This is a guide (really a video type dictionary) that explains almost every single video type on the Internet and everything you will run into while torrenting….
You will always run into other weird formats you have never seen before and be like WTH how do i play this….Usually VLC and The K-Lite Codec Pack will help you play all the formats i am about to mention. A link to them is in the 1st format which is the format you will probably see the most in your torrenting years.
Heres it goes!!!
__________________________________________________________
.AVI (Audio Video Interleave)
AVI is a video format from Microsoft. Currently it’s the most common file format for storing audio/video data on the PC. Also it’s a standard video format in the scene. AVI itself doesn’t specify how it should be encoded, so the audio/video can be stored in very various ways. The most commonly used video codecs that use the AVI structure are XViD and DiVX. AVI can be played by almost any video viewing program. When it’s coded with XViD or DiVX you’ll need to download the codec to view it. I prefer K-Lite Codec Pack which usually plays all formats I have ever thrown at it. But also VLC Media Player is a separate program that contains all the codecs with it so there doesn’t have to be any installation and all the codec and video settings are in the program> K-Lite and VLC
.DIVX
Old file format of .avi files encoded with the divx codec. See .AVI. you will rarely see these anymore and usually you can use VLC to play them..
.FLV and .SWF
FLV Files are really just flash files that you usually download of Youtube or other video clip sites. VLC can play these but they’re are other programs like FLV Player that can also play these. Do not get FLV’s mixed with .swf’s found at places like ebaumsworld.com. Usually you can save .SWF’s easily and just play them with your brower.
.MKV (Matroska Video)
A .mkv file is a very modern multimedia container file that contains one or more tracks, each of which store a particular type of data, such as audio, video, effects, or text (for subtitles, for example). The .mkv is unique because it supports almost any format, and it has advanced features, like: chapters, selectable subtitles/audio, stream able for Internet and menu’s. In the scene, this format is often used for high definition content, in combination with modern codecs like: x264 and h264. This is also pretty rare but you probably will see it in your lifetime especially if you like high-definition.
.MOV (MOVie)
A .mov file is an Apple Quicktime movie file. A .mov file functions as a multimedia container file that contains one or more tracks, each of which store a particular type of data, such as audio, video, effects, or text (for subtitles, for example). Each track in turn contains track media, either the digitally-encoded media stream (using a specific codec such as mp3, jpeg, divx) or a data reference to the media stored in another file or elsewhere on a network. I usually do not use .mov files because their quality is not super great, but you will see them especially with little clips and such. These can be played with Quicktime and VLC or K-lite.
.MP4 (MPEG Audio Layer-4)
MPEG-4 -encoded audio or video file, using MPEG-4’s container format. MP4 files can be played by alternative systems like Apple computers and iPod’s. These are usually found on PSP’s and Ipods but can be used to make very small files for other portable systems like Mobile Phones.
.MPG / MPEG
MPEG-1 or MPEG-2 -encoded video file. A video standard developed by MPEG Group. MPEG-2 is not a successor for MPEG-1, but an addition instead — both of these formats have their own purposes in life; MPEG-1 is meant for medium-bandwidth usage and MPEG-2 is meant for high-bandwidth/broadband usage. Most commonly MPEG-2 is used in digital TVs, DVD’s and SVCD’s. MPEG-1 is mostly found in KVCD’s and VCD’s and other small movie files.
.ratDVD
A .ratDVD file has been created with the software ratDVD. ratDVD can compress an entire DVD movie to one single file including menus with full functionality, all extras, all audio tracks, all angles and any other material on the disc. The result .ratDVD file is usually several gigabytes smaller, but the quality is not so good. Also, it’s packed and compressed a lot. These are extremely rare now and you will probably never come across one.
.VOB (Video Object File)
It is one of the core files found on DVD-Video discs and contains the actual movie data. Basically VOB file is just a basic MPEG-2 system stream, meaning that it is a file that contains multiplexed MPEG-2 video stream, audio streams (normally AC3 and DTS formats) and subtitle streams. Usually on a DVD there will be multiple .VOB files. If you ever want to rip the main movie from a DVD and put it on your computer as 1 file, i recommend using VOB2MPG.
.WMV (Windows Media Video)
WMV is a generic name of Microsoft’s video encoding solutions and doesn’t necessarily define the technology what it uses — since version 7 (WMV7) Microsoft has used its own flavor of MPEG-4 video encoding technology (not very surprising, it’s not compatible with other MPEG-4 technologies). DivX video format is originally based on hacked WMV codec. The latest versions of WMV don’t have much in common with MPEG-4 anymore, but use Microsoft’s own video encoding technologies instead. The only releases which are in .WMV format are ususlly porn clips (since you download them as .WMV from the web and don’t require a re-encode) and High-Quality Xbox vids.
.XVID
Old file format of .avi files encoded with the xvid codec. See .avi at the top of the page for more info.
Video File Container Formats
.ISO
An .iso file is a complete copy of a CD or DVD, stored into 1 file. The extension comes from the full name of the CD-ROM and DVD-ROM file system specification, ISO 9660. .ISO files are one of the two most standard file formats for image files in the scene. It can be burned to a CD/DVD or virtually mounted.
I recommend a program like PowerISO to handle ISO files by Viewing, Editing, Extracting, Mounting, and Burning ISO Files.
.IMG (Image)
An .img file is a complete copy of a cd or dvd, stored into 1 file. If it’s ripped with CloneCD
the .img file should also be accompanied by a .ccd and a .sub file. .IMG files are one of the two most standard file formats for image files in the scene. It can be burned to a CD/DVD or virtually mounted. I still recommend PowerISO for this sort of thing since it does support the handling of this format also. Meaning it can do all the same things with a .IMG as it can do with a .ISO.
.MDF
If it is a rather large file, e.g. 650 MB, then it is most likely a CD image. If it is a file bigger than 700MB then it is a DVD Image. These MDF image files are created using a CD/DVD CD/DVD image file editor (and CD burner and CD/DVD backup tool) called MagicISO. But also these can be burned and handled with PowerISO.
CAM –
A cam is a theater rip usually done with a digital video camera. A mini tripod is sometimes used, but a lot of the time this wont be possible, so the camera make shake. Also seating placement isn’t always idle, and it might be filmed from an angle. If cropped properly, this is hard to tell unless there’s text on the screen, but a lot of times these are left with triangular borders on the top and bottom of the screen. Sound is taken from the onboard microphone of the camera, and especially in comedies, laughter can often be heard during the film. Due to these factors picture and sound quality are usually quite poor, but sometimes we’re lucky, and the theater will be fairly empty and a fairly clear signal will be heard.
TELESYNC (TS) –
A telesync is the same spec as a CAM except it uses an external audio source (most likely an audio jack in the chair for hard of hearing people). A direct audio source does not ensure a good quality audio source, as a lot of background noise can interfere. A lot of the times a telesync is filmed in an empty cinema or from the projection booth with a professional camera, giving a better picture quality. Quality ranges drastically, check the sample before downloading the full release. A high percentage of Telesyncs are CAMs that have been mislabeled.
TELECINE (TC) –
A telecine machine copies the film digitally from the reels. Sound and picture should be very good, but due to the equipment involved and cost telecines are fairly uncommon. Generally the film will be in correct aspect ratio, although 4:3 telecines have existed. A great example is the JURASSIC PARK 3 TC done last year. TC should not be confused with TimeCode , which is a visible counter on screen throughout the film.
SCREENER (SCR) –
A pre VHS tape, sent to rental stores, and various other places for promotional use. A screener is supplied on a VHS tape, and is usually in a 4:3 (full screen) a/r, although letterboxed screeners are sometimes found. The main draw back is a “ticker” (a message that scrolls past at the bottom of the screen, with the copyright and anti-copy telephone number). Also, if the tape contains any serial numbers, or any other markings that could lead to the source of the tape, these will have to be blocked, usually with a black mark over the section. This is sometimes only for a few seconds, but unfortunately on some copies this will last for the entire film, and some can be quite big. Depending on the equipment used, screener quality can range from excellent if done from a MASTER copy, to very poor if done on an old VHS recorder thru poor capture equipment on a copied tape. Most screeners are transferred to VCD, but a few attempts at SVCD have occurred, some looking better than others.
DVD-SCREENER (DVDscr) –
Same premise as a screener, but transferred off a DVD. Usually letterbox , but without the extras that a DVD retail would contain. The ticker is not usually in the black bars, and will disrupt the viewing. If the ripper has any skill, a DVDscr should be very good. Usually transferred to SVCD or DivX/XviD.
DVDRip –
A copy of the final released DVD. If possible this is released PRE retail (for example, Star Wars episode 2) again, should be excellent quality. DVDrips are released in SVCD and DivX/XviD.
VHSRip –
Transferred off a retail VHS, mainly skating/sports videos and XXX releases.
TVRip –
TV episode that is either from Network (capped using digital cable/satellite boxes are preferable) or PRE-AIR from satellite feeds sending the program around to networks a few days earlier (do not contain “dogs” but sometimes have flickers etc) Some programs such as WWF Raw Is War contain extra parts, and the “dark matches” and camera/commentary tests are included on the rips. PDTV is capped from a digital TV PCI card, generally giving the best results, and groups tend to release in SVCD for these. VCD/SVCD/DivX/XviD rips are all supported by the TV scene.
WORKPRINT (WP) –
A workprint is a copy of the film that has not been finished. It can be missing scenes, music, and quality can range from excellent to very poor. Some WPs are very different from the final print (Men In Black is missing all the aliens, and has actors in their places) and others can contain extra scenes (Jay and Silent Bob) . WPs can be nice additions to the collection once a good quality final has been obtained.
DivX Re-Enc –
A DivX re-enc is a film that has been taken from its original VCD source, and re-encoded into a small DivX file. Most commonly found on file sharers, these are usually labeled something like Film.Name.Group(1of2) etc. Common groups are SMR and TND. These aren’t really worth downloading, unless you’re that unsure about a film u only want a 200mb copy of it. Generally avoid.
Formats
VCD –
VCD is an mpeg1 based format, with a constant bitrate of 1150kbit at a resolution of 352×240 (NTCS). VCDs are generally used for lower quality transfers (CAM/TS/TC/Screener(VHS)/TVrip(analogue) in order to make smaller file sizes, and fit as much on a single disc as possible. Both VCDs and SVCDs are timed in minutes, rather than MB, so when looking at an mpeg, it may appear larger than the disc capacity, and in reality u can fit 74min on a CDR74.
SVCD –
SVCD is an mpeg2 based (same as DVD) which allows variable bit-rates of up to 2500kbits at a resolution of 480×480 (NTSC) which is then decompressed into a 4:3 aspect ratio when played back. Due to the variable bit-rate, the length you can fit on a single CDR is not fixed, but generally between 35-60 Mins are the most common. To get a better SVCD encode using variable bit-rates, it is important to use multiple “passes”. this takes a lot longer, but the results are far clearer.
XVCD/XSVCD –
These are basically VCD/SVCD that don’t obey the “rules”. They are both capable of much higher resolutions and bit-rates, but it all depends on the player to whether the disc can be played. X(S)VCD are total non-standards, and are usually for home-ripping by people who don’t intend to release them.
DivX / XviD –
DivX is a format designed for multimedia platforms. It uses two codecs, one low motion, one high motion. most older films were encoded in low motion only, and they have problems with high motion too. A method known as SBC (Smart Bit-rate Control) was developed which switches codecs at the encoding stage, making a much better print. The format is Ana orphic and the bit-rate/resolution are interchangeable. The majority of PROPER DivX rips (not Re-Encs) are taken from DVDs, and generally up to 2hours in good quality is possible per disc. Various codecs exist, most popular being the original Divx3.11a and the new XviD codecs.
CVD –
CVD is a combination of VCD and SVCD formats, and is generally supported by a majority of DVD players. It supports MPEG2 bit-rates of SVCD, but uses a resolution of 352×480(ntsc) as the horizontal resolution is generally less important. Currently no groups release in CVD.
DVD-R –
Is the recordable DVD solution that seems to be the most popular (out of DVD-RAM, DVD-R and DVD+R). it holds 4.7gb of data per side, and double sided discs are available, so discs can hold nearly 10gb in some circumstances. SVCD mpeg2 images must be converted before they can be burnt to DVD-R and played successfully. DVD>DVDR copies are possible, but sometimes extras/languages have to be removed to stick within the available 4.7gb.
MiniDVD –
MiniDVD/cDVD is the same format as DVD but on a standard CDR/CDRW. Because of the high resolution/bit-rates, its only possible to fit about 18-21 mins of footage per disc, and the format is only compatible with a few players.
