Movie Files maybe one of the following:

1. DivX: The DivX Codec is popular due to its ability to compress lengthy video segments into small sizes while maintaining relatively high visual quality. It is one of several codecs commonly associated with ripping, where audio and video multimedia are transferred to a hard disk and transcoded.



2. AVI - meaning Audio Video Interleaved is a compression system provided by Microsoft. Sometimes AVI files are also called as RIFF (The abbreviation is not that very important!). This video can be played as is on the Windows Media Player 11.0.



3. Is another encoding method - based on previous lossy versions of MPEG-1 and MPEG 2.



These are the main types of video files.





The types of audio files are:

MP3 - Most widely used

mp3PRO, AAC, and MP2 - are older versions of MP3.

WMA - Windows Media Audio - Provided by Microsoft. Newer versions include WMA Pro.

WAV - is a Microsoft and IBM audio file format standard for storing audio on PCs. Has no comrpession alogrithm to it.

well there are quite a few, but i will try to highlight some of the more common ones that i have encountered.



wmv - windows media video, usually plays with windows media player

avi - plays also on windows media player and quicktime as well.

mov - that is stritcly a quicktime video file

mpeg & mpeg 2 - windowns media player, real player

m4a - seen this as both an audio and a video file, i believe it has to do with ipods and such. most of the time real player is the only think that will play this file.

mp3 - strictly audio/music files

there is also an extension for real player files but i forgot what that was, but if i remember i will let you know. Hope this helps MG, take care.........Jay

ok avi and mpg are video formats that have both video and sound.. divx usually refers to the divx codec that tells a media player how to compress a video in that format.. it's based on mpeg4 which is a video file... pretty much makes videos more universal. mp3 is a audio (music) file

Actually new file formats and extensions are created daily so it's kind of impossible to learn all the different types.



However, I know of a great website called http://filext.com/ which will describe the file format and will give you the name of the program to use for it. All have to do is just type the ending extension of the file you wish to search for in the search box at the site.

mp3 are music files

Divx videos with AVI extentions are for movies and playable on computers and DVD players that accept divx files

mpg files can be played with video software on your computer



Try VLC media player, the best player so far

you ought to save the video as WMV video format, not as a progect. Tenorshare Video Converter is the all-powerful video converter software that helps all forms of video and audio formats conversion. with it, you are able to rather convert WMV video to AVI, MOV,and so on.

VIDEO FORMAT



A video format describes how one device sends video pictures to another device, such as the way that a DVD player sends pictures to a television, or a computer to a monitor. More formally, the video format describes the sequence and structure of frames that create the moving video image.

Video formats are commonly known in the domain of commercial broadcast and consumer devices; most notably to date, these are the analog video formats of NTSC, PAL, and SECAM. However, video formats also describe the digital equivalents of the commercial formats, the aging custom military uses of analog video (such as RS-170 and RS-343), the increasingly important video formats used with computers, and even such offbeat formats such as color field sequential.

Video formats were originally designed for display devices such as a CRTs. However, because other kinds of displays have common source material and because video formats enjoy wide adoption and have convenient organization, video formats are a common means to describe the structure of displayed visual information for a variety of graphical output devices.



Analog video formats

* NTSC

* PAL

* SECAM

Digital Video Formats



These are MPEG2 based terrestrial broadcast video formats

* ATSC

* DVB

* ISDB

Open File Formats



* wav - standard audio file format used mainly in Windows PCs. Commonly used for storing uncompressed (PCM), CD-quality sound files, which means that they can be large in size - around 10MB per minute of music. It is less well known that wave files can also be encoded with a variety of codecs to reduce the file size (for example the GSM or mp3 codecs). Wav files use a RIFF structure.

* ogg - a free, open source container format supporting a variety of codecs, the most popular of which is the audio codec Vorbis. Vorbis offers better compression than MP3 but is less popular.

* flac - a lossless compression codec. You can think of lossless compression as like zip but for audio. If you compress a PCM file to flac and then restore it again it will be a perfect copy of the original. (All the other codecs discussed here are lossy which means a small part of the quality is lost). The cost of this losslessness is that the compression ratio is not good. Flac is recommended for archiving PCM files where quality is important (eg. broadcast or music use).

* aiff - the standard audio file format used by Apple. It is like a wav file for the Mac.

* raw - a raw file can contain audio in any codec but is usually used with PCM audio data. It is rarely used except for technical tests.

* au - the standard audio file format used by Sun, Unix and Java. The audio in au files can be PCM or compressed with the μ-law, a-μlaw or G729 codecs.



Open File Formats



* mp3 - the MPEG Layer-3 format is the most popular format for downloading and storing music. By eliminating portions of the audio file that are essentially inaudible, mp3 files are compressed to roughly one-tenth the size of an equivalent PCM file while maintaining good audio quality. The mp3 format is recommended for music storage. It is not that good for voice storage.

* gsm - designed for telphony use in Europe, gsm is a very practical format for telephone quality voice. It makes a good compromise between file size and quality. Note that wav files can also be encoded with the gsm codec.

* dct - A variable codec format designed for dictation. It has dictation header information and can be encrypted (often required by medical confidentiality laws).

* vox - the vox format most commonly uses the Dialogic ADPCM (Adaptive Differential Pulse Code Modulation) codec. Similar to other ADPCM formats, it compresses to 4-bits. Vox format files are similar to wave files except that the vox files contain no information about the file itself so the codec sample rate and number of channels must first be specified in order to play a vox file.

* aac - the Advanced Audio Coding format is based on the MPEG2 and MPEG4 standards. aac files are usually ADTS or ADIF containers.

* mp4/m4a - MPEG-4 audio most often AAC but sometimes MP2/MP3



Proprietary Formats



* wma - the popular Windows Media Audio format owned by Microsoft. Designed with Digital Rights Management (DRM) abilities for copy protection.

* atrac (.wav) - the older style Sony ATRAC format. It always has a .wav file extension. To open these files simply install the ATRAC3 drivers.

* ra - a Real Audio format designed for streaming audio over the Internet. The .ra format allows files to be stored in a self-contained fashion on a computer, with all of the audio data contained inside the file itself.

* ram - a text file that contains a link to the Internet address where the Real Audio file is stored. The .ram file contains no audio data itself.

* dss - Digital Speech Standard files are an Olympus proprietary format. It is a fairly old and poor codec. Prefer gsm or mp3 where the recorder allows. It allows additional data to be held in the file header.

* msv - a Sony proprietary format for Memory Stick compressed voice files.

* dvf - a Sony proprietary format for compressed voice files; commonly used by Sony dictation recorders.

* m4p - A proprietary version of AAC in MP4 with Digital Rights Management developed by Apple for use in music downloaded from their iTunes Music Store.
