If you’d like to see a couple examples where I tried to enhance some old content myself, click here and here, and make sure to change your YouTube quality setting. Of course, the algorithm doesn’t know that. To be clear, these are both enhanced images, but one is arguably wrong: this is an ethereal, dream-like sequence where the background is supposed to be soft and blurred, not sharp and flat. A lower quality “aliased and moire” setting does a more faithful job at the expense of clarity. Topaz’s “high quality” setting gets rid of the intentional blur / bokeh and flattens the image. Here’s two different algorithms trying to enhance the same scene in Gundam Wing, so you can see what I mean. I found 4K videos would sometimes look better than 8K, and you really have to pick the right algorithm for the content you’re trying to upscale and compare quick previews before you commit. The important thing to know, though, is the images the computer spits out aren’t necessarily “truth” - it can invent details that aren’t there, or smudge ones that are, in the sometimes-inappropriate pursuit of clarity. I know, because I took it for a spin with a handful of anime music videos and game trailers myself, and was impressed just how easy it could be. For $299, the company will sell you an app that can spit out videos like these in a handful of hours, depending on your PC’s GPU, how long, and how high a resolution you need.

These enhancements are all made possible through a piece of software called Topaz Video Enhance AI, aka Topaz Gigapixel, and we’ve written a bit about it before - it’s the same generated adversarial network technique some modders are using to upscale the graphics of playable games themselves, now applied to their cutscenes as well.
