Upscaling 4K

4K upscaling is a process that converts a lower-resolution video, such as standard definition (SD) or high definition (HD), into a 4K-resolution video. The goal of 4K upscaling is to provide a higher-quality image by using 4K resolution, which is 3840 x 2160 pixels. This can be particularly useful when you are watching videos on a 4K TV or screen, as it can significantly improve image quality.

4K upscaling is achieved through the use of image processing software and image reconstruction techniques, which make it possible to add pixels to the original image in order to improve it.
