Cheat sheet for decoding video file names
Have you ever wonder what are different letters / numbers mean in the titles of video files?
I have taken all the information from Google and I hope this cheat sheet will be useful for somebody.
CAMRip (CAM, deriving from camera)
Sometimes, it is mistakenly labeled as Screen (SCR). Video and audio are recorded on camera in a movie theatre. At times the shaken image can be taken at an angle to the screen, and in some movies could be seen heads of moviegoers, etc. The sound quality might be different such as laughing audience. Usually, it is the worst and the very first quality of movie, which could be found after the official release.
Ideally, it is being recorded from the screen with a professional (digital) camera mounted on a tripod in an empty movie theatre or in the operator's cab. The video quality is much better than in CAMRip. Sound is recorded directly from the projector or other specific output, such as the headphone jack in the chair. Thus, the sound is very nice and smooth in stereo.
Telecine (TC, “Roll")
A copy is taken from the movie using the special equipment (film scanner), or it is recorded from a special projector with the outputs for audio and video. The quality depends on the used equipment (the quality varies from good to indistinguishable from the original DVD), the sound is excellent. Sometimes there are problems with the natural colors ("yellowness" of picture).
Super Telesync (Super TS, Super-TS, “digitization")
The TS (rarely TC) is run through the computer, the film is brightened, aligned, and there are removed extraneous noises of image and sound, etc. The quality is often good, but it depends on the creator.
Rip is from the original DVD, it is often compressed in MPEG4 to reduce the size of the movie. Basically, there are sizes of 650-700 MB DVDRip and 1.3-1.5 GB. Quality is very good, but it depends on the skill of the creator (or "ripper"). Sometimes, the best quality versions are marked as SuperDVD, HQ DVD.
This copy (uncompressed) is from the original DVD. Size: 4-4.5 GB.
This copy (uncompressed) is from dual-layer original DVD. Size: 7-9 GB.
DVD-Rip is from CD, distributed within the CIS countries (and such discs are released earlier than in other countries) with the original (English) sound track, taken from other sources.
As an option - Telecine (TC, “Roll").
DVD-Screener (DVDScr, DVDScreener) (SCR)
A promotional copy is from DVD (disk is for film critics, promotional or beta version). Quality is as DVDRip, but the picture is usually marked by the water signs, warning signs and black and white inserts ("disappearing color").
SCREENER (SCR) or VHS-SCREENER (VHSScr)
This is the same thing as DVDScr, but only it is from a video cassette. A promotional copy VHS (tape is for the film critics, promotional or beta version). The picture quality is comparable to a very good VHS, but the picture is usually marked by the water signs, warning signs and black and white inserts ("disappearing color"). Sound is good, usually stereo or Dolby Surround.
Pure Digital Television Rip - rip is from the pure digital television. The marking shows that the encoding was not converted from the analog signal to the digital. Under general marking PDTV-Rip may be hiding SAT-Rip, DVB-RIP, and IPTV-RIP. The source could be a satellite channel (DVB-S), non-coded terrestrial digital broadcasting DVB-T, sometimes IP-TV and another channel for digital broadcasting, which does not use special methods to prevent direct recording of the digital stream. Most often, there is a channel logotype.
Material is recorded from a television signal, usually a cable (but there are also some from a simple antenna). Almost all TV series primarily are transmitted in this format or SATRip. The quality depends on the hardware, software and the ripper skills.
The raw audio-video stream that is taken directly from a digital television.
It is similarly to TVRip. The material is recorded from a satellite video (usually a digital MPEG2 video). The quality depends on the provider of the channel and the quality rip. Usually, this Rip only is slightly inferior to DVDRip (although there are some exceptions). Most often there is a channel logotype.
It is the same as SAT-Rip (SATRip).
It is similarly to SATRip. Material is recorded from a digital IP-TV (a digital MPEG2 or MPEG4 video). Usually, this rip is only slightly inferior to DVDRip. Most often, there is a channel logotype. It appeared recently.
WEB-DL, and WEB-DL 720p
Rips received from the broadcasts over the Internet iTunes Store. The main feature is the high quality (along with BDRips), there are no logos of TV channels.
iTunes Digital Copy
Video received from the online Apple Store by the code number that is on the package license DVD or BD, or it located directly on the disk.
DVB-Rip (DVBRip, DVB-T Rip)
It is similarly to SATRip. Material is recorded from the digital terrestrial television (usually a digital MPEG2 video, and occasionally MPEG4). The quality depends on the provider of the channel and the rip itself. Usually, this Rip is only slightly inferior to DVDRip (although there are some exceptions). Most often, there is a channel logotype.
This Rip is from the HDTV movie (1920x1080, 1280x720), which is often done by ordinary resolution rip (sometimes, it is with the original resolution). The quality is often better than DVDRip. Under general name HDTV-Rip are met the rips with BD-Rip, HDDVD-Rip, digital satellite and cable operators that broadcast in HDTV. Description includes: 720p, 1080p, 1080i, 1280p (see below).
BD-Rip (BDRip, BRRip, BR-Rip)
Rip is from a Blu-Ray DVD disc (25 GB per layer). It refers to an HDTV. These BDRip films have the better quality than DVDRip. The file size is from 2 to 9.5 GB. The size of the image is indicated as well. For example, BDRip.720p BDRip.1080p. Sometimes, there are rips from the DVD with the enlarged picture and an incorrect marking of BDRip.
HD-DVD-Rip (HDDVDRip, HDDVD-Rip, HDDVD)
Rip is from HD DVD disc (15 GB per layer). It refers to an HDTV. In connection with the actual loss of HD-DVD in format war to Blu-Ray VS HD-DVD, the number of these rips will be marginal.
Rebuilt streams of the original HDDVD without the menu in container, as a rule TS or MKV.
Video is identical to the original one. No loss in quality.
Rebuilt streams of the original BlyRay disc without menus in the container, as a rule TS or MKV.
Video is identical to the original one. No loss in quality.
It is similarly to DVDRip. This version is made from Laserdisc. It is quite rare, mostly old movies.
Source material is a cassette of format VHS, it is usually pretty average quality.
It is digitization of a cassette of high-definition. The video quality is high enough. It may contain noise and blurred images.
AVC (Advanced Video Coding)
Licensed video compression standard (H.264 or MPEG-4 Part 10), designed to achieve the high compression of video stream while keeping the high quality of video.
720p, 1080p, 1080i, 1280p, etc. – These marking are found in HDTV movies and rips.
The digit is picture resolution in the vertical at a ratio of 16:9. For example, 720p - 1280x720.
i (interlaced scan) is interlacing, the image is formed from two half-frames (as in a normal TV). This decreases the stream (hence file size), but the motion shows the so-called "comb effect" on the border of colors. Rate is 50 or 60 half-frames per second.
p (progressive scan) is progressive scan, the frame is transmitted and fully formed, and the picture is not distorted in the movement. Lack of progressive, stream is increased in two times in comparison to interlaced. As a result, it has a big file size or a small frame rate.
Display Aspect Ratio
It is released in full screen, 3:4 video resolutions. Often Fullscreen is made from Widescreen version using Pan and Scan (PS), cutting off part of the frame on each side.
It is one of the original widescreen video recording options on the DVD (the other - Letterbox), anamorphic (image, typically 16:9 stretched to 4:3 full frame – as a result, the quality is better).
It is one of the original widescreen video recording options on the DVD (the other - Widescreen (WS)), an image, usually 16:9 not stretched on the whole frame, and there are left the black stripes above and below.
Pan and Scan (PS)
It is the method of converting widescreen (WS) video in full screen fullscreen (FS). In this part the frame is cut on the right and left.
They are small logos of TV-channel or releaser.
Director's Cut (DC)
Directors Cut is a special edition of the film, representing the film from the perspective of the stage director, but not redrafted in accordance with the requirements of customers, distributors, studios, critics, etc.
This is so-called "beta version" of the film. Particularly, it is interesting for the fans of movies. Usually, it is released in VCD format much earlier before the show in theaters around the world. Because this is a preliminary version of the film, the quality of the material may be excellent, and very low. Frequently, some scenes and computer special effects may not be available. However, in the Workprint can also be scenes that will be cut out of the final version. You can recognize these versions by a timer at the top or bottom of the screen (it is needed for later editing of the final version).
The film was shown to a limited number of cinemas. Usually, no more than 250-500.
Special Edition (SE)
It is a special version of the film. A striking example is the restored version of "Star Wars" with the addition of the material 70s of computer graphics, animation, 3D-models.
Straight To Video (STV)
The film was released directly to DVD / cassette bypassing movie theaters. Quality is DVDrip or VHSrip.
The second release of the same film by another release group (usually, it is stolen from the first one).
Re-release of the film (sometimes by another group) due to poor quality of the previous one.
The release that is converted to another format or re-coded.
New rip of the movie.
The original sound is removed from the film. For example, the sound track of Russian cinema is taken and overlaid on the American release.
It is the same as Dubbed; only the sound was recorded by a microphone at a cinema.
It is the same as Dubbed, only in this case the sound was taken from the "chair" or "projection» (Line).
D - duplicated (dubbing)
L1 - single voice amateur translation
L2 - double voice amateur translation
L - multi voice amateur translation
O - original
P1 - professional single voice translation
P2 - professional double voice translation
P - professional multi voice translation
It should be noted that the letter P in the name of the film can also denote a professional double voice translation, as well as L – amateur double voice, as many release groups do not divide into double voice and multi voice translations.
AVO - (Author Voice Over)
SVO (1VO) - (Single Voice Over)
DVO (2VO) - (Double Voice Over)
MVO - (Multi Voice Over)
DUB - (Dublicated)
SUB - (Subtitle)
Dubbed translation (dubbing) is when the film actors speak in a language you understand, and when absolutely you cannot hear the original language with all other sounds and lipsync that is the viewer has the impression that the actor talks in their native language.
Full dubbing of the film is technically complex process and it is considered as a top in the movie voice acting. It is done by professionals in the film studios. In order to duplicate the movie all the recorded sounds and voices must be separated to replace the voices.
Multi voice over (can be professional or amateur), this is when the original language of film is muted (simultaneously, muted other sounds) and over the voices of several actors (professional) or actors (amateur) are overlaid voices, but the original soundtrack is still slightly audible.
Double voice over, it is when the film is voiced by a man and a woman.
Single voice over translation, it is when one person voices all the actors (usually male). Such translations are particularly familiar to all lovers of movies on video 80-90s.They are samples of the translators’ voices.
Simultaneous translation is a translation of speaker’s speech with a lag of 2-3 seconds.
The film has subtitles.
Subtitles embedded into the video stream.
Subtitles are coming in a separate file / stream, and rendered by the player.
