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 won’t be possible, so the camera may 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.
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.
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. TC should not be confused with TimeCode , which is a visible counter on screen throughout the film.
TC：英文TELE CINE，TC（telecine）使用电视电影机从胶片直接数字拷贝，其图象和声音质量应该很好。但由于使用的设备和费用很高，TC很少见。通常会使用正确的高宽比，但有时也有 4:3的TC。侏罗纪公园III是一个很好的例子。不应将TC这个名词和TimeCode(时间码)混淆，时间码是一个在屏幕上可见的计数器。
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 s*rial 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 through 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.
SCREENER(SCR)是在电影发行VHS录象带之前送到录象出租店及其他地方用做促销目的。SCREENER使用VHS录象带，通常使用 4:3（全屏）的高宽比，但有时也会有LETTERBOXED(1.85:1宽银幕) SCREENER. 主要的缺点是有“TICKER”（在屏幕下方滚动的消息，包含版权和反盗版电话号码）。同时，如果录象带包含任何序列号或可以导致查出录象带来源的记号，这些记号必须被遮掉，通常使用一个黑斑遮住上述部位。有时这些记号只出现几秒钟，有时也可能不幸在怎个电影中出现，而且有时会很大。根据使用的设备， SCREENER的质量可能是极好，如果是从原版拷贝；也可能很差，如果是从翻录的拷贝录制，同时又使用很烂的捕捉设备和录象机。大多数的 SCREENER被转制成VCD，现在也出现了SVCD；有些看起来比另一些好。
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.
A copy of the final released DVD. If possible this is released PRE retail. again, should be excellent quality. DVDrips are released in SVCD and DivX/XviD.
Transferred off a retail VHS, mainly skating/sports videos and XXX releases.
These are the first releases usually available on a TV show since they are encoded while the program airs, unlike the other release formats. Sometimes they are even from the feed to local stations and therefore available before it airs on tv.
The quality of these releases vary, but are generally pretty low since it is VCD, and widescreen shows (that includes the black lines, so it doesn’t leave many lines for the actual video). The only advantage to this format is that it is available fast and it plays on all the standalone dvd players but if you have something that supports xvid go for one of the formats below if possible.
Postair rips from an analogue source but the image quality is generally very good and they are encoded in xvid.
TVRip：从电视（最好是从数码有线电视/卫星电视捕捉）转制的电视剧，或接收由卫星提前几天向电视网传送的预播节目（不包含加密但有时有雪花）。有些节目，比如 WWF RAW IS WAR包含多余的部分；”DARK MATCHES”和CAMERA/COMMENTARY测试被包含在TVRip里。PDTV是从PCI数码电视卡捕捉，通常效果最好；破解组织倾向于使用SVCD来发布。VCD/SVCD/DivX/XviD rips也都被用于发布TVRip。
* DSRip (Digital Satellite)
Postair rips from a digital satellite transmission, very good quality and they are encoded in xvid.
* PDTV (Pure Digital TV)
Postair rips from a pci TV card that supports digital TV. This and HDTV are the most common formats and the quality is excellent. They are encoded in xvid.
* HDTV (High Definition TV)
Postair rips from a pci tv card that supports HDTV which is broadcasted digitally and at a very high resolution although it is encoded in about the same resolution as PDTV releases depending on the release groups so there won’t be a huge difference in quality between them, most networks are broadcasting in this format and it is encoded in xvid.
A workprint is a copy of the film that has not yet been finished. It can be missing scenes, music, and quality can range from excellent to very poor. Some WP’s are very different from the final print (‘Men In Black’ in it’s time for example was missing all the aliens, and had actors in their places (kinda funny though!)) and others can contain extra scenes. WP’s can be nice additions to the collection once a good quality final has been obtained.
WORKPRITN (WP)是从未完成的电影拷贝转制而成，可能会缺失镜头和音乐。质量可能从最好到很差。有些WP可能和最终版本相差很远。(MEN IN BLACK的WP丢失了所有的外星人，代之以演员)；另一些则包括多余的镜头(Jay and Silent Bob). WPs可以作为有了好质量的最终版本后的附加收藏。
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.
