Interesting. 4K is mostly a lie.

@Gargron without looking, is this about compression? Because yeah. JPEG lossy compression works on images as well as words (LLMs)

@codinghorror @Gargron

Well, yes and no. The full argument was that:

- most of the digital film cameras are recording at less than 4k (2.4k was used as a median).
- those that use film, get digitalised before cutting for that ~2.4k, and that's the resolution on which efects are added, and which forms the defacto max-resolution.
=>so what they sell as 4K is often only 2.4k, with stretched pixels.

Further: to stream those streched extra-pixels, they tend to over-compress colour profiles.

@iju @codinghorror @Gargron yeah, streaming (as opposed to 4k Blu-ray) has effectively made 4k TVs pointless. They mostly target 15mb/s and most of the detail is lost. Same goes for the Dolby Vision dynamic HDR profiles they use for streaming.

Stick a high bitrate Blu-ray of a decent film transfer on a well calibrated display and you’ll be blown away, though.

@WiteWulf i’ve seen remuxes of 1080p videos and 4k and I honestly cannot tell them apart sitting at an appropriate distance on my 75 inch TV
