Part 4. FAQs about Upscaling 1080p/HD to 4K

What is the simplest and easiest way to convert 4K to 1080p without losing quality?

Downscaling a 4K video to 1080p is a bit risky. Changing the sequence and the scale of the clips can turn out into a lossy quality video. The best way to downscale 4K to lower resolution without losing the quality is using the Maximum Render Quality when exporting a 4K video to a lower resolution. This sequence setting is accessible only for some professional video editing software. Especially on Premiere Pro. It may sound unfamiliar to non-premiere users. But this is how to change from 4K to 1080p in Premiere without losing the quality of the video.
