Movie Qualities (DvdRip,Br-rip,Bluray) formats

CAM
A copy made in a cinema using a camcorder or mobile phone. The sound source is the camera microphone. Cam rips can quickly appear online after the first preview or premiere of the film. The quality ranges from terrible to very good, depending on the group of persons performing the recording and the resolution of the camera used. The main disadvantage of this is the sound quality. The microphone does not only record the sound from the movie, but also the background sound in the cinema. The camera can also record movements and audio of the audience in the theater, for instance, when someone stands up in front of the screen, or when the audience laughs at a funny moment in the movie.

TELESYNC

A copy was shot in an empty cinema or from the projection booth with a professional camera mounted on a tripod, directly connected to the sound source. The professional camera source is then synchronized with audio source fed directly from the cinema's sound system, or captured from an FM radio transmission intended for hearing-impaired customers. Often, a cam is mislabeled as a telesync.

WORKPRINT

A copy made from an unfinished version of a film produced by the studio. Typically a workprint has missing effects and overlays, and often differ from its theatrical release. Some workprints have a time index marker running in a corner or on the top edge; some may also include a watermark. A workprint might be an uncut version, and missing some material that would appear in the final movie.

TELECINE
A copy captured from a film print using a machine that transfers the movie from its analog reel to digital format. These were rare because telecine machines for making these prints were very costly and very large. However, they have recently become much more common. Telecine has basically the same quality as DVD, since the technique is same as digitizing the actual film to DVD. However, the result is inferior since the source material is usually a lower quality copy reel. Telecine machines usually cause a slight left-right jitter in the picture and have inferior color levels compared to DVD

PAY-PER-VIEW-RIP

PPVRips come from Pay-Per-View sources. All the PPVRip releases are brand new movies which have not yet been released to Screener or DVD, but are available for viewing by hotel customers.

DIGITAL DISTRIBUTION COPY
DDC is basically the same as a Screener, but sent digitally (FTP, HTTP, etc.) to companies instead of via the postal system. This makes distribution cheaper. Its quality is lower than one of a R5, but higher than a Cam or Telesync.

R5
The R5 is a retail DVD from region 5 . Region 5 consists of the Indian Subcontient, Africa , North Korea, Russia and Monglia. R5 releases differ from normal releases in that they are a direct Telecine transfer of the film without any of the image processing. If the DVD does not contain an English-language audio track, the R5 video is synced to a previously released English audio track. Then a LiNE tag is added. This means that the sound often is not as good as DVD-Rips. To account for the lesser audio quality typically present in R5 releases, some release groups take the high quality Russian or Ukrainian 5.1 channel audio track included with the R5 DVD and modify it with audio editing software. They remove the non-english spoken portion of the audio and sync the remaining portion, which contains high quality sound effects and music with a previously recorded source of english vocals usually taken from a LiNE tagged release. The result of this process is an almost retail DVD quality surround sound audio track which is included in the movie release. Releases of this type are normally tagged AC3.5.1.HQ and details about what was done to the audio track as well as the video are present in the release notes accompanying the pirated movie.

The other regions are:

  • R0 - No Region Coding
  • R1 - United States of America, Canada
  • R2 - Europe, including France, Greece, Turkey, Egypt, Arabia, Japan and South Africa
  • R3 -Korea, Thailand, Vietnam, Borneo and Indonesia
  • R4 - Australia and New Zealand, Mexico, the Caribbean, and South America
  • R5 - India, Africa, Russia and former USSR countries
  • R6 - Peoples Republic of China
  • R7 - Unused
  • R8 - Airlines/Cruise Ships
  • R9 - Expansion (often used as region free)

R1 and R2 are considered the best quality.

DVD-RIP
A final retail version of a film, typically released before it is available outside its originating region. Often after one group of pirates releases a high-quality DVD-Rip, the "race" to release that film will stop. The release is an AVI file and uses the Xvid codec (earlier DivX) for video, and mp3 or AC3 for audio. Because of their high quality, DVD-Rips generally replace any earlier copies that may already have been circulating. Widescreen DVDs are indicated as WS.DVDRip.

DVD-R

A final retail version of a film in DVD format, generally a complete copy from the original DVD. If the original DVD is released in the DVD-9 format, however, extras might be removed and/or the video re-encoded to make the image fit the less expensive for burning and quicker to download DVD-5 format. DVD-R releases often accompany DVD-Rips. DVD-R rips are larger in size, generally filling up the 4.37 or 7.95 GiB provided by DVD-5 and DVD-9 respectively. Untouched or lossless rips in the strictest sense are 1:1 rips of the source, with nothing removed or changed, though often the definition is lightened to include DVDs which have not been transcoded, and no features were removed from the user's perspective, removing only restrictions and possible nuisances such as copyright warnings and movie previews.

HDTV OR DS RIP
TVRip is a capture source from an analog capture card (coaxial/composite/s-video connection). Digital satellite rip (DSR) is a rip that is captured from a non standard definition digital source like satellite. HDTV or PDTV or DTH (Direct To Home) rips often come from Over-the-Air transmissions. With an HDTV source, the quality can sometimes even surpass DVD. Movies in this format are starting to grow in popularity.

Analog, DSR, and PDTV sources are often re-encoded to 512×384 if fullscreen, 640×352 if widescreen. HDTV sources are re-encoded to multiple resolutions such as 640×352 (360p), 960×528 (540p), and 1280×720 (720p) at various file sizes for pirated releases. They can be progressive scan captured or not (480i digital transmission).

VODRIP
VODRip stands for Video-On-Demand Rip. This can be done by recording or capturing a video/movie from an On-Demand service such as through a cable or satellite TV service. Most services will state that ripping or capturing films is a breach of their use policy, but it is becoming more and more popular as it requires little technology or setup. There are many online On-Demand services that would not require one to connect their TV and computer. It can be done by using software to identify the video source address and downloading it as a video file which is often the method that bears the best quality end result. However, some people have used screen cams which effectively record, like a video camera, what is on a certain part of the computer screen, but does so internally, making the quality not of HD quality, but nevertheless significantly better than a Cam or Telesync version filmed from a cinema, TV or computer screen.

Similar to DVD-Rip, only the source is a Blu-ray Disc. A BD/BRRip in DVD-Rip size often looks better than a same-size DVD rip because encoders have better source material. A common misconception among downloaders is that BDRip and BRRip are the same thing. They differ in that a BDRip comes directly from the Blu-ray source, while a BRRip is encoded from a pre-release, usually from a 1080p BDRip from another group. BDRips are available in DVD-Rip sized releases (commonly 700 MB and 1.4 GB) encoded in Xvid, as well as larger DVD5 or DVD9 (often 4.5 GB or larger, depending on length and quality) sized releases encoded in x264.

BD5 or BD9 are also available, which are slightly smaller than their counterpart DVD5/DVD9 releases. They are AVCHD compatible using the BD folder structure, and are intended to be burnt onto DVDs to play in AVCHD compatible Blu-ray players. More recent types, probably associated with the use of newsgroups and cheaper storage at home, are complete Blu-ray copies. They are commonly referred to as BD25 or BD50 and may or may not be remuxed (but not transcoded). (Remixing is keeping the original video, but eliminating audio tracks, and/or adding audio tracks in other languages.)

BD/BRRIPS - BLURAY - BD5/BD9
BD/BRRips come in various versions: the m-720p (or mini 720p), which is a compressed version of a 720p and usually weighs around 2–3 GB; the 720p, which usually weighs around 4–7 GB and is the most downloaded form of BDRip; the m-1080p (or mini 1080p), which usually weighs a little bit more than 720p; and the 1080p, which can weigh from 8 GB to sizes as big as 40–60 GB. There are also mHD (or mini HD) versions available, which are encoded in lower resolution and are smaller in size.
