Sometimes it can be difficult to distinguish the difference between all of the different releases of something... So, I decided that I will put together a guide to let you know what each release is, and what the abbreviations stand for. Hope this helps some of you, and I didn't see it anywhere else, so here we go.
Cam - Obviously, this is the first copy you generally find once a movie is out in theaters. It is a copy of someone using a camcorder inside of a movie theater. The sound comes from the camcorder's microphone, and is usually less than optimal (to say the least).
Telesync - TS, PDVD - A telesync copy is often misunderstood by people. Telesync has nothing to do with picture quality, but rather, audio quality. Usually the video is from a cam copy, with the sound recorded later on and synced with the video.
Workprint - WP - I don't normally see a lot of these out, but it is basically an unfinished release of the movie. Sometimes it doesn't contain all of the special effects that the final copy will.
Screener - DVDSCR, SCREENER, SCR, DVDSCREENER - A screener is a copy of the finished product, which has been sent to academy judges and other people for review. You can sometimes read words on the bottom saying that it is only for those people, with a phone number to call (yeah right...)
R5 - Retail DVD release from Region 5, which includes Eastern Europe, Indian Subcontinent, Africa, North Korea, and Mongolia. If the copy isn't in the language ie english, usually there will be a copy of a previous release's audio synced with the R5 video.
DVDRip - Usually the grand-poo bah of pirated movies until the actual retail version comes out. This is generally a copy of the retail version distributed to a region it has not been released to yet.
DVDR- This is the final copy, what you would buy in a store.
BD/BR rip - Blue Ray copy of the DVDrip or DVDr
HDTV - High definition version of the previous copies.
Thanks to Reducto for the following...
Telecine - TC - A telecine machine copies the film digitally from the reels. Sound and picture should be very good, but due to the equipment involved and cost telecines are fairly uncommon. Generally the film will be in correct aspect ratio, although 4:3 telecines have existed.
VHSRip - Transferred off a retail VHS, mainly skating/sports videos and XXX releases.
DivX Re-Enc - A DivX re-enc is a film that has been taken from its original VCD source, and re-encoded into a small DivX file. Most commonly found on file sharers, these are usually labeled something like Film.Name.Group(1of2) etc.
Thank you to wikipedia for some of this information. If I've left anything out that is important, let me know. And if this is a duplicate of a thread already created, feel free to delete it. I didn't see one... Hope this helps some of you :)
