Difference between 1080p, 480p, 720p, Blueray, BRRIP, CAM, DVDrip, DVDSCR, Hdrip, HDTS, HDTV and WebRip | Detailed Explanation .
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 won't be possible, so the camera makes a 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 time 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. The 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 the correct aspect ratio, although 4:3 telecines have existed. A great example is the JURASSIC PARK 3 TC done a few years ago. 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 drawback 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)
The 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.
DVDRip
A copy of the final released DVD. If possible this is released PRE retail again, should be of excellent quality. DVDrip are released in SVCD and DivX/XviD. 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 used to be indicated as WS.DVDRip.
VHSRip
Transferred off a retail VHS, mainly skating/sports videos and modes releases.
HDTV
HDTV or PDTV or DTH (Direct To Home) rips often come from Over-the-Air transmissions. 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). With an HDTV source, the quality can sometimes even surpass DVD. Movies in this format are starting to grow in popularity.
TVRip
A 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.
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(hosting site) 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.
R5
The R5 is a retail DVD from region 5. Region 5 consists of India, Africa (except Egypt, South Africa, Swaziland, and Lesotho), Russia, and former USSR countries. R5 releases differ from normal releases in that they are a direct Telecine transfer of the film without any of the image processing.
WEB – DL
This is a movie or TV show downloaded via an online distribution website (web download), such as iTunes. The quality is quite good since they are not re-encoded. The video (H.264) and audio (AC3/AAC) streams are usually extracted from the iTunes file and then remuxed into an MKV container without sacrificing quality. An advantage with these releases is that they mostly have no network logos on the screen, just like BD/DVDRips.
WEBRip
This is a file ripped from a DRM-free streaming service, such as Hulu, Crunchyroll or WWE Network. The quality is comparable to WEB-DL, but bitrates are lower to save on streaming bandwidth. The file will be extracted from the RTMP protocol and losslessly remuxed from an MP4 or FLV container to MKV.
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 it's 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. DVDs 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.
BRRIP and BDRIPs
Blue-Ray BRRIP’s and BDRIP’s have been around for quite some time. These two are remarkable in the sense that they’re compatible with standalone home DVD players (with DivX/XviD support), XBOX 360, PS3, and other external peripherals.
These BRRip XviD and BDRip XviD files allow anyone to burn HD-quality Blu-Ray ripped movies on regular DVD media, and playback on most conventional DVD players – without the headaches of re-encoding or DVD authoring. There’s just one catch – you’ll likely need an HDTV to take full advantage of the superior video quality.
BRRip
An XviD encode from a Blu-Ray release (i.e. a 1080p *.mkv file). A BD/BRRip in DVD-Rip size often looks better than a same-size DVD rip because encoders have better source material.
BDRip
An XviD encodes directly from a source Blu-Ray disk. A common misconception among downloaders is that BDRip and BRRip are the same things. 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 or x264, as well as larger DVD5 or DVD9 (often 4.5 GB or larger, depending on length and quality) sized releases encoded in x264.
While both BRRips and BDRips are superior to DVDRips, they are normally released in 720p resolution, since standalone DivX (*.avi) players do not support anything higher than this anyways. They should not be confused with genuine Blu-Ray rips in 1080p, which are usually done in native Blu-Ray files, or as H.264 *.mkv files.
First, understand what is resolution and pixel density :
Think of your TV screen as a grid, having pixels in rows and columns. Now if the resolution is 720p, that means it has 720x1280 pixels.
This further means that 720 pixels across the screen rows and 1280 pixels down the screen as columns.
Based on this resolutions are defined as Np where N is pixels across the width, and p stands for progressive scan, i.e. non-interlaced.
Standard Definition standards -
480p - 480 denotes a vertical resolution of 480 pixels, usually with a horizontal resolution of 640 pixels and 4:3 aspect ratio (480 × 4⁄3 = 640)
560p - DVD quality for SD formats
High Definition standards -
HD displays are measured in terms of the pixels going across the screen in width having an aspect ratio of 16:9
1080p - resolution of 1920x1080 (2.1 megapixel)
4K or UHD - resolution of 3840 pixels × 2160 lines(8.3 megapixels,
Formats for storing / streaming / recording / distributing HD media-
BlueRay - Its a DVD format for the storage of HD and UHD video and data, designed to supersede the DVD format, called BD (BlueRay disk)
BDRip - a term used for the same format encoded directly from the BluRay disk, not equivalent to BD but better than DVD in 720p/1080p formats
CAM rip - Its a movie recorded in theater; also called theater rip usually done with a digital video camera
DVDRip - Copy of movie ripped from DVD having similar or lesser resolution
HDRip - ripped from HD movie
HDTS - Its a ripped HDCam copy with line audio
HDTV - movie recorded from content aired on HD television
WebRip - Content ripped from a non-DRM streaming service, such as Hulu, Crunchyroll or WWE Network. Similar quality as WEB-DL
Rip is the process of copying audio or video content to a hard disk.
HD: High Definition
Pre-release types:
R5: The R5 is a retail DVD from region 5. Region 5 consists of Russia, the Indian subcontinent, most of Africa, North Korea, and Mongolia.
SCR(Screener ): A Screener is usually recorded from a promotional videotape or DVD which is sent to censors and film critics etc.. The quality is usually as good as a commercial product, sometimes a copyright message appears on the screen. Labels are SCR, SCREENER, DVDSCR, DVD SCREENER, BDSCR.
TC(TeleCine): The term telecine refers both to a film-to-tape transferring machine, as well as the process by which film is transferred to tape. Labels are TC, TELECINE.
WP(WorkPrint): Each frame of the film is copied from celluloid (or another source), these are sometimes incomplete movies. The sound is usually perfect and the visual quality can vary. Labels are WP, WORKPRINT.
In-cinema types:
Cam: This type of VCD was recorded by someone in a cinema with a camcorder. The picture quality and sound varies from OK to poor. Labels are CAMRip, CAM.
TS(TeleSync ): Also recorded in a cinema but usually with a high-end camera and a separate audio source; These are generally decent to good quality. Labels are TS, TELESYNC, PDVD.
Home video ripping
TVRip: Is a capture source from an analog capture card. Labels are DSR, DSRip, SATRip, DTHRip, DVBRip, HDTV, PDTV, TVRip, HDTVRip.
DVD-Rip: A final retail version of a film.
BluRay/BD/BRRip: This is a movie ripped directly from a Blu-ray disc.
WEBRip: Is downloaded from internet streaming services, the quality is like a normal DVD-Rip. But sometimes they come with Korean subs hardcoded.
1080p - 1080 lines of vertical resolution i.e. 1080 pixels per horizontal line, p stands for Progressive scan. If we consider resolution 1920x1080 resolution, there will be 1080 pixels per each of the 1920 vertical lines, giving us a total of 1920*1080 = 2073600
720p - 720 lines of vertical resolution
480p - 480 lines of vertical resolution
Blu-Ray - It is nothing but an optical disk that is capable of storing large amounts of data that are typically required for 1080p resolution files, (now even 4k which is nothing but a resolution of 4096x2160). Which is 25GB for single layer and 50GB for dual-layer
The various Rips are the pirated versions compressed further to reduce their size. They are just taken from the discs and converted to the typical formats such as .avi or .mkv
BRRip - Taken from a Blu-Ray disc
CAM- Copy created by shooting the movie in the theatre with a camera.
DVDRIP - Copy ripped from DVD
DVDSCR - It is an advanced video or DVD copy of a film sent to critics, awards voters, video stores (for their manager and employees), and other film industry professionals, including producers and distributors. Often, each individual screener is sent out with distinct markings (such as a digital watermark), which allow copies of a screener to be tracked to their source.
HDTS - Usually content digitally streamed content Shot with the camera.
HDRip/HDTV/Webrip - High Definition original digitally streamed content recorded and ripped.
1080p/720p/480p: the number represents the number of horizontal lines the video has from top to bottom while the p stands for progressive scan.
A 480p video is made up of 480 lines stacked one on top of another, with each line being 852 pixels wide – that’s what it means when people say a video’s resolution is 852×480. Accordingly, a 720p video has 720 lines that are each 1,280 pixels wide, meaning that it is more than twice as sharp as a similar 480p video and can be viewed on a much larger screen while the 1080p video has 1080 lines that are each 1920 pixels wide.
Mainly used 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 adequate, 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.
DVDrip: Ripping is the process of copying video, audio, and subtitle content from removable media like DVD. Through compression and other approaches such as re-encoding and others, the content will be recombined into a new multimedia file. This new multimedia file is called DVDrip.
Blueray/BRRIP/BDRIP: 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 transcoded from a pre-release, usually from a 1080p BDRip from another group.
DVDSCR: These are early DVD or BD releases of the theatrical version of a film, known as screener typically sent to movie reviewers, Academy members, and executives for review purposes. A screener normally has a message overlaid on its picture, with wording similar to: "The film you are watching is a promotional copy. If you purchased this film at a retail store, please contact 1-800-NO-COPIES to report it." or more commonly if released for awards consideration simply, "FOR YOUR CONSIDERATION." Apart from this, some movie studios release their screeners with a number of scenes of varying duration shown in black-and-white. Aside from this message, and the occasional B&W scenes, screeners are normally of only slightly lower quality than a retail DVD-Rip, due to the smaller investment in DVD mastering for the limited run. Some screener rips with the overlay message get cropped to remove the message and get released mislabeled as DVD-Rips.
HDRip: HDRip is an encoded version of any HD source, like BRRip, BDRip or HDTV, into a smaller file size. Although the original source might be in a higher resolution, scene groups often transcode the rips to 720p.
HDTS: A telesync (TS) is a bootleg recording of a film recorded in a movie theater, sometimes filmed using a professional camera on a tripod in the projection booth. The main difference between a CAM and TS copy is that the audio of a TS is captured with a direct connection to the sound source (often an FM microbroadcast provided for the hearing-impaired, or from a drive-in theater). Often, a cam is mislabeled as a telesync. HDTS is used to label a High-definition video recording.
HDTV: HDTV stands for captured source from HD television. With an HDTV source, the quality can sometimes even surpass DVD. Movies in this format are starting to grow in popularity. Some advertisements and commercial banners can be seen on some releases during playback. HDTV sources are re-encoded to multiple resolutions such as 720x404 (360p), 960×540 (540p), 1280×720 (720p), and 1920x1080 (1080p) at various file sizes for pirated releases.
WEB-DL (P2P): This is a movie or TV show downloaded via an online distribution website, such as iTunes. The quality is quite good since they are not re-encoded. The video (H.264) and audio (AC3/AAC) streams are usually extracted from the iTunes or AmazonVideo file and then remuxed into an MKV container without sacrificing quality. An advantage with these releases is that they mostly have no network logos on the screen, just like BD/DVDRips.
WebRip: This is a file losslessly ripped from a streaming service, such as Hulu, Crunchyroll, DiscoveryGO, BBC iPlayer, etc. The quality is sometimes comparable or even superior to WEB-DL, but bitrates are usually lower to save on streaming bandwidth (for example, Hulu WEBRips frequently have superior picture quality over iTunes WEB-DL, but inferior audio, AAC 2.0 vs DD 5.1). The file is often extracted using the HLS or RTMP/E protocols and remuxed from a TS, MP4, or FLV container to MKV.
