Everyone is like to watch movies. Therefore most of the people download movies from internet. The most reliable method is download films by torrents. When we download movies there are some words like CAM, DVDRip, TS, SRS etc… But do you know what are the meaning of those words?  If don’t take a look at the following before download the next film.

There is a meaning for each every abbreviations.  They are the formats of the movies.  Lets get some details of these words.

CAM
Commonly this format is known as camera copy. Most of times someone brings a camera to a theater and record in there from the camera. some times the screen waves also the angle of the movie changes where the person records. Hard to read letters in the screen. Use microphone of the camera to record audio. Rarely there are some CAM copies with good quality. But most of the time CAM format is very bad quality. We can get CAM copies after a week when the movie release.


TELESYNC (TS)
Most of things in TELESYNC and CAM formats are same. The only difference is the audio of the movie gets in a separate place via cable. There are places in the theater built for less hearing  people to hear the sound of the movie with headphone.  Using that jack  gets audio to the camera. Therefore TELESYNC format audio will be high quality but video is same as CAM format.

TELECINE
This format is hard to find. The reels of the movie in the theater converts to digital to make this format. It is hard to find these equipment to make this format, so it is rare to find these type of copies. But the quality of this format is good.

SCREENER (SCR)
When a movie get released there is a preview which made of VHS to send different places. it is in a VHS tape. That tape converts into digital to make this format. If the VHS tape is new the format will be clear. But there is some sentences and announcements during the movie about copyright laws.

DVD SCREENER (DVDscr)
This format is same as SCR. The only difference in this format is it is copied from a DVD . Other things are same as SCR.

DVDRip
The most famous format is this DVDRip format. It is made from a legal DVD after screening in theaters. It’s audio and the video is in good quality. The main disadvantage of this is we have to wait more time to release a DVD of the movie.

VHSRip
This format same as DVDRip. The only difference is it is made from VHS not from a DVD.

BDRip
This format is made from a blue-ray disc. It has more pixels like 1080p or 720p. It is ahead from DVDRip format.

TVRip
TVRip format made from a TV which broadcasting the film. It has good quality but having dots in the screen.

HDRip
This format makes from a HD TV. It’s quality is better than TVRip and much less quality than BDRip.

DivX Re-Enc
When is the movie in a DVD or a VCD disk it converts into small size DivX file. Most of the time the movie which made from this format will be size of 350mb, 200mb.

DivX/XviD
This copy is known as Divx or XviD. it is not like other formats. There are two codec which are known as low motion and high motion. Most of time use only high motion codes.

M2TS 
M2TS is a filename extension used for the Blu-ray Disc Audio-Video (BDAV) MPEG-2 Transport Stream (M2TS) container file format. It is used for multiplexing audio, video and other streams. It is based on the MPEG-2 transport stream container. This container format is commonly used for high definition video on Blu-ray Disc and AVCHD. It is informally called M2TS. The BDAV container format (.m2ts), supported video compression formats H.262/MPEG-2 Part 2, H.264/MPEG-4 AVC or SMPTE VC-1 & audio compression formats such as Dolby Digital, DTS or uncompressed Linear PCM. Optionally supported audio formats are Dolby Digital Plus, DTS-HD High Resolution Audio and Dolby TrueHD.

Mkv
The Matroska Multimedia Container is an open standard free container format, a file format that can hold an unlimited number of video, audio, picture, or subtitle tracks in one file. (It was known as MKV) Matroska file extensions are .MKV for video (with subtitles and audio), .MK3D for stereoscopic video, .MKA for audio-only files, and .MKS for subtitles only. The name "Matroska" is derived from the Russian word Matryoshka, which means nesting doll. Matroska it is a container for visual and audio data.

ISO (Base Media File Format)
ISO base media file format is directly based on Apple’s QuickTime container format. It was developed by MPEG (ISO/IEC JTC1/SC29/WG11). The first MP4 file format specification was created on the basis of the QuickTime format specification published in 2001. The MP4 file format known as "version 1" was published in 2001 as ISO/IEC 14496-1:2001, as revision of the MPEG-4 Part 1: Systems. In 2003, the first version of MP4 file format was revised and replaced by MPEG-4 file format (ISO/IEC 14496-14:2003), commonly known as MPEG-4 file format "version 2". The file format was generalized into the ISO Base Media File format (ISO/IEC 14496-12:2004 or ISO/IEC 15444-12:2004), which defines a general structure for time-based media files. It is used as the basis for other file formats in the family such as 3D Bluray ISO also 2D ISO full BD.

TS Transport stream
Transport stream (TS) is specified in MPEG-2, and it is a standard format for transmission and storage of audio, video, and data. Transport Stream is specified in MPEG-2 Part 1, Systems (formally known as ISO/IEC standard 13818-1 or ITU-T Rec. H.222.0). Transport stream specifies a container format encapsulating packetized elementary streams and stream synchronization features for maintaining transmission integrity when the signal is degraded. Transport streams differ from the similarly named program streams in several important ways: program streams are designed for reasonably reliable media, such as discs.

8K   UHD [ Super Hi-Vision ] 
At a resolution of 7680 x 4320 (or 4,320p), 8K is four times the resolution of 4K and 16 times that of 1080p. It might seem mind-boggling to fathom, but it’s a technology that already exists, and manufacturers have hinted that production could start in just four years. This does raise a question over 4K’s long-term viability because it may turn out to be a stepping stone to 8K, much like 720p was quickly overtaken by 1080p after a short time. Japan’s national broadcaster, NHK, has been pushing 8K, suggesting that H.265 compression is a major step in the right direction. The BBC shot a good portion of the 2012 Summer Olympics in London in 8K last year. That being said, it doesn’t mean 4K is on the way out already. The challenges broadcasters and content owners have faced with 4K would still be problematic when dealing with 8K. The HDMI and bandwidth issues would have to be worked out to handle it. If they are, then it’s not out of the realm of possibility that we’d be upgrading to 8K in five years, but it’s to soon to say for sure right now.

4K  UHD [Ultra High Definition]
4k is the new big thing in display technology, 4K UHD (2160p), 4K UHD is a resolution of 3,840 pixels × 2,160p. Other side [8K UHD which is 7680 pixels × 4320p], New 4K UHD maximum Picture Expanded Color Blu-Rays. Manufacturers just can’t seem to agree on what to call it. Basically, 4K or Ultra HD is four times the resolution of 1080p, which is technically supposed to measure 4,096 x ,2160 pixels (or 2160p), Recently, a Consumer Electronics Association (CEA) group decided that, to end confusion and make marketing easier, Ultra HD should be the official name for the new resolution standard. Unfortunately, people have been calling it 4K for long enough that making the transition to Ultra HD hasn’t been so smooth. Some manufacturers, like Sony, insist on calling it 4K. The main benefit is better picture quality. The higher resolution of 4K means there are 8 million pixels onscreen compared to the 2 million in a 1080p display. If you thought 1080p HD was already sharp and detailed, 4K can take that even further because the pixels are four times smaller. This is partly why 4K Ultra HD has been pushed for larger screen sizes — the extra pixels have a bigger impact on a huge display.

Blu-Ray [1080p FullHD]
Blu-ray (not Blue-ray) also known as Blu-ray Disc (BD), is the name of a new optical disc format jointly developed by the Blu-ray Disc Association (BDA), a group of the world's leading consumer electronics, personal computer and media manufacturers. The format was developed to enable recording, rewriting and playback of high-definition video (HD), as well as storing large amounts of data. The format offers Big storage capacity and can hold up to 25GB on a single-layer disc and 50GB on a dual-layer disc. This extra capacity combined with the use of advanced video and audio codecs will offer consumers an unprecedented HD experience.

REMUX - Blu-Ray
A Blu-ray Disc to another container format or just stripping the disc of menus and bonus material while keeping the contents of its audio and video streams intact, guaranteeing the exact 1:1 movie quality as on original disk.

HEVC Video
High Efficiency Video Coding (HEVC) is a video compression format, a successor to H.264/MPEG-4 AVC, that was jointly developed by the ISO/IEC Moving Picture Experts Group (MPEG) and ITU-T Video Coding Experts Group (VCEG) as ISO/IEC 23008-2 MPEG-H Part 2 and ITU-T H.265, MPEG and VCEG established a Joint Collaborative Team on Video Coding (JCT-VC) to develop the HEVC standard.

HEVC is said to double the data compression ratio compared to H.264/MPEG-4 AVC at the same level of video quality. It can alternatively be used to provide substantially improved video quality at the same bit rate. It can support 8K UHD and resolutions up to 8192x4320p.

HEVC, or H.265 is the successor to H.264 and strives to deliver video with equivalent quality with bitrate savings of up to 50 percent. HEVC is critical for streaming high-quality video even in congested network environments, and will be a driving factor in the delivery of 4K & 8K content to new Ultra HD displays.

AVC / MPEG-4 AVC Video
H.264, also known as MPEG-4 AVC (Advanced Video Coding), is a video compression standard that offers significantly greater compression than its predecessors.The standard offers up to twice the compression of MPEG-4 ASP (Advanced Simple Profile). In addition to improvements in perceptual quality, x264 for encoding video streams into the H.264/MPEG-4 AVC format.

MVC Video
Multiview Video Coding (MVC) is an amendment to H.264/MPEG-4 AVC video compression standard developed with joint efforts by MPEG/VCEG that enables efficient encoding of sequences captured simultaneously from multiple cameras using a single video stream.

MVC is intended for encoding stereoscopic (two-view) video, as well as free viewpoint television and multi-view 3D television. The Stereo High profile has been standardized in June 2009; the profile is based on MVC toolset and is used in stereoscopic Blu-ray 3D releases.

MVC stream is backward compatible with H.264/AVC, which allows older devices and software to decode stereoscopic video streams, ignoring additional information for the second view.

VC-1 Video
SMPTE (Society of Motion Picture and Television Engineers) 421M, informally known as VC-1, which was initially developed as a proprietary video format by Microsoft. It is today a supported standard found in Blu-ray Discs. VC-1 is an evolution of the conventional DCT-based video codec design also found in (H.261, MPEG-1 Part 2, H.262/MPEG-2 Part 2, H.263, and MPEG-4 Part 2). It is widely characterized as an alternative to the latest ITU-T and MPEG video codec standard known as H.264/MPEG-4 AVC. VC-1 contains coding tools for interlaced video sequences as well as progressive encoding. The main goal of VC-1 Advanced Profile development and standardization was to support the compression of interlaced content without first converting it to progressive, making it more attractive to broadcast and video industry professionals.

DTS-HD Master Audio
DTS-HD Master Audio is a lossless audio codec created by Digital Theater System. It was previously known as DTS++.  One goal of the DTS-HD Master Audio format was to allow a bit-to-bit representation of the original movie's studio master soundtrack. To accomplish this, DTS-HD MA supports variable bit rates up to 24.5 Mbit/s on a Blu-ray Disc. The format supports a maximum of 192 kHz sampling frequency and 24-bit depth samples from 2 to 5.1 channels, and 96 kHz/24bit resolution up to 7.1 channels.

Dolby TrueHD Audio
Dolby TrueHD is an advanced lossless multi-channel audio codec developed by Dolby Laboratories which is intended primarily for high-definition home-entertainment equipment such as Blu-ray Disc. In the Blu-ray Dolby TrueHD audiotracks may carry up to 24 bit audio in up to 8 discrete audio channels (7.1 surround) at 96 kHz or up to 6 channels (5.1 surround) at 192 kHz. The maximum encoded bitrate is 18 Mbit/s (the same as the uncompressed rate).

Linear Pulse Code Modulated Audio (LPCM) Audio
Linear pulse-code modulation (LPCM) is a method of encoding audio information digitally. LPCM is the method of encoding generally used for uncompressed audio, Common sample resolutions for LPCM are 8, 16, 20 or 24 bits per sample. Sampling frequencies of 96 kHz or 192 kHz can be used on some newer equipment, with the higher value equating to 6.144 megabit per second for two channels at 16-bit per sample value, allowing 8 channels (7.1 surround) × 48 kHz × 16-bit per sample = 6,144 kbit/s.

DTS-ES (DTS Extended Surround)
DTS-ES (DTS Extended Surround) includes two variants, DTS-ES Matrix and DTS-ES Discrete 6.1, depending on how the sound was originally mastered and stored. DTS-ES Discrete provides 6.1 discrete channels, with a discretely recorded (non-matrixed) center-surround channel; in home theater systems with a 7.1 configuration, DTS-ES Discrete is sometimes notated as DTS-ES 6.1. DTS-ES 96/24 allows the delivery of 6.1 channels of 24-bit, 96 kHz Extended Surround.

DTS (Digital Theater Systems) Audio
DTS is a series of multichannel audio technologies owned by DTS, Inc. (formerly known as Digital Theater Systems). It was known as The Digital Experience until 1995. In 2009 DTS Digital Cinema was purchased by Beaufort International Group Plc. and became known as Datasat Digital Entertainment. The basic and most common version of the format is a 5.1-channel system. Which encodes the audio as five primary (full-range) channels plus a special LFE (low-frequency effects) channel for the subwoofer. DTS 96/24 allows the delivery of 5.1 channels of 24-bit, 96 kHz audio.

AC-3 Compressed Audio (Dolby Digital)
Lossy format designed for the efficient encoding of surround sound, AC-3_A supports 5.1 surround sound. The maximum bitrate in the ATSC AC-3 specification is 640 kb/s. Dolby Digital Plus (rates to 3 Mb/s) will be used in the emerging high definition formats.
