The developer of Unrecord should never have shown off what he made or how he did it. The market is already flooded with this stuff, to the point that if Unrecord ever actually releases, the novelty of its style will be lost in the sea of mediocrity.
What is Unrecord really doing that's special? It just looks super realistic; which is mostly due to Unreal 5 and these hyper-realistic graphics were shown in other tech demos like The Matrix city or the Japanese train station demos.
Camera movement and perspective can have a huge impact on selling the images as "real". You can have a drone hover over a race car, and it will look fake, because your brain tells you it's a video game; "Here's to You" from the beginning of MGSV: Ground Zeroes still looks better than most cut-scenes because it emulates a person holding a camera.
It's definitely neat, and I think I'd be into it for a game like STALKER, but I think too much of CP2077's art direction and visual identity is lost with this. Cool to see, though, still.
It's kinda crazy how just by getting the camera movement, lens distortion, and exposure settings just right, you end up with a very natural-looking video. Even the game textures and animations end up looking more convincing this way. This might be a really fun way to play a stealth build.
