VOB
VOB stands for DVD Video Object.

The VOB file is one of the core files found on DVD-Video discs and contains multiplexed Dolby Digital audio (normally AC3 format) and MPEG-2 video. VOB files on a DVD are numbered as follows: vts_XX_y.vob where XX represents the title and Y the part of the title. There can be 99 titles and 10 parts, although vts_XX_0.vob does not contain any video, usually just menu or navigational information. You can find them on a DVD video disc in a subdirectory labelled VIDEO_TS. View Nidesoft Video Converter

WMV
WMV stands for Windows Media Video.
WMV, developed by Microsoft, is a generic name of Microsoft's video encoding solutions and doesn't necessarily define the technology what it uses. In WMV7, Microsoft has used its own flavour of MPEG4 video encoding technology. You can use a .wmv file either to download and play files or to stream content.
Windows Media Video is used for both streaming and downloading content via the Internet. Microsoft's Windows Media Player, an application bundled with Windows XP operating systems, lets you playback and manage a range of audio and video file types, including, of course, WMA and WMV.

3GP

3GP is the MPEG4 based video format used mostly in mobile terminals, such as mobile phones. This file format is designed for 3rd generation mobile devices.
3GPP is defined by the 3rd Generation Partnership Project and 3GPP is defined by 3rd Generation Partnership Project 2. They are the worldwide standards for the creation, delivery and playback of multimedia over 3rd generation. These standards seek to provide uniform delivery of rich multimedia over newly evolved, broadband mobile networks (3rd generation networks) to the latest multimedia-enabled wireless devices, such as cell phones.

AVI

Stands for Audio Video Interleaved, storing sound and moving pictures in RIFF format developed by Microsoft. An AVI file can use different codecs and formats so there is no set format for an AVI file unlike for example standard VCD video which sets a standard for resolution, bitrates, and codecs used.

FLV

SWF is not the only Flash format. FLV files (Flash Video Files) are a binary file format that delivers "bitmapped" video, limited to one video and one audio stream per file, over the Internet to the Macromedia Flash Player version 7. FLV content may also be associated with SWF files by ActionScript external references. FLV format can also imported into Macromedia Flash Authoring tool. Unlike SWF format, FLV do not have maximum of 16000
Topframes limitation and ideally for large video file size.

PSP

PSP stands for PlayStation Portable.

The Sony PSP is a slick portable gaming system highlighted by an impressive wide-screen display and PS2-like graphics. It also boasts built-in Wi-Fi, a Web browser, and the ability to play music and videos, as well as to store images.

Flash

Flash is a multimedia platform originally acquired by Macromedia and currently developed and distributed by Adobe Systems. Since its introduction in 1996, Flash has become a popular method for adding animation and interactivity to web pages. Flash enables you to create interactive "movies" on the web. It uses vector graphics, which means that the graphics can be scaled to any size without losing clarity/quality.

MP4

MP4, also know as MPEG-4, is a multimedia container format. It is most commonly used to store digital audio and digital video streams, especially those defined by MPEG, but can also be used to store other data such as subtitles and still images. Like most modern container formats, MP4 allows streaming over the Internet. A separate hint track is used to include streaming information in the file. Now lots of popular players support MP4 files such as Blackberry, iPod, iPhone, Apple TV, Zune, PSP and Walkman.

MKV

MKV, also known as Matroska, is an open standard free container format, a file format that can hold an unlimited number of video, audio, picture or subtitle tracks inside a single file. It is intended to serve as a universal format for storing common multimedia content, like movies or TV shows. Matroska is similar in conception to other containers like AVI, MP4 or ASF, but is entirely open in specification, with implementations consisting mostly of open source software. Matroska file types are .MKV for video (with subtitles and audio), .MKA for audio-only files and .MKS for subtitles only. The most common use of .MKV files is to store HD video files.

MOD

MOD files are JVC's implementation of MPEG-2 transport streams, similar to a VOB file on a DVD or the M2T files used on Sony hard drive camcorders. A MOD file contains a set of instruments in the form of samples, a number of patterns indicating how and when the samples are to be played, and a list of what patterns to play in what order. MOD format is being used in standard definition camcorders manufactured by JVC, Panasonic and Canon.

MPEG

MPEG (pronounced M-peg), which stands for Moving Picture Experts Group, is the name of a family of standards used for coding audio-visual information (e.g., movies, video, music) in a digital compressed format. The major advantage of MPEG compared to other video and audio coding formats is that MPEG files are much smaller for the same quality. This is because MPEG uses very sophisticated compression techniques.

MP3

MP3 stands for MPEG1 (or MPEG2) Audio Layer III. MP3 is a popular compression format used for audio files on computers and portable devices. It is a method to store good quality audio into small files.

WAV

WAV, short for Waveform audio format, is a Microsoft and IBM audio file format standard for storing an audio itstream on PCs. It is an application of the RIFF bitstream format method for storing data in “chunks”, and thus also close to the IFF and the AIFF format. It is the main format used on Windows systems for raw and typically uncompressed audio.

OGG

Ogg Vorbis is a fully open, non-proprietary, patent-and-royalty-free, general-purpose compressed audio format for mid to high quality (8kHz-48.0kHz, 16+ bit, polyphonic) audio and music at fixed and variable bitrates from 16 to 128 kbps/channel. Vorbis is the first of a planned family of Ogg multimedia coding formats being developed as part of Xiph.org's Ogg multimedia project.

MSWMM

MSWMM is Windows Movie Maker Project.

This webpage includes following information: MSWMM description, user guides and software to open/edit MSWMM format file. Movie created with Windows Movie Maker; contains the movie timeline, transitions, and references to video clips, audio files, and still images used by the movie.Windows Movie Maker allows the user to combine and edit content saved within an MSWMM file; once the movie is finished, it can be exported in a standard video format or burned to a DVD.

M4A

Files in .M4A format are actually the audio layer of (non-video) MPEG 4 movies. M4A is slated to become the new standard for audio file compression. This format is also known as Apple Lossless, Apple Lossless Encoder, or ALE. It is a new codec designed to provide lossless encoding in less storage space.

AAC

Advanced Audio Coding (AAC) is a standard compression and encoding format for digital audio. AAC is part of the MPEG-4 standard, which was established by the Moving Pictures Experts Group (MPEG), the committee that developed the MPEG-1 and MPEG-2 standards that are used all over the world in CD-ROM and DVD discs and other technologies.

RM

RM - stands for Real Media.
Real Media is one of the most popular formats for streaming content on the Interne t, RealMedia includes the RealAudio codec for sound clips and RealVideo codec for movies. RealAudio and RealVideo files are often given the common RealMedia ".RM" file extension. RealMedia files are often heavily compressed so they can stream over dial-up Internet connections.

Amr

AMR (Audio/Modem Riser) is a specification developed by Intel for packaging the analog I/O audio functions of modem circuitry together with a codec chip (which converts back and forth from analog to digital) on a small board that plugs directly into a computer's motherboard . The small board is called a riser because it rises above the motherboard rather than laying flatly on it. Having this circuitry on a riser means that it doesn't have to be part of the motherboard itself. Because getting certification for the manufacture of a new motherboard design is a lengthy process, removing this function from the motherboard provides more flexibility for manufacturers and allows advances in audio modem design to be implemented more easily. Another specification, MDC (Mobile Daughter Card) is the equivalent of AMR but for use in mobile computers.

Au

The Au file format is a simple audio file format introduced by Sun Microsystems. The format was common on NeXT systems and on early web pages. Originally it was headerless, being simply 8-bit µ-law-encoded data at an 8000 Hz sample rate. Hardware from other vendors often used sample rates as high as 8192 Hz, often integer factors of video clock signals. Newer files have a header that consists of six 32-bit words, an optional information chunk and then the data (in big endian format).

Ra

RA - RealAudio
RealAudio was developed by RealNetworks and supports FM-stereo-quality sound. To hear a Web page that includes a RealAudio sound file, you need a RealAudio player or plug-in, a program that is freely available from a number of places.

3GP

3GP is a multimedia container format defined by the Third Generation Partnership Project (3GPP) for use on 3G mobile phones but can also be played on some 2G and 4G phones.

MP2

MP2 (sometimes also called Musicam) is short for MPEG-1 Audio Layer II. MP2 files usually have an extension of .mp2 but sometimes .mpa is used instead. MP2 has largely been superseded by MP3 (MPEG-1 Audio Layer III) for file sharing and CD ripping, but it remains a dominant standard for audio broadcasting in Europe as part of the DAB digital radio and DVB digital television standards.

3G2

3GPP2 (for CDMA-based Phones, may have filename extension .3g2)

MOV

.mov is proprietary format of Apple and it's only possible to play it with their own software "Quick Time" (it's possible to play some old videos that are encoded with old version of quicktime codec but you probably meant about those new videos like movie trailers) because there are no separate decoders like for DivX, XviD and other codecs than decoder itself it's integrated in executable of program and therefore you can not play it with BSPlayer.

ASF

ASF (Advanced Streaming Format) is a file format that stores audio and video information and is specially designed to run over networks like the Internet. It is a highly flexible and compressed format that contains streaming audio, video, slide shows, and synchronized events. ASF enables content to be delivered to you as a continuous flow of data with little wait time before playback begins. This means that you no longer have to wait for your audio and video files to fully download before starting to view them. You simply launch the Windows Media Player and begin.

MPG

MPG video file is a variant of the MPEG (Moving Picture Experts Group) video and audio compression format, optimized for broadcast quality video. MPG videos have the file extension .mpg.
