We have such a thing as an 8K camera. It's kinda hard to beat an 8K camera. Especially given film has a very low frame rate, so you're trading one kind of quality for another.
8K is basically more pixels than your ever going to need unless you like staring at a tiny portion of the screen. 24 FPS (films normal FPS fyi) on the other hand is very noticeably different from 60 FPS, nevermind the 120+ FPS some cameras can do.
The reason we have these cameras is partly so we can crop and still get a usable 4K or 6K image.
As for compression we have true lossless and visually lossless formats that are used on professional video cameras. This includes Red Raw.
Did I mention that this kit is cheap enough that Linus Tech Tips - a YouTube channel - can afford to have at least one.
