How to Upscale Video from 480p to 4K UHD Handily?

Q: "I watch (stream) mostly older TV shows which are in 480p resolution. If I get a 4K TV, will these shows look OK or will they be pixelated when at full screen? I appreciate any help on this issue."

A: Well, in short, it rather depends on your source video, and the 4K screen size definitely matters as well. Just imagine that, to upscale video from 480p to 4K or 2160p, it must fill in so many pixels to fit the screen. So, if the source video is "poor" then it arguably looks worse or pixelated the bigger the screen size. In other words, it doesn’t make sense to upscale "poor" 480p on 4K TV.

On the flip side, if the source 480p video is encoded in high quality like DVD video, while not quite as good as the real 4K video, the quality is still acceptable after the 480p to 4K DVD upscaling. In addition, you have to know that, most modern 4K devices come with a video upscaler capable of upconverting 480p signal to 4K, but it may will make the video look distorted or stretched if the software isn't that good or smart. Next, I'll introduce 4 480p to 4K converter software to you guys for manually completing the perfect video upscaling.
