I downloaded the movie after seeing it in theatre to once again enjoy it from the comfort of my home. Seeing 2160p, I thought it's going to be a webcam rip but the title says webrip. Where is this leaked from that has Dolby Vision on a movie still in theatre?
if you have a good camera (2x number of pixels, and 2x colordepth than the movie), then you could make a camrip with perfect quality (assuming some calibration frames, and a cinema that gives no fuck). https://en.wikipedia.org/wiki/Nyquist%E2%80%93Shannon_sampling_theorem
though I guess that's still too much effort for most, and most early leaks are digital copies, as the other comments suggest.
edit: newer comments suggest camrip with a bad camera
Edit is incorrect
Would that be like on a tripod in the audience area recording the screen? Seems lossy somehow so I figure I'm misunderstanding. I'm pretty ignorant (~fully ignorant lol) about this, apologies, ya just piqued my curiosity.
yes.
it is! but that's where Shannon sampling theorem comes in. The sampling only needs to be twice as good as the source, and then you can reconstruct the source perfectly. (with some assumptions, e.g. correct color gamut, focal point, etc.).
Ahhh nice! Familiar with that via aliasing below Nyquist frequency, different words for the same idea.
Fun fact: this is how films get digitized, they play the film in a tiny movie theater just big enough for the camera. The whole apperatus is about the size of a washing machine
One of the ways…
Wtf lol, that just seems so...low tech? I certainly can't think of a "better" way to do it, guess I imagined some fully enclosed (or maybe that's what you're describing).
It's like finding out almost all power generation is really just different ways of boiling water lol
Scanner is technically the same, it just bounces light off the object, rather than shining through it.
Hell 3D scanning is pretty cool and what I'd consider high tech, but it's still just bouncing waves off things and recording those!
I guess there's no escaping the universal fundamentals, or the limits of our technology at least
