube already offer a wide range of content such as 4K movies and TV series. Likewise, the game consoles are also 4K supported nowadays.

Recently, more and more people enjoy recording or filming videos using 4K cameras, or smartphones with 4K cameras built-in and share the content with other users by uploading 4K videos to YouTube and Vimeo.

problem Why Do We Need 4K Upscaling?

"If you've got a full HD picture coming into the TV and if you didn't upscale it, it would take up just a quarter of the screen. It would be then surrounded by an empty screen. What the upscaling process does it to ensure that the picture fills the 4K resolution of the screen." -- Gavin McCarron

With the 4K resolution going deep in our media life, many recorded videos were filmed in 4K, however, there are still a lot of lower resolution content, like old movies, commercials, home videos, recorded videos, etc. When you want to watch lower-quality HD (1080p or 720p) videos on the displays that support 4K, upscaling is the solution. Upscaling is done by smart TV and some media players, as well as the video enhancement software.
