recommendPart 1: What Is 4K Video Converter

A 4K video is the standard of video resolution that has the width of 3840 pixels and the height of 2160 pixels. This video resolution is four times the width and twice the height of 1080p Full HD video. You can also say it is Ultra HD resolution where the pixel density is 8 times the pixel density of full HD. Since they are high-resolution videos, they take up a lot of space. They are also very difficult to edit or share as they are in a larger file format. A 4K video converter is a simple software that will take a lower resolution video, like a 1080p file, and “upgrade” it to a 4K video. This saves you the trouble of having to re-edit the video in a software like AVCLabs Video Enhancer AI.
