- speedgoose 5y agoCinemas don't use consumer grave video compression like h265, instead each frame is a jpeg 2000 image. It's heavy.
- KaiserPro 5y agoTo simplify its a tar with jpeg2000s as an image stream, plus audio and some metadata. Its then (usually, but it is optional) encrypted to make sure that its hard to copy. The keys are sent directly to each projector to allow time limited, and or other limited use. The reason why its used is because it optimized for quality, rather than size. It also allows custom colour spaces and other tweaks to maintain/enforce colour correctness/image quality.
