Reading Time: 5 minutes

Don’t have native 4K content? You can upscale your existing HD videos to 4K quality within minutes with just software. Here’s how.

Do you want to transform videos to 4K and watch them on a 4K TV or upload them to YouTube or Vimeo?

There are many 4K display options like 4K TVs, 4K monitors, 4K video hosting websites, and so on. But, 4K content production is yet to match the pace. For 4K TV, you’ll need costly subscriptions to watch a few 4K TV shows or movies.

Instead of waiting and paying a hefty price for 4K, you can convert your own video content to 4K effortlessly. This article will introduce multiple software applications that can upscale videos to 4K within minutes.

1. Upscale Videos in VideoProc Converter

VideoProc Converter is a trending software that lets you upscale an HD or 1080p video to 4K. The app utilizes the onboard GPU for faster processing. Its motion-adaptive pixel scaling algorithm is an AI program that can assess sample 4K images to create and place new interpolated pixels.
