WEB-DL (P2P) refers to a file losslessly ripped from a streaming service, such as Netflix, Amazon Video, Hulu, Crunchyroll, Discovery GO, BBC iPlayer, etc., or downloaded via an online distribution website such as iTunes. The quality is quite good, since they are not reencoded. The video (H.264 or H.265) and audio (AC3/AAC) streams are usually extracted from the iTunes or Amazon Video and remuxed into a MKV container without sacrificing quality.
