Part 1. Understanding 4K Resolution - Why do People Convert Video to 4K?

First, we need to figure out what 4K resolution is. 4K resolution is a horizontal display resolution of approximately 4,000 pixels. In general, 4K resolution refers to motion pictures like television videos and cinematography, but these two use different 4K resolutions. Several common broadcast resolutions, from low to high, are VCD, DVD, 720p,1080p, and 4K. So, 4K adopts a more advanced technology in video resolution.

Next, why we’d better convert video to 4K resolution? It is well-known that modern display devices are commonly updated to 4K. Under this premise, if we play a video with a lower resolution by a device with a higher resolution, the screen will appear with a black margin, or the video needs to extend itself to match the size of the device’s screen. Both of the two situations will reduce the experience of viewers. Considering the clarity of our video, upscaling video to 4K is necessary.
