We can see it in the movie titles of many movie download websites, such as "Assassination of Hitler BD Edition" and "The Prince and the showgirl TS Edition". What do these English abbreviations mean? What image quality does it represent? Let's sort out the specific meaning of each version: 1, CAM (gun version) CAM is usually pirated from cinemas with digital cameras. Sometimes a small tripod is used, but most of the time it is not available, so the camera will shake. So we see that the picture is usually dark, the characters are often distorted, and the subtitles below are often tilted. Because the sound is recorded from the camera's own microphone, the audience's laughter and other sounds are often recorded. Due to these factors, the image and sound quality is usually poor. 2.TS (quasi-gun version) TS is the abbreviation of TELESYNC. The standards of TS and CAM are the same. But it uses an external sound source (usually the earphone hole for the hard-of-hearing people in the cinema seat). This sound source cannot be guaranteed to be a good sound source because it is interfered by many background noises. TS was recorded with a professional camera in an empty cinema or projection room, so the picture quality may be better than CAM. But the picture fluctuates greatly. There are general TS version and revised TS version 3, and TC (film version) TC is the abbreviation of TELECINE. TC uses telecine machines to make digital copies directly from film. The picture quality is not bad, but the brightness is not enough, which is a bit dim. Many times, the sound source used for TC comes from TS, so the sound quality is very poor, but the picture quality is far better than TS. If it is not too particular, TC version is still a good choice. 4.DVDSCR (pre-sale version) SCR is the abbreviation of SCREENER. Preview or beta DVD, unofficial version. The video format obtained from preview DVD is compressed with high quality by mpeg-4 technology. It can be released earlier than DVDRip, but the picture quality is slightly worse. There are often some information that does not scroll at the bottom of the black screen, including copyright and anti-piracy phone numbers, which will affect viewing. Without strict division, its picture quality should be similar to that of TC version. 5.R5 (Russian 5th Edition) The DVD of Russian 5th Edition needs to find English tracks because it is dubbed in Russian. Version R5 is a synthetic version (DVD video of Russian Zone 5+English tracks obtained through other channels). The sound quality of R5 version is generally good, and the audio part has both good and bad effects due to the different sources of audio tracks. 6.HD RIP (high definition version) HDTVRip is the abbreviation of HDTVRIP (high definition television resource compression). It is a video format, which compresses HDTV video images with high quality by using MPEG4 4 compression technology (such as Divx/XVI/X264), and then encapsulates the video and audio parts into one. Avi is still. Mkv file, and finally add plug-in subtitle file. The picture definition is higher. 7.BD (Blu-ray Edition) BD is the abbreviation of Blue Disk, which means "Blu-ray Disc" when translated into Chinese. It is a video and audio transcribed from a Blu-ray disc, and the picture definition is very high. 8. The full English name of DVD, HDVD, DVD 5 and DVD 9 is Digital Video Disk, that is, digital video disc or digital video disc, which uses MPEG2 compression technology to store images. 9.HDVD (compact disc or economy DVD) HDVD is usually called compact disc or economy DVD. Media are usually DVD-5 (with a capacity of 4.7G) and DVD-9 (with a capacity of 8.5G), and are encoded by MPEG- 1 or MPEG-2. Due to the low bit stream, each disc can accommodate up to 7 hours of video programs, and the quality level is slightly higher than or equal to VCD. Watching soap operas is the most economical. 10, VHSRip VHSRip is transformed from retail VHS video tapes, which is mainly used for releasing skating/sports content. 1 1, TV-transformed TVRip TV series (preferably intercepted from digital cable TV/satellite TV), or receive pre-broadcast programs transmitted by satellite to the TV network a few days in advance (excluding encryption but sometimes snowflakes). Some programs, such as WWF RAW IS WAR, contain redundant parts; TVRip includes "dark matching" and camera/commentary test. PDTV is captured from PCI digital TV card, which usually has the best effect; Cracking organizations tend to use SVCD to publish. VCD/SVCD/DivX/XviD rip is also used to publish TVRip. 12, work print(WP)work pritn(WP WP WP) is converted from an unfinished movie copy, and shots and music may be lost. The quality may vary from the best to the worst. Some WP may be far from the final version. Men in black WP lost all aliens and replaced them with actors. Others include extra shots (Jay and silent Bob). WPs can be used as an additional collection after the final version with good quality. 13 and DivX Re-Enc DivXRe-Enc are smaller files encoded by DivX released by the original VCD. It can usually be found on file sharing networks. They are usually named in the form of movies. Name. Group (1of2). Common publishing organizations are SMR and TND. These versions are usually not worth downloading, unless you don't understand movies and just want the 200MB version. Generally should be avoided. 14, Watermark Many films of Asian Silver /PDVD (see below) bear the producer's mark. Usually letters, initials or icons, located in the corner of the screen. The most famous ones are "Z", "A" and "Globe". 15, Asian silver /PDVD Asian silver /PDVD is a pirated film released in Asia, which is usually purchased by some distribution agencies as their own distribution. In many countries, silver is cheap and easy to find. It's easy to release Silvers, so a lot of them are released now, mainly some small institutions; These organizations usually release several versions and then disappear. PDVD is the same as Silver, but it is on DVD. PDVD usually has external subtitles, which are better than silver. PDVD is converted like ordinary DVD, but usually the logo of the scene label release file is released in VCD format. 16, according to the release rules properly, the organization that released Telesync (TS) first won the competition. However, if the released version is of poor quality and another organization has another TS version (or the same movie source with better quality), the tag itself is added to the catalog to avoid duplication. Appropriateness is the most subjective sign, and many people will argue whether appropriateness is better than the original. Many publishing houses only issue genuine copies because they failed in the publishing competition. The appropriate reason for publishing should always be included in the NFO file. 17, SUBBED is the release of VCD. SUBBED usually means that subtitles are pressed into movies. Usually Malay/Chinese/Thai, sometimes there are two languages. They may occupy a large part of the screen. SVCD supports external subtitles, so DVDRip is published with external subtitles. This information can be found in the NFO file. 18, Untitled When a movie has been released with subtitles, an untitled version without subtitles may also be released. 19, limited film means that the film is only shown in a limited number of theaters, usually within 250. Usually, the distribution of smaller films (such as art films) is limited. 20. There are several reasons for internal release. There are many traditional DVD organizations. Inside. Releasing the version will not cause confusion. At the same time, low-quality publications will be marked as internal, which will not reduce the reputation of publishing institutions, or because of the number of publications already published. Internal publications can be obtained from the member websites of the organization normally, but they cannot be exchanged to other websites without the requirements of other webmasters. Some internal releases still flow to IRC/ newsgroups, which usually depends on the movie and its popularity. Earlier this year, people called CENTROPY an internal company. This means that the publishing organization only publishes to its members and webmasters. This is different from its usual meaning. 2 1, STV STV means that the movie was released before it was released in the cinema, so many websites don't allow STV. 22 \ The aspect ratio label *ws* indicates widescreen and *FS* indicates full screen. 23.RECODE RECODE is a previously released version, which is usually filtered by TMPGenc code to remove subtitles and correct colors. Although they look better, they are usually not considered as a good behavior, because publishing institutions should find their own sources. 24. Repackaging If the publishing organization releases a bad version, they will release repackaging to solve these problems. 25.NUKED For various reasons, a version may be deleted by Nuked. Some websites will publish NUKE because they violate their rules (such as not allowing the release of TS version). But if there is a big problem with the released version (for example, there is no sound for 20 minutes, and CD2 is the wrong movie or game), then all websites will publish NUKE. People who exchange nuclear weapons versions on these websites will lose their credibility. However, the release of NUKED can still be spread through P2P/USENET, so we always have to find out why it was Nuked first, just in case. If the publishing agency finds that there is something wrong with its own publishing, it can ask NUKE. 1080P Usually, the picture resolution of 1080P is 1920× 1080, which is also commonly known as HDTV. The effective display format is 1920× 1080, and the number of pixels reaches 2,073,600. The number 1080 indicates that there are 1080 scanning lines in the vertical direction, and the letter p indicates progressive scanning. The frame rate is usually 30 frames per second (FPS), which can be marked after p, such as 1080p30. Common frame rates are 24, 25 and 30. It is not necessary for HDMI to have the output of 1080p, but the video source must be able to support1920x 1080p to be the real output of1080p. 1080P refers to the program that can display 1920* 1080, but the TV itself does not have the physical resolution of 1920* 1080, only1920 */kloc. The physical resolution of the 32-inch LCD TV is 1366*768, but the manual may indicate 1080P, that is, the image processing of 1920* 1080 is shown as 1366*768. This 1080P is the highest resolution or display resolution, which only shows that this TV can receive the signal of 1920* 1080, but it is not 1920* 1080 when it is displayed. As for the format of 1080P, most people often use another term "full HD" (which can be translated as "full HD" in Chinese), but 1080P is not full HD. What is Full HD? Full HD is a flat panel TV that can fully display 1920* 1080 pixels or the physical resolution reaches 1920* 1080. If you watch HDTV programs, you need to use full HDTV to achieve the best results. It should be noted that full HD and 1080P advertised by many manufacturers before are not the same concept. 1080P brings high picture quality, which brings consumers real audio-visual enjoyment in home theater. Because it is fully compatible with other high-definition formats, it is very versatile, ensuring that the products will not be outdated in the next decade and have a good lead. With the continuous emergence of 1080P film sources, the advantages of 1080P products have emerged. 720P 720P is the format standard of high-level high-definition digital TV set formulated by American Society of Motion Picture and Television Engineers (SMPTE), and its effective display format is: 1280×720. SMPTE divides the scanning lines of digital HD signals into 1080P, 1080I and 720P (SMPTE). 720P is a display format with a resolution of 1280×720 under progressive scanning. It is the fusion of digital film imaging technology and computer technology. The development of digital TV from 1080i to 720p to 1080p 1080i and 720p is an internationally recognized standard for digital HDTV. The original NTSC countries adopted the format of 1080i/60Hz, which is the same as the field frequency of NTSC analog TV. While some countries adopting PAL system, such as Europe and China, adopt 1080i/50Hz mode, and the field frequency is the same as PAL analog TV. As for 720p, IT has become an optional standard due to the deeper penetration of IT vendors into the TV industry. At present, it has begun to expand its territory in the field of high-definition TV players based on optical discs. Taking the Japanese digital TV standard as an example, according to the different display formats, * * is divided into the following five specifications: D 1 480i format, which is the same as NTSC analog TV, with 525 vertical scanning lines, 483 visible vertical scanning lines, 4: 3 or 16: 9, interlaced /60Hz, and line frequency/KLOC-0. D2 is in 480P format, which is the same as that of progressive DVD. There are 525 vertical scanning lines, showing 480 vertical scanning lines, 4: 3 or 16: 9, resolution of 640×480, line by line /60Hz, line frequency of 3 1.5KHz. D3 is in the format of 1080i, which is a standard digital TV display mode. Vertical scanning lines Visible vertical scanning lines1080,65438d4 are standard digital TV display modes, with 720p format, 750 vertical scanning lines and 720 visible vertical scanning lines, 16: 9, resolution 1280×720, line by line /60Hz and line frequency of 45KHz. D5 is in the format of 1080p, which is a standard digital TV display mode. The vertical scanning line is 1 125, and the visible vertical scanning line is 1080, 16: 9, and the resolution is1920×/. There is also 576i, which is the standard PAL TV display mode, with 625 vertical scanning lines and 576 visible vertical scanning lines, 4: 3 or 16: 9, interlaced /50Hz, and recorded as 576i or 625i. D3 1080i is the basic format of HDTV, but it is also compatible with 720p format. As an advanced professional mode, D5 standard 1080p is widely used in TV stations and film production. The 1080i and 720p TV signals sent by the TV station are converted and broadcast by the 1080p signal source. It can be seen that 1080p is an actual standard, but 1080p is not a standard currently used in the civil field. 1080p not only has a field frequency of 60Hz, but actually three field frequency specifications of 24Hz, 25Hz and 30Hz are the most widely used. We know that movies play movies at a speed of 24 per second. Digital images shot in 1080p/24Hz mode can be transmitted to digital film projectors such as DLP/D-ILA without loss, and played in film format. 1080p/24Hz is the format of the movie. If the HD content is shot in the format of 1080p/25Hz, each frame of the complete 1080p image can be easily split into two interlaced 1080i images. In this way, the format of 1080p/25Hz becomes an image of 1080i/50Hz, which is convenient to be applied to digital HDTV in Europe and China. Similarly, 1080p/30Hz can be easily converted into an image of 1080i/60Hz after shooting, which is convenient for use in the original NTSC analog TV countries such as ATS in the United States and ISDB in Japan. The official release of various movie CDs. VCD, VCD videos can only be encoded by old-fashioned video such as MPEG 1, and the resolution can only reach above 300* 100, with poor definition and almost eliminated. MPEG2-2 encoded DVD is very large, and a 120-minute movie needs 4-5G. A 120-minute movie is only 700- 1400M after being recoded by Xvid or DivX, and its definition is the same as that of MPEG2. DVD belongs to SD, SD. HDDVD, a new generation of optical disk storage, a HDDVD disk can reach the capacity of 15-50G, which can provide greater resolution and code rate. Due to losing to Blu-ray in strength, research and development has stopped now. It belongs to HD. BD, BLU-RAY DISK (BD for short) is a new generation of optical disc storage. Ordinary Blu-ray discs can reach a capacity of more than 20G, and the setting reaches an astonishing 100G, which can store clearer movies. It belongs to HD.
