h.265 is a generic example of the state of the art in video compression. The distinction between 1080x1998 vs 1080x1920 is negligible. The point stands without the minutia.
When you double the resolution, the amount of data you're representing goes up by a factor of four. Businesses who double the resolution of their streams have not raised their data rates by a factor of four or even a factor of two, and the progress in encoding, while significant, has not been remotely sufficient. We're compressing more heavily than ever before because for some reason marketting can sell resolution at the edge of theoretical human perception, but not a fat data pipe well within human perceptual range.
- ska 11y agoYou're not wrong, but you have to be a bit careful with this line of reasoning when talking about compression, particularly: 4x the content in terms of pixels is not necessarily 4x the information content, and the latter is the real issue. Also worth thinking about. With transferring old film stock to digital, you have a potentially long pipeline of which compression is just that last step. I'd hesitate to blame all visual distortion (relative to the original) on compression without looking at it carefully.
