Usually download video, 4K, 1080P, Blu-ray, HDTV, HD, DVD, CAM, TS God horse, in the end what is the difference!

In the video downloaded on the Internet, you will often see several versions of BD, HDTV, TS, DVDSCR, WebDL, etc. Many users may not understand the difference between them. Today, Xiao Bian has given everyone a science magazine!


Network video file naming method:
The name of the video file on the Internet does not have a uniform standard. It is generally named after the source group and the subtitle group. However, the included elements are basically the same. It is nothing more than the naming of the names of Chinese and English names, resolutions, and bit rates.
In general, the naming is as follows:

Chinese name. English Name. Year. Source resolution. Coding method. Subtitle language. Subtitle group or suppressed group name. Format

such as:

There are many elements in the file name. This article mainly introduces it from the perspective of the video source. It helps you to understand the approximate source of the video according to the file naming to judge the quality of the resource.

1.CAM (Pistol version) - cherish life, away from the gun version

CAM is usually stolen from a movie theater using a digital video camera. Sometimes a small tripod is used, but most of the time it is impossible to use, so the camera shakes. Therefore, we see that the picture is usually dark and the characters are often distorted, and the video screen often appears tilted and shaken. Because the sound is recorded on the scene of the movie theater, laughter and other noises of the audience are often recorded. Because of these factors, the quality of images and sounds is usually very poor.

(Note: Xiao Bian does not have possession of so many goods, all the following screenshots are only corresponding to the quality version, not the corresponding movie title!)

2.TS - only slightly better than CAM

The TS and CAM standards are the same. However, it uses an external audio source (usually a headphone jack in a theater seat for a person with poor hearing). This source cannot be guaranteed to be a good source because it is subject to a lot of background noise. The TS is recorded in an empty cinema or a professional camera in the projection room, so the image quality may be better than CAM. But the ups and downs of the picture are very large. Frequently there are general TS versions and clear TS versions.

Example: Iron.Man.PROPER.TS.XviD-iLG (Iron Man TS Version)
Quality effect:


3.TC - Basic can also be ignored

TC uses a telecine machine to make direct digital copies from film. The quality of the picture is not bad, but the brightness is not enough and some of it is dark. Many times the source used by the production TC is from TS, so the sound quality is poor, but the picture quality is much better than TS. If not too careful, then the TC version is a good choice.
There is also a resource that contains: HC. The use of chaotic, can be used as a stretch of the Cam, TC, or DVDScr film source resolution to 720p, no substantive significance, the quality is still poor, gimmick.

For example: Madagascar.2005.TC.XviD.AC3.avi (Madagascar TC version)
Quality effect:

The above three kinds of film sources are sometimes used to be collectively referred to as "gunplates" because of the poor quality of pictures and sounds.

4.R5 - impatient you can see this

In order to protect intellectual property rights, the DVD Alliance divides the world into 1-6 zones depending on the geographical area. If it is inconsistent with the region code of the DVD player, it may not be able to play. Of course, online piracy is cracked, compressed into .mkv, .avi format and then shared.
The 5 zone R5 is generally mostly a Russian 5 zone version. Since the language of the blockbuster keyword blockbusters in Russia is frequently dubbed as Russian, the video with the R5+ gun version TS will be used on the network. Poor), sometimes the Russian version also has English audio, depending on the circumstances. However, the R5 version is not only poor audio quality, but in most cases the video quality is also worse than the masked version of the DVD. DVD release in R5 area is generally earlier than shielding keyword version.
Now that Blu-ray is widely available, DVDs are rare. The above situation is also applicable to Blu-ray. BluRay is also distributed worldwide, and some movies are also issued earlier than the US version.

For example: Get.Smart.R5.LINE.XViD-mVs.avi (Confused Detective R5 Edition)
Quality effect:


5.DVDScr - Worst Look at this

Preview or beta version of the DVD, an informally published version. Get it from the preview DVD. Published earlier than DVDRip, but the picture quality is slightly worse. (There are often messages that do not scroll through the screen under the black border, including copyright and anti-piracy phone numbers, which can affect viewing.). In screening the keywords at the end of the award season, the film submitted to the judges may be the source of the film (after all, the film has not been on sale, to prevent the leak to the judges can not see high-definition version), but also for those judges.

For example: Brooklyn.2015.DVDScr.XviD-ETRG (Brooklyn DVDSCR Edition)
Quality effect:


6. DVDRip - the ideal version

DVDRIP is a conversion from the final version of DVD. Quality should be the best. The DVD's video, audio, and subtitles are stripped out, compressed, or otherwise processed and then recomposed into multimedia files. In general, DVDrip consists of a video file (with the suffix avi) and a subtitle file.

An illustration: Pineapple.Express.2008.DVDRip.XviD-ARROW.avi (Pinetree Express DVDRip Edition)
Quality effect:


7.HR-HDTV - a good choice

HR-HDTV exact name is Half Resolution High Definition Television = HRHD (HR or HR-HDTV), which is everyone talking about half full HD, so HR-HDTV also called semi-HD.

After this concept was proposed, it was mainly promoted with the growth of YYTs and was well-known by everyone. In March 2007, YYeTs began producing HR-HDTV standard for movies and released a lot of experimental movie releases. It was highly praised. So after the final revision in October 2008, it was fixed by the current HR-HDTV. standard.

HR-HDTV uses HD4 video compression technology such as DivX/XviD/x264 to compress HDTV video. It then encapsulates the video and audio parts into an .avi or .mkv file, and finally creates a plug-in subtitle file. Video format.

This is supplemented by the fact that HR-HDTV has previously used HDTV sources, and Blu-ray is now widely available and easy to access. Blu-ray sources are used, and the picture quality is better. But you see the following naming, can you tell if you are using a Blu-ray source, a HDTV source, or a WEB-DL source? Therefore, the resources of everyone's film and television are a bit of a "mixed and prolific" and there is no clear source of markup.

For example: Inside.Men. Insider.2015.Korean Chinese word.HR-HDTV.1024X576.x264-HJJL
Quality effect:


Speaking off topic, what are the so-called concepts of SD, HD, Full HD, Ultra HD, and HD in China? Each video website has its own definition and there is no unified standard! Here's the 720p/1080p relationship that corresponds to these concepts:

SD - 480P - 720x480 resolution.
HD-HD-720P-1280×720 resolution. (720P)
Full HD - FHD-1080P-1920x1080 resolution. (1080P)
Super clear - UHD (Ultra HD) - 4K- 3840 * 2160 or 4096 * 2160 resolution.
HDTV - Abbreviation for HDTV, covering 720P/1080I/1080P. It is not a resolution, but a way to get resources. It is usually obtained by the user capturing the media stream in real time through the acquisition device/software.
HR-HDTV—Half HD, resolution is about 960x540, which is half of 1080P. Everyone plays an important role in setting standards and promoting universal access. (later resolution was upgraded to 1024576)

8.TVRIP - TV conversion

The so-called TVRip is a television program (digital cable TV/satellite TV capture, etc.) from TV dramas and receiving satellites. It is then captured by television cards and compressed into files. Many of the variety shows and sports programs we watch are TVRip. Some television shows are also published using TVRip. This kind of video quality mainly depends on the quality of the TV station's picture quality. The average quality of ordinary wired movies is good, and the quality of high-definition wired movies is just fine.

Now that HD digital TV is popular, it is generally HDTVRip. TVRip has rarely been seen.

9.HDTVRip

HDTVRip is a high-definition film source (HDTV recording, high-definition satellite asterisk receiver) conversion, all HDTV source video can also be labeled as HDTVRip.
Generally more common in TV dramas, especially American dramas and Korean dramas. All are recorded HD cable TVs and then repressed.

For example: Boardwalk.Empire.S05E01.720p.HDTV.x264-KILLERS (Atlantic Empire, US drama)
For example: Hail.the.Judge.1994.HDTV.x264.AAC-iHD (Nine Products Sesame White Bread, Blue Sky, Movie)
Quality effect:


10.HDRIP

HDRIP=HDTVRip ?
Personally think that now HDRip naming is a bit indiscriminate, I feel more like HDTVRip (HDTV recording), or Web-DL Rip (network online video). There is also no unified norm. How resources are named is also a matter of resource oppressors themselves! ! Therefore, the naming of resources is inevitably confusing. When you see the naming, you can't tell the source and you can't determine the quality of the image. However, HDRip is generally used instead of HDTVRip. The quality of the former is worse than that of the latter.

For example: The.Himalayas.2015.720p.HDRip.AC3.H264-CINEFOX (Himalayan)
Quality effect:


11.WEB-DL - second only to Blu-ray quality
With the development of the Internet, these sources have been very eye-catching in the past two or three years, and they have often been circulated on the Internet before Blu-ray high-definition (HD) was released. And the picture quality is very good, generally can meet the needs of the majority of HD lovers.

As the name suggests, Web-DL, Web-Download, is downloaded from the Internet. The film source is generally online video, such as the apple's iTunes, the picture quality is the best, close to the Blu-ray 720p; domestic iQIYI, Youku, Tencent, LeTV, etc., there are online paid videos, but the picture quality is too bad ! !

There are 1080P.Web-DL, 720P.Web-DL, and WEBRip (WEBRip quality is generally poor).

for example:
The Frozen Ground.2013.1080p.WEB-DL.H264-Abjex (Freeze) 1080P.Web-DL
Star.Trek.Into.Darkness.2013.720p.WEB-DL.H264-HDWinG (Star Trek: Dark Unbounded) 720P.Web-DL
Detective Chinatown 2015 720p WEB-DL x264 AAC-PuTao (Chinatown Holmes).
Quality effect:

This kind of film source is also more common in the American drama, but later than the HDTV film source, the online broadcast is always later than the TV broadcast, which also conforms to the actual situation. The picture quality is slightly better than the HDTV version.

For example: Under.the.Dome.S02E11.Black.Ice.1080p.WEB-DL.DD5.1.H.264-NTb (under the sky, US drama)
Quality effect:


12.BDRIP - The Peak of the Current Video Quality

BDRip = Blue-ray Disc Rip, ie Blu-ray HD conversion. Press with a Blu-ray disc. But most of the suppression groups use blue light
The 720P, 1080P video that is also called BDRip is wrong. It should be called BRRip, non-BDRip, and the difference between words.
720p, 1080p, Rumux, etc. all belong to the BDRip category, but for better introduction, the following separates.

For example: Awake.2007.BDRip.X264-TLF.mkv (BDRip version of life-threatening surgery)
Quality effect:


In addition, a few common resolution-based versions are briefly introduced. Many online video sites gradually differentiate their video streams in this way.


1.720P

720P is the format standard of the highest-level HD digital television set by the Society of Motion Picture and Television Engineers (SMPTE) with a resolution of 1280×720. HD resolution is mainly divided into: 1080P, 1080I, 720P (i is interlace, interlaced mean, p is Progressive, progressive meaning). 720P is a display format that achieves a resolution of 1280 x 720 under progressive scanning. It is a fusion of digital cinema imaging technology and computer technology. This is the minimum standard for high-definition video.

An illustration: On.Drakon.2015.720p.Blu-ray.Rus-HDClub.mkv (He is a dragon)
Quality effect:


Lower energy:
720p/1080p is only the resolution, so HDTV, HD-DVD, WEB-DL, and even DVD source can be compressed into 720p/1080p. Do not equate 720p/1080p with Blu-ray. Think of Blu-ray when it comes to 720p/1080p. This is a misunderstanding! Many guns will be pressed into 720P, and the definition of the movie will ultimately be determined by the video source.

2.1080P
1080P is the format standard of the highest-level HD digital television set by the Society of Motion Picture and Television Engineers (SMPTE). The effective display format is 1920×1080 and the number of pixels reaches 2.0736 million.
The high picture quality brought by 1080P brings the audio and video enjoyment of the real home theater. Because it is fully backward compatible with other high-definition formats, the versatility is very strong, ensuring that products will not be produced in the next ten years. Outdated, it has a good lead. With the constant emergence of 1080P chip sources, the advantages of 1080P products have emerged. The source of the 1080 source may be a Blu-ray Disc, and the single may also be HDTV, WEBDL, etc.

For example: Empire.State.2013.BluRay.1080p.DTS.x264-CHD (Empire, 1080P version)
Quality effect:


3, Blu-ray original
Blu-ray discs, similar to DVD discs, some movie enthusiasts will buy Blu-ray discs and then crack them. (Blue-ray discs are divided into several regions in the world, such as China's Blu-ray players, which cannot play Blu-ray discs purchased in the United States, and are copyrighted). Then publish and share on the Internet, and then suppress groups to suppress (re-encoded) into 720p/1080p and other high-definition resources. Blu-ray disc is the original source, the quality of the original, there is no secondary processing, it is very HD enthusiasts will download to watch, or collection of original Blu-ray resources. At present, Blu-ray original disks are shared as 1080p (1920×1080), and 2K and 4K are also available.

For example: Star.Trek.Into.Darkness.2013.3D.BluRay.1080p.AVC.TrueHD.7.1-TTG (Star Trek: Dark Unbounded)
Generally 40, 50G, not the average user "consumption" affordable.

Quality effect:


4, 4K - one of the future HD development

4K video can also use Blu-ray as a storage carrier with a resolution of up to 4096×2160, corresponding to higher detail, color, and picture quality. A 4K Blu-ray disc is not expected to be as high as a few hundred G. It is usually only a few tens of G.

For example: Spider.Man.3.2007.4K.Mastered.Blu-ray.1080p.AVC.DTS-HD.MA.5.1.-BLUEBIRD
(4K is not cut off, but if you cut the picture quality, it will be discounted. Imagine it is clearer than the above 1080P...)

High resolution does not mean large volume, which is the most misunderstood for everyone. The size of the volume is not proportional to the resolution but directly proportional to the code rate.
With 4K blue light suppressed 720p/1080p, naming will generally include: 4K, Remastered words, or both.

For example: Spider-Man.Trilogy.2002-2007.4K.Remastered.BluRay.1080p.x264.DTS-HD.MA.5.1-HDWinG

There may be doubts about the significance of 4K's film source conversion to 720p. My personal understanding here is that we say that the 4K image quality is good not only because of the high resolution, but also the improvement of many elements such as details, colors, etc. It is impossible to improve the image quality simply by increasing the resolution, such as a few straight lines. Kb's picture, you can use the image processing software, stretched into 4K (4096 × 2160) resolution, but obviously, after stretching, it will appear blurred.

Similarly, the same resolution does not mean the same picture quality. For example, if the iPhone 800 and the millet 800 are photos, can the resolution be the same? Therefore, the relationship between the definition of the image quality and the resolution can only be established under certain conditions.

Say another sentence, at present, many online video sites already have 4K picture quality, but many of them are 1080P Blu-ray discs stretched into 4K resolution.
