I have a Disney plus subscription through my family and watched a cool animation film yesterday. Sadly the horrible nitrate destroyed all the nice particle effects wich really took me out of the experience.
Are there any sites wich offer high quality streaming or should I look into torrenting for blue ray rips?
Any form of audio and video uses codecs. It applies to streaming websites as well. It's usually technological details that is not obviously disclosed to users for simplicity/convenience.
It's possible to inspect the stream and media, and find out what is being used. It may offer alternative streams, to support more efficient modern and less efficient older platforms.
