For those who like to download box office film, documentary film, etc from the sharing site on the internet this terminology (CAM, TS, TC, DVDscr, Rip, etc) is very common. So What is that anyway ? So here is the explanation:
If you ever see a film that sometimes the audience suddenly appear in the film, that is the Cam-Quality film. A Cam is a theater rip usually done with a digital video camera. Sometimes they use mini tripod, but a lot of them do this manually so the camera make shake. And sometimes the seating placement isn’t always idle, it might be filmed from an angle. The sound is taken directly from the onboard microphone of the camera, so sometimes you can hear the audiences laughter quite often during the film. Due to these factors the sound and picture quality usually very poor.
Actually it’s similiar with CAM but TS is filmed with different condition it uses an external audio source (most likely an audio jack in the chair for hard of hearing people), but it does not ensure a good audio quality though. And TS is filmed in an empty cinema or from the projection booth with a professional camera, giving a better picture quality.
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. Sometimes it shows a visible counter on screen throughout the film
Typically these are high quality Telecines intended for the East European market (released in Russian language only) to combat piracy in that region. Ironically, these movies then have the English audio track from another source (such as a CAM) dubbed over them and get released. Until recently these releases have been tagged as R5 but we're starting to see similar sources from other regions tagged as R3 or R6. The number is derived from the DVD region the source came from.
A pre VHS tape, sent to rental stores, and various other places for promotional use. 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.
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.
R5 RETAIL (R5)
Over the past 6 months the major movie studios have been releasing retail dvds early in Russia. They do this to stop the widespread use of pirated telecines (which were once very common). Lately however there has been very few real telecines, most of the scene telecines you see are actually R5 retails. The main difference between telecines put out by the pirates is that the r5’s are done using pro equipment, professional studios and professional people. The quality of R5 retail is very similar to dvdscr’s, no time is usually spent cleaning up dvdscrs either.
Region 3 is from Southeast Asia and East Asia (including Hong Kong) The quality of R3 retail is very similar to dvdscr's.they must use a TS or a cam English audio rip because there high quality audio would only be in a Region 3 language.
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.
So if you want to download a film with good quality, both sound and the picture, I think you should be patience until the DVD RIP is come out
The range of quality we now have is like this.
R1/2 retail > DVDRIP > R5 Retail > DVDSCR > Telecine > Telesync > Cam.
BDRip or Blu-Ray Rip
Copies made from Blu-Ray Discs. These have better quality than DVDRip and the resolution is 1080p or 720p. For the same reasons the file sizes too will be double or three times that of a dvdrip.
720P are 1280X720 but most of them are 1280X544 or 1280X688
Audio can be in Dolby Digital 2.0,5.1 and DTS 5.1,6.1,DTS ES 7.1
size can be anywhere between 4.37GB up to 9GB
1080P are 1920x1080 and there about 1920x800 or 1920x1040
Audio can be in Dolby Digital,5.1 and DTS 5.1,6.1,DTS ES 7.1
size can be anywhere bet ween 8GB up to 14GB or more.
Some of yo u might say why do some blu ray mkv videos have the dimensions of 1280X544 or 1280X688 , etc. but are still in 720p? Shouldn't they be in 1280X720?
They are at that resolution because the black bars have been cropped off. Unless you are dealing with anime chances are that the videos will have black bars and depending on the encoder he/she can opt to either keep the black bars or crop them off.
Transferred off a retail VHS, mainly skating/sports videos and XXX releases.
TV episode that is either from Network (capped using digital cable/satellite boxes are preferable) or PREAIR
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 part s, 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.
These versions are captured from HDTV (High Definition TeleVision) broadcast sources. Again the quality is much better than DVDrip because of higher resolution. It is comparable with blu-ray rip.
This is Pay Per View Rip, from a hotel service etc. If its taken direct from source, it will be DVD quality, but if its filmed from the hotel room using a mobile phone or camera, then its a CAM. Pretty much the same rules apply here as VODRip.
Web Rip is usually when a movie is streamed on a website, or even movie on demand hosts, such as Lovefilm or Netflix etc and is saved directly to a hard-disk using specialist software, uploaded and shared. It is the same as a VODrip but the host of the movie may be a web only service. It should be the same quality as a DVDrip as its taken from source. However, some people take a TS of a WEBrip and still call it a WEBrip, its not its a CAM or TS. Any use of CAM or TS should be titled as such. If the original webcast is a TeleSync and its downloaded and shared, its still a TeleSync (TS) and not a WEBrip. WEBrip's are becoming more and more common as they are very vague. WEBrip doesnt really give you a clue to its source. A true WEBrip would be from say Netflix, but since Netflix movies are way after release dates, this is not the case nowadays. So usually, someone will film a movie using TS, share it on a streaming website. Then whoever downloads the stream and shares it, calls it a WEBrip, as they did indeed rip it from a streaming site. However, the source is still a TS, so it should be labelled as such. If you see a WEBrip that is NOT dvd quality, then its probably a HDTS, HDCAM, TS or CAM.
Video-On-Demand Rip - This is a recording of a video/movie from an On-Demand service such as through a cable or satellite TV. A VODrip should be the same quality as a DVDrip as its taken from source, effectively like saving something to Sky+ and sharing the file from the drive. However, some people take a TS of a VODrip and still call it a VOD rip, its not its a CAM or TS. Any use of CAM or TS should be titled as such. For instance, filming a Video On Demand using your mobile phone, is not a VODrip, its a CAM.
This is the movie studio's first cut of the project, often before it has got to the publisher. Although the quality is usually DVD quality, it is unfinished. So it may not include any CGI (which is later put in by Special FX dept) or may include different or working camera angles. You may see stuntmen instead of actors, and you may also see props that will be removed after editing. Not the best way to watch a film, but can sometimes be 'eye opening' as we never expect to see a film in this way. The most famous Workprint leak to date was the X-Men Wolverine movie which was leaked months before the film was released. It included the wires holding the actors up when they were doing their stunts and the CGI was just greyscale as it was unfinished. If you get the chance, The Wolverine workprint is worth watching just to see how a raw movie looks before it hits their studio's Special FX dept.
Due to scene rules, whoever releases the first Telesync has won that race (for example). But if the quality of that release is fairly poor, if another group has another telesync (or the same source in higher quality) then the tag PROPER is added to the folder to avoid being duped. PROPER is the most subjective tag in the scene, and a lot of people will generally argue whether the PROPER is better than the original release. A lot of groups release PROPERS just out of desperation due to losing the race. A reason for the PROPER should always be included in the NFO.
A limited movie means it has had a limited theater run, generally opening in less than 250 theaters, generally smaller films (such as art house films) are released as limited, films (such as art house films) are released as limited.
An internal release is done for several reasons. Classic DVD groups do a lot of .INTERNAL. releases, as they wont be dupe'd on it. Also lower quality theater rips are done INTERNAL so not to lower the reputation of the group, or due to the amount of rips done already. An INTERNAL release is available as normal on the groups affiliate sites, but they can't be traded to other sites without request from the site ops. Some INTERNAL releases still trickle down, it usually depends on the title and the popularity.
If a group releases a bad rip, they will normally release a Repack which will fix the problem. The reason for the repack should be stated in the .nfo
A release can be nuked for various reasons. Individual sites will nuke for breaking their rules (such as "No Telesyncs") but if the film has something extremely wrong with it (no soundtrack for 20mins or missing the ending for example) then a global nuke will occur, and people trading it across sites will lose their credits. Nuked films can still reach other sources such as p2p/usenet, but its a good idea to check why it was nuked first in case. If a group realise there is something wrong, they can request a nuke.
NUKE REASONS :: this is a list of common reasons a film can be nuked for (generally DVDRip)
** BAD A/R ** :: bad aspect ratio, ie people appear too fat/thin
** BAD IVTC ** :: bad inverse telecine. process of converting framerates was incorrect.
** INTERLACED ** :: black lines on movement as the field order is incorrect.
Xvid is a primary competitor of the DivX Pro Codec (Xvid being DivX spelled backwards). In contrast with the DivX codec, which is proprietary software developed by DivX, Inc., Xvid is free software distributed under the terms of the GNU General Public License. This also means that unlike the DivX codec, which is only available for a limited number of platforms, Xvid can be used on all platforms and operating systems for which the source code can be compiled.

x264 is a free software library for encoding video streams into the H.264/MPEG-4 AVC format. It is released under the terms of the GNU General Public License. x264 is typically used for encoding high definition video. Typically from HDTV or Blu-Ray. x264 files are also further denoted by either 720p or 1080p tags, which is the vertical resolution of the image. HDTV rips are normally 720p format whereas Blu-ray rips are often released in both 720p and 1080p (the latter requiring significantly more processing power to decode but offering a higher resolution).
HEVC stands for high-efficiencyvideocoding. Also known as H.265, this new video codec will compress video files to half the size possible using the most-efficient current encoding format, MPEG-4, aka H.264 (used on Blu-ray discs and some satellite TV broadcasts). That will be one-quarter the size of files compressed using the MPEG 2 codec that most cable-TV companies still employ. More importantly, HEVC is used to compress video with 4K resolution — and possibly even 8K resolution in the future — so it can be efficiently delivered.
Is the recordable DVD solution that seems to be the most popular (out of DVD-RAM, DVD-R and DVD+R). it holds 4.7gb of data per side, and double sided discs are available, so discs can hold nearly 10gb in some circumstances. SVCD mpeg2 images must be converted before they can be burnt to DVD-R and played successfully. DVD>DVDR copies are possible, but sometimes extras/languages have to be removed to stick within the available 4.7gb.
Scene rules require the releasing group to spread theatrical VCDs in .bin/.cue files that can be burned on a CD. Although often the CD size is dictated by the length of the movie or video. One movie typically uses two CDs, although length may force the release to be a 3 or 4 CD release. The source of these theatrical releases is typically analog, such as CAM, telecine or telesync releases (movies recorded by a camera in theatres, often with external audio sources). VCDs from other sources such as DVD, VHS, TV, Pay-Per-View specials, Porn or Anime may also be released in the .mpg or .asf format. DVD and VHS rips are only allowed if there was no screener released before. The first VCDs popped up in 1998. FTF and Immortal VCD are two groups that have released VCD movies.Because of its low quality, VCD releases declined in favor of SVCD and XviD. VCDs are often larger than these higher quality files, making VCDs even less attractive. VCDs once used for music videos got their own set of standards on October 1, 2002.
Scene rules require the releasing group to spread SVCDs in .bin/.cue files, that fit on 700 MiB CDs. One movie typically uses two CDs, although length may force the release to be a 3 or 4 CD release. Content source is sometimes analog, such as Cam, Telecine or telesync releases. Also R5, DVDSCR or retail DVD is used as SVCD source. The advantage of SVCD is that it can be played on any standalone DVD player, but when DivX-capable players are taking over the market and more bandwidth becomes available to download DVDRs, SVCD became obsolete. Around 2007, the stream of SVCD releases from the scene died out
PDTV (Pure Digital TV)
Other resolution digital recordings from source streams at a bitrate of 10+mbps or higher. It is a label given to files that were ripped directly from a purely digital source, having less resolution than HDTV. This is accomplished by using a TV tuner card capable of receiving Digital Video Broadcasts or C-Band. Encoded in XviD.
SDTV (Standard Digital Television)
Digital recording or capture from a source stream at any resolution with bitrate under 10mbps.This includes DirecTiVo but also captures from digisat or digicable with analog capture cards.
Hardcoded means the subtitles is etched on to the movie which cannot be disabled as it is a part of the movie.
As the name suggest this is recorded using a HD camcorder, but instead of low end cam with low resolution or aspect ratio, HDCAM quality are nevertheless significantly better than a CAM version filmed from a cinema, TV or computer screen.
It’s very likely that you will find one of these files with every movie you get. It’s bacically used to promote the ripper and provide information about the release. It will include movie source, file size, codecs used and movie and cast description. If you face trouble viewing these files on Windows, just open them in Notepad or other text editors.
