DVDDVD stands for Digital Versatile Disc. It is the standard DVD disc which you would buy retail.
DVD ScreenerA DVD Screener is a promotional copy of a motion picture sent by a movie studios (on a DVD-Video disc) before the official DVD release date to movie critics, censors etc. The term DVDSCR is used by movie pirates to describe the source material of a bootleg SVCD, DivX, XviD or DVDR copy of a DVD Screener. These copies are usually of high, near-retail quality, but often contain some little extras on the video stream.
These extras includes timers, scrollers, black & white scenes, logos and serial numbers. The scrollers contain information about a few things, such as why some scenes of the movie appear in black & white, or have anti-piracy information that tell you how to contact anti-piracy groups if you have rented or purchased a DVD Screener copy of a movie. Serials are used to help track where the DVD Screeners were sent to (if they are copied and end up on the street or Internet) but these are usually blocked out completely by pirates.
Movie studios often also leave logos or watermarks on Screeners.
DVD-RipA DVD-Rip is a bootleg video ripped from a DVD source and then released on the Internet in a new container that is easily downloadable such as DivX, XviD, MP4 AVC, or more recently, MKV.
For the most part, DVD-Rips range from from 300MB in size (MP4 rips) to 1.36GB (2 CD releases with AC3 audio) with the larger releases with quality comparable to the full DVD it had been ripped from.
BLU-RAYBlu-ray is a name for a optical disc standard which uses blue-violet laser instead of red laser used in CDs and in DVDs. This allows manufacturers to store more data using the same amount of disc surface.
In fact, Blu-ray got its name from the technology, basically the "Blu" is from blue-violet diode and the "ray" is from optical ray. The "e" was intentionally dropped so that the full term "Blu-ray" could be registered as a new trademark.
BR-RIP or BDRipA BDRip/BRRip is a multimedia file that contains content that was sourced from a Blu-ray Disc product. As the "rip" part of the name applies, the copy is generally not a 1:1 copy, but instead is usually re-encoded. Most of the time Blu-ray disc rips (BDRips) contain AVC video that has a lower bitrate to the original content. Sometimes the creator of a BDRip may choose to lower the video resolution from Full HD 1080p content to 720p. The most common multimedia container used for BDRips is the Matroska (MKV) container, which would be used for its suitability.
R5R5 relates to a Region 5 DVD format created by the movie industry to help combat pirates, as well as tags used by movie pirates for distribution on the Internet. The movie industry created this format in efforts to help prevent piracy by producing higher quality Telecine transferred movies than pirates can offer on the Internet. This higher quality is achieved by the use of professional grade film transfer devices as opposed to lesser quality equipment obtainable by movie pirates.
R5 feeds in the form of pirated copies, have little to no remastering done to clean up the quality and usually never contain any special features. What this format allows potential bootleggers to do is release a DVD copy of a movie right around the time when a Screener is available on the Internet. Additionally, if an R5 DVD is released without an English audio Track, the direct line audio from the original film can be inserted and often tagged with .LINE in the finished filename.
There is currently no standard in the bootleg scene as to how R5 movies are labeled, therefore often files may be tagged as something familiar so as not to sway peers from downloading a specific group's offering. Names such as Telecines, DVD Screeners, or even DVD rips can be seen in place of the R5 tag that should be used on movies in this format. Several release groups have started using the R5 or R5 line tags to distinguish these files and urge other release groups to do the same to gain some standardization in the scene.

DVBDigital Video Broadcasting Project is an industry organization that develops technologies for the digital TV.
The three most widely used DVB's transmission protocols are DVB-C, DVB-S and DVB-T. All of these digital platforms are widely used, although mostly in Europe.
MP4MP4 is the official multimedia container for MPEG-4 video and audio. Although such video can be stored in a number of modern containers, including MPEG-2 PS/TS and Matroska, the development of MP4 is important because it gives hobbyists a replacement for the outdated AVI container which became the standard for MPEG-4 ASP (DivX, XviD, 3IVX, etc,...) video.
While MP4 works fine as a container format, it does have some issues that need to be resolved if its to become any kind of standard for hobbyists. Its primary problem is in audio support. Like the MPEG-2 container formats (Program Stream and Transport Stream) MP4 allows both native audio streams (encoded to a standard defined as part of MPEG-4) and private streams (those not part of the MPEG-4 specs). Unlike those formats, however, there's very little support among software and hardware vendors reading private streams. As a result, if your MP4 file contains audio in a format other than AAC there's a good chance your player won't be able to read it.
CAMCam method is basically just a guy who uses either regular or professional camcorder to shoot the movie either from TV or actually inside a movie theatre (in some Cam copies of movies you can actually hear and see audience).
TS [Telesync]One of the multiple terms used by movie pirates to describe the source material that was used to make a bootlegged pirate copy, normally distributed in VideoCD, SVCD or DivX format.
Precisely Telesync means a copy which was shot in an empty cinema or from the projection booth with a professional camera, directly connected to the sound source.
TC [Telecine]This term has two descriptions:
1) As movies are normally shot using 24.00fps framerate and American TV system, NTSC, uses framerate of 29.97fps, movie framerates need to be changed in order to get them play smoothly on TV.
This process, where studios add additional frames to the picture in order to increase the framerate, is called telecine. Process where various video editing tools reverse this process is called inverse telecine.
Technical details will be added later on.
2) Telecine also means a method to make an illegal bootleg copy of an original movie. Telecine method can be done in various ways, but normally it includes process where the movie is taken directly from the reel to digital format and then encoded into DVD-R, VCD, SVCD, DivX or XviD format.
VCDVCD stands for VideoCD (version 2.0 to be more specific). VideoCD is a standard developed in early 1990's that allows regular CD to contain 74 minutes of video and audio. Both, video and audio, are encoded in MPEG-1 format and stored on the CD in specific format.
VideoCDs can be played in most of the stand-alone DVD players, in all stand-alone VCD players and in all computers that have CD-ROM drive. This is the VCD's strong point against DivX format which is based on MPEG-4 audio/video encoding technology.
VideoCD resolution is in PAL format 352 x 288 pixels with 25 frames/second. In NTSC format it is 352 x 240 pixels with 29,97 frames/second (except in NTSC film format, where the framerate is 23,976 frames/second.
Audio is encoded with bitrate of 224 kbit/sec in MPEG-1 Layer2 format (in both PAL and NTSC versions). Video is encoded with bitrate of 1150 kbit/sec.
VHSRIPIn the Internet piracy scene, this term means a release of a movie, or some form of video, that has been taken from a VHS source. It has been captured and then re-encoded to a digital format. Some groups are dedicated to releasing VCD copies of movies that haven't been released on DVD as of yet.
TV-RIPTerm used mostly by Internet pirates to describe something that has been recorded from a subscription channel or from PRE-AIR Satellite feeds. PRE-AIR satellite feeds may have no channel logos on them but may have something small wrong with them like a slight flicker in the colours. Nearly every known current running series are released as TV-RIPs on the Internet by various release groups.
HDTVHDTV stands for High-Definition Television and as its name suggests, it specifies a higher resolution to the viewable TV image than the existing widely-used "standard" TV formats, such as NTSC and PAL.
Term HDTV is very often confused with the term DTV which simply stands for digital TV, but doesn't actually define higher resolution than the existing resolutions of PAL and NTSC. This "normal" DTV standard is widely used in Europe with normal PAL resolution of 704x576. European-wide standardization of HDTV specs is still largely under discussion and it is likely that Europe will switch to digital without actually changing the resolution to a higher one.
The specified HDTV resolutions that are used in United States and most notably in Japan, are called 1080i, 720p and 720i. HDTV's native aspect ratio is 16:9 -- same as with anamorphic DVD-Video discs, but in HDTV the resolution is "really" in 16:9 and not achieved by stretching the pixels to be wider, like in anamorphic DVD-Video discs.
HD-DVDHD DVD is the "next generation DVD" and has been standardized by the DVD Forum as its official "next generation" format.
Originally, the first "next gen format" to gain wide industry support was Blu-Ray, which was developed by Sony and Philips. However, due variety of reasons, Toshiba and NEC decided to bring their own format to the table, causing a similar situation to the next generation video format as the DVD-R and DVD+R caused to the recordable DVD media.
Anyway, HD-DVD is supported heavily by large companies such as Microsoft, but it still remains to be seen whether the format can have equal footing alongside Blu-ray.
HD-DVD uses blue-laser technology (just like Blu-ray does, opposed to DVD's red laser) and can fit approximately 15 gigabytes to one disc layer (compared to appx. 4.3 gigabytes on one DVD disc's layer).
HD-DVD's officially supported video and audio codecs aren't decided yet (late summer, 2005), but currently approved are the traditional MPEG-2, the high-quality MPEG-4 AVC and Microsoft's VC-1.
HD-DVD's maximum supported screen resolution according to its original specs was 1080i as opposed to Blu-ray's 1080p. This has been changed in later tech spec revisions, but early HD DVD players are limited to 1080i.
MKV [Matroska]Matroska's MKV "universal" Container is described by its developers as "the extensible open standard Audio/Video Container." This translates to a multimedia Container designed to support practically any type of video or audio stream you might care to use. MKV stands for Matroska Video. The project itself is simply called Matroska.
RMVBRMVB is a RealMedia Variable Bitrate file. RMVB is one of the newest file formats created by Real Networks and it has grown a pretty large following since its introduction due to its smaller file sizes yet still comparable quality when compared to other formats such as Xvid and DivX.
At one time RealVideo was a de facto standard for anime fansubs, which have been used by anime fans to distribute movies and TV shows to areas where they aren't otherwise available. RealVideo became popular because of its (then) superior quality at exceedingly low bitrates. That has changed however with the introduction of MKV, and other MP4 containers.
DTSDTS is a private company that develops audio formats, pretty much like Dolby. With term "DTS" people generally speaking refer to DTS's digital surround audio technology that is used widely on DVD-Video discs, just like Dolby's Dolby Digital/AC3.
