Gossip-differences in movie resource formats

I saw Avatar 3D before, and now I download the resources of the online avatar dvdscr version. Let's take a look at the differences between these formats:

Cam (Gun version )-
Cam usually uses digital cameras to steal videos from cinemas. That is, the so-called "movie version" can sometimes be used to steal videos in cinemas, but most of the time it is impossible, unless the Administrator is your relative or you have killed the administrator, for this reason, the camera is often jitters. In addition, because the sound is recorded from the microphone that comes with the camera, it is often recorded to the laughter and other sounds of the audience, especially comedy films. Because of these factors, image and sound quality are usually poor. We usually say that the gun version is the cam version.
Telesync (TS )-
Ts is superior to Cam in that it uses an external sound source during video stealing (generally the in-ear hole for persons with poor hearing in the cinema seat ), however, this does not mean that telesysnc (TS) is much better than Cam. External audio sources are often disturbed by the background environment, which sounds very noisy. In many cases, ts is recorded in an empty cinema or recorded in the projection room using a professional camera. Therefore, the image quality is generally better than cam. However, the quality may fluctuate greatly. You 'd better check the sample before downloading it. A large proportion of TS is marked from Cam errors.
Telecine (TC )-
Telecine (TC) uses a television and film machine to directly copy digital copies from the film. Its image and sound quality should have been good. However, TC is rare because of the high cost and equipment used. The correct aspect ratio is usually used, but sometimes there are 4-3 TC. Jurassic Park III is a good example. TC and timecode should not be confused. Time code is a counter visible on the screen.
Screener (SCR )-
SCR is a transcription of a promotional video (VHS) that is sent to a video rental store or another place before the launch of a movie. Generally, it uses a 4-3 full screen format, 1.85: 1-width screen format is rare. The biggest drawback of SCR is "ticker" (the Anti-Piracy phone number and copyright statement that are continuously rolled under the screen ). At the same time, if the image contains any version serial number or any mark that can trace the source, it must be shielded. These marks sometimes only appear for a few seconds, but sometimes they will unfortunately run through the whole movie, sometimes even very big !! If SCR is a mother-band transcription, the image quality will be good, but if it is another copy transcription, it will not be sure, and SCR has a high requirement on the transcription equipment, generally, it is converted into the VCD format (and also into the SVCD format, which seems to be of better quality), but in general it cannot guarantee superior quality!
DVD-SCREENER (Dvdscr )-
Dvdscr is also a transcription of promotional products, but unlike SCR, It is a transcription of the DVD used for promotional purposes, and is usually in the 1.85: 1 wide screen format, there are also "ticker" and blocking. If you are a master at transcription, dvdscr is of high quality and is usually transcribed into SVCD or DivX/Xvid format.
DVDRip -
It is converted from the final retail version of the DVD, and the quality is very high... it is usually converted into SVCD or DivX/Xvid format.
Vhsrip -
Vhsrip is transformed from the retail version of VHS Video Tape,
DivX re-ENC -
Divxre-ENC is a small file encoded with DivX released from the original VCD. They are usually named in the form of film. Name. Group (1of2. Common publishing organizations include SMR and TND. These versions are generally not worth downloading, unless you are not sure about a movie, you only want a MB version.
Subbed -
Subbed usually indicates that subtitles are pressed into a movie. They are usually Malay/Chinese/Thai, and sometimes have two languages. They may occupy a large part of the screen.
Unsubbed -
The unsubbed version indicates that subtitles are not pressed into a movie. You need to use vobsub and other external subtitle tools to display subtitles.
Others:
Proper -Full Version
Unarate -Not deleted
R_ratee -Strikethrough
WS -Wide Screen
FS -Full Screen
With extras -Film highlights
3. Identify common formats of video resources.
1. DVDRip (DivX)
The so-called DVDRip is to use DivX compression technology to compress high-quality video images of a DVD disk, and use MP3 or AC3 to compress audio, then, combine the video and audio into an AVI (AVI is audio video interleaved, audio and video are staggered), and then add the plug-in subtitle file to form the audio and video playing format. It is usually several hundred megabytes in size, which is one of the scores of the DVD volume. Note: After the DVD is converted to DVDrip, some DVD features such as menu navigation, audio track selection, and segment selection will be lost. However, compared with its advantages and ease of collection, these losses are negligible.
2. Rmvb
This format is extended by the RM video format upgrade. VB (VBR) is the abbreviation of varable bit rate (bit rate that can be changed). It breaks the Average Compression Sampling Method in RM format and ensures the average compression ratio, the rational use of Bit Rate resources enables rmvb to minimize the film size at the cost of a small part of the film quality, and ultimately perfect close to the quality of the DVD.
Compared with DVDRip, the advantages of rmvb are self-evident. First, while ensuring the overall audio-visual effect of the video, rmvb is only about MB to about MB (calculated based on a 90-minute standard movie ), DVDRip requires 700mb or more. In addition, it has the advantages of built-in subtitles, no plug-in support, and low system share for playing. These advantages make it a mainstream format for online movies.
3. MKV
Many of my friends think it is a disruption to the mainstream media formats of DVDRip in the future. It is actually a new multimedia Encapsulation Format, also known as multimedia container ). It is different from DivX, Xvid, and other video encoding formats, as well as MP3, Ogg, and other audio encoding formats. MKV only provides a "Combination" and "encapsulation" format for these audios and videos. In other words, it is a container format. Common AVI, VOD, mpge, and RM formats also belong to this type. However, they are either outdated or not open enough, which leads to the birth of the MKV multimedia Encapsulation Format.
The biggest feature of MKV is that it can accommodate a variety of video, audio, and Subtitle streams of different types of encoding, and even stream media such as RealMedia and QuickTime, which are very closed, it can be said that it was a major disruption to the traditional media format, and almost changed to a media container capable of 10 thousand.
You do not need a dedicated player for playing MKV. Any DirectShow-based player can play it, such as a common media player classic, bsplayer, zoomplayer player, or even a Windows Media Player, you only need to install the corresponding matroska decoder splitter plug-in. We recommend that you download the hapyshow decoder integration software.
(1) Avi
This is also known as the DVD version. A movie is MB ~ About Gbps, not as good as HD. However, it is currently the best quality film that is widely used. There are various options for DVD, basically 2 ~ after the latest movies are released ~ In about three months, there will be a network in AVI format.
(2) ASF
ASF is the abbreviation of Advanced Streaming Format. The meaning of this format should be seen from the literal (Advanced stream format. To put it bluntly, ASF is a File compression format developed by Microsoft to compete with the current Real Player. It can directly watch video programs on the Internet! Because it uses MPEG4 Compression Algorithm , So the compression ratio and image quality are very good. Because ASF is a video stream format that can be instantly watched on the Internet, its image quality is not surprisingly inferior to that of VCD, but it is better than the ram format in the same video "stream" format. However, if you choose the best quality to compress files without considering the spread on the Internet, it is not surprising that the generated video file is better than that of VCD (mpeg1, the original development intention of ASF is lost. It is better to simply use N Avi or DivX. However, Microsoft's "Sub-division" has its unique advantages. The most obvious difference is that no one can compete for the support of various types of software.
(3) MPEG
MPEG is the abbreviation of Motion Picture Experts Group, which includes MPEG-1, MPEG-2 and MPEG-4 (note, no MPEG-3, the familiar MP3 is just MPEG layeur 3 ). MPEG-1 is believed to be the most contact, because it is widely used in the production of VCD and some video clip download network applications, it can be said that 99% of the VCD are compressed with mpeg1 format, (note that vcd2.0 does not indicate that VCD is compressed with a MPEG-2) using the MPEG-1 compression algorithm, you can compress a 120-minute-long movie (without video files) to about 1.2 GB. MPEG-2 is applied in the production of DVD (compression), at the same time in some HDTV (high definition television broadcasting) and some demanding video editing, processing also has a considerable application area. Compress a 120-minute-long movie (without video files) to 4 to 8 GB size (of course, its image quality and other performance indicators MPEG-1 is not comparable ). MPEG-4 is a new compression algorithm that uses the ASF format to compress a 120-minute-long movie (without video files) to a video stream of about 300 MB, available for viewing on the Internet. Other DivX formats can be compressed to about 600 m, but their image quality is much better than ASF.
(4) QuickTime (Mov)
QuickTime (mov) is a video format created by Apple, which exists only on Apple's Mac for a long time. It was later developed to support the Windows platform, but in all fairness, it is an excellent video encoding format, whether it is played locally or transmitted online as a video stream format.
(5) Real Video (RA, Ram)
From the very beginning, the real video (RA, Ram) format is positioned in the video stream application. It can be said that it is the pioneer of video stream technology. It can enable uninterrupted video playback when using a 56 K modem to dial up the Internet. Of course, its image quality is not flattering to MPEG2 and DivX. After all, it takes a great deal of bandwidth to realize uninterrupted video transmission on the Internet. In this regard, ASF is a strong competitor!
High-Definition audio and video files that are popular on the Internet are classified into three categories: DVDRip, rmvb, and MKV. They use high-definition quality and sound effects that are close to original quality, it allows many people to enjoy high-quality movies through the Internet.
