It's common that when people want to download movies online they always see some abbreviations like webrip, BRRip_high, and some other stuff but don't know the meaning and sometimes end up with bad quality movies well I've compiled the meanings which I found online to help fellow nairalanders on their next trip to their respective download sites

BDRip (BluRay Disk Rip)
BDRips are encoded directly from the BluRay disk, so should be
of better quality than a DVDRip. They usually have a resolution
of 720p (or 1080p), and are encoded using the matroska (.mkv)
container and x264 codec.

DVDRip
A copy of the final released DVD. If possible this is released
PRE retail (for example, Star Wars episode 2) again, should be
excellent quality. DVDrips are released in SVCD and DivX/XviD.

R5
R5 refers to a specific format of DVD released in the Former-
Soviet Union, which is in DVD Region 5. In an effort to compete
with movie piracy, the movie industry chose to create a new
format for DVD releases that could be produced more quickly
and less expensively than traditional DVD releases. R5 releases
differ from normal releases in that they are usually a direct
Telecine transfer of the film without any of the image
processing common on DVD releases, and without any special
features. This allows the film to be released for sale at the
same time that DVD Screeners are released. Since DVD
Screeners are the chief source of high-quality pre-DVD release
pirated movies, this allows the movie studios to beat the pirates
to market. Bootlegged copies of these releases are often
distributed on the Internet via torrent sites.

PPVRip
PPVRips are said to have come from Pay-Per-View sources, but
what is interesting is that all these releases are brand new
movies which have not yet been released to Screener or DVD
but are available to view by Hotel customers.

TVRip
TV episode that is either from Network (capped using digital
cable/satellite boxes are preferable) or PRE-AIR from satellite
feeds sending the program around to networks a few days
earlier (do not contain "dogs" but sometimes have flickers etc)
Some programs such as WWF Raw Is War contain extra parts,
and the "dark matches" and camera/commentary tests are
included on the rips. PDTV is capped from a digital TV PCI card,
generally giving the best results, and groups tend to release in
SVCD for these. VCD/SVCD/DivX/XviD rips are all supported
by the TV scene.

WORKPRINT (WP)
A workprint is a copy of the film that has not been finished. It
can be missing scenes, music, and quality can range from
excellent to very poor. Some WPs are very different from the
final print (Men In Black is missing all the aliens, and has actors
in their places) and others can contain extra scenes (Jay and
Silent Bob) . WPs can be nice additions to the collection once a
good quality final has been obtained.

CAM
A cam is a theater rip usually done with a digital video camera.
A mini tripod is sometimes used, but a lot of the time this wont
be possible, so the camera make shake. Also seating placement
isn't always idle, and it might be filmed from an angle. If
cropped properly, this is hard to tell unless there's text on the
screen, but a lot of times these are left with triangular
borders on the top and bottom of the screen. Sound is taken
from the onboard microphone of the camera, and especially in
comedies, laughter can often be heard during the film. Due to
these factors picture and sound quality are usually quite poor,
but sometimes we're lucky, and the theater will be fairly empty
and a fairly clear signal will be heard.

TELESYNC (TS)
A telesync is the same spec as a CAM except it uses an external
audio source (most likely an audio jack in the chair for hard of
hearing people). A direct audio source does not ensure a good
quality audio source, as a lot of background noise can interfere.
A lot of the times a telesync is filmed in an empty cinema or
from the projection booth with a professional camera, giving a
better picture quality. Quality ranges drastically, check the
sample before downloading the full release. A high percentage
of Telesyncs are CAMs that have been mislabeled.

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. A great example is the JURASSIC PARK
3 TC done last year. TC should not be confused with TimeCode ,
which is a visible counter on screen throughout the film.

SCREENER (SCR)
A pre VHS tape, sent to rental stores, and various other places
for promotional use. A screener is supplied on a VHS tape, and
is usually in a 4:3 (full screen) a/r, although letterboxed
screeners are sometimes found. The main draw back is a
"ticker" (a message that scrolls past at the bottom of the
screen, with the copyright and anti-copy telephone number).
Also, if the tape contains any serial numbers, or any other
markings that could lead to the source of the tape, these will
have to be blocked, usually with a black mark over the section.
This is sometimes only for a few seconds, but unfortunately on
some copies this will last for the entire film, and some can be
quite big. Depending on the equipment used, screener quality
can range from excellent if done from a MASTER copy, to very
poor if done on an old VHS recorder thru poor capture
equipment on a copied tape. Most screeners are transferred to
VCD, but a few attempts at SVCD have occurred, some looking
better than others.

DVD-SCREENER (DVDscr)
Same premise as a screener, but transferred off a DVD.
Usually letterbox , but without the extras that a DVD retail
would contain. The ticker is not usually in the black bars, and
will disrupt the viewing. If the ripper has any skill, a DVDscr
should be very good. Usually transferred to SVCD or DivX/XviD.
VHSRip
Transferred off a retail VHS, mainly skating/sports videos and
Bleep 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. Common groups are
SMR and TND. These aren't really worth downloading, unless
you're that unsure about a film u only want a 200mb copy of it.
Generally avoid.

Watermarks
A lot of films come from Asian Silvers/PDVD (see below) and
these are tagged by the people responsible. Usually with a
letter/initials or a little logo, generally in one of the corners.
Most famous are the "Z" "A" and "Globe" watermarks.

Asian Silvers / PDVD
These are films put out by eastern bootleggers, and these are
usually bought by some groups to put out as their own. Silvers
are very cheap and easily available in a lot of countries, and its
easy to put out a release, which is why there are so many in the
scene at the moment, mainly from smaller groups who don't last
more than a few releases. PDVDs are the same thing pressed
onto a DVD. They have removable subtitles, and the quality is
usually better than the silvers. These are ripped like a normal
DVD, but usually released as VCD.

And finally

This is a file ripped from a DRM-free streaming service,
such as Hulu, Crunchyroll or WWE Network. The quality is
sometimes comparable to WEB-DL, but bitrates are usually
lower to save on streaming bandwidth. The file is often
extracted from the RTMP protocol and losslessly remuxed
from an MP4 or FLV container to MKV.
