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–Shannon_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
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.).
