So, just how much do you really need to oversample your 4K footage? Sensor sizeīeyond the mere question of resolution, and what you do with it, though, is the canvas on which that resolution is captured. Still, you can already achieve that with 6K – cameras like the Panasonic S1H can already downscale 6K video to deliver an insane amount of detail. No, the real point of 8K at this moment in time is twofold: to provide enough resolution to crop into the frame (to frame close-ups in an interview, for example) or to produce oversampled 4K video – that is, 4K video that is downscaled from an ultra-dense 8K readout. Unless you're lucky enough to have an 8K display, you can't even watch 8K content yet. Of course, the fact of the matter is that 8K in and of itself isn't actually the point – at least, not in 2021. And to the all-important eyeball test, a 6K file is so pixel-rich that the perceptible gains of the extra 2K resolution really aren't that great. The fact is that 6K is already overkill in terms of resolution 8K is like bringing a grenade to a knife fight.
