BDRip is the abbreviation for Blu-ray Disc Rip and consists of the extraction and encoding process on one video or film that is on a disk Blu-Ray. Files of this type are quite common and increasingly popular, with many being made available as a form of piracy.
A movie that is BDRip means that it was ripped from a Blu-Ray disc, and therefore has a high quality of audio and video, being far superior to DVDRip. Many of these movies are in AVI and MKV format and therefore can be played on DVD players that are not Blu-Ray compatible. These files can be very large, and can be 720p (1280 x 720 resolution), 1080p or 1080i (1920 x 1080 resolution). Usually files of this size do not fit on single-layer DVDs.
BDRip and BRRip have better quality than a file of the same size as DVDRip because their encoding has better source material (Blu-Ray disc). Many downloaders think that BDRip and BRRip are the same thing. The difference is that BDRip comes directly from Blu-ray, while BRRip is encoded from a previous source, usually a 1080 BDRip from another group. BDRips are typically 700MB and 1.4GB in size and encoded in Xvid. However, they can reach sizes larger than 4.5 GB, depending on the length of the video and the resolution (in case of videos in 1080p).
