AVI Video Format

AVI combines audio and video into a single file in a standard container to allow simultaneous playback. It’s advatage is it’s simple architecture, due to which AVI runs on a number of different systems like Windows, Mac’s, Linux, Unix and is supported by all most popular web-browsers.

AVI format is one of the oldest video formtas. Since the day of it was developerd there have appeared a lot of AVI codec’s created by both vendors and individuals. So now there are hundreds of avi files that look similar but are completely different inside. That may cause trouble when converting avi files to other formats. Not all converting utilities in fact support all modifications of avi files. Not to get trapped, use Total Movie Converter. It converts almost all avi files with ease. Now you can convert your avi files and upload them to iPod, iPphone, any smart phone, xBox, Archos, PSP, Zune. Handle Total Movie Converter via GUI, command line or Windows right-click popup menu (select avi file, make right button mouse click and press convert to).

The AVI file type is primarily associated with ‘Audio Video Interleave File’. Recent files might be compressed with one or another codecs (like DivX and XviD). It can also be seen with VLC Player, MPlayer, The KMPlayer.


Choice of codecs means you can achieve a high rate compression if you experiment.

AVI can play in mainstream media players such as Windows Media Player.

AVI Can be used as a starting point to create playable DVDs.

AVI does not provide a standardized way to encode aspect ratio information, with the result that players cannot select the right one automatically (though it may be possible to do so manually).

Cannot contain some specific types of VBR data(such as MP3 audio at sample rates below 32KHz) reliably.

Overhead for AVI files at the resolutions and frame rates normally used to encode feature films is about 5 MB per hour of video, the significance of which varies with the application.

AVI was not intended to contain video using any compression technique which requires access to future video frame data beyond the current frame. Approaches exist to support modern video compression techniques (e.g. MPEG-4) which rely on this functionality, although this is beyond the intent of the original specification and may cause problems with playback software which does not anticipate this use.

AVI is not intended to contain variable frame rate material. Workarounds for this limitation increase overhead dramatically.

There are several competing approaches to including time-code in AVI files, which affects usability of the format in film and television postproduction (although it is widely used). An equivalent of the Broadcast Wave extensions, designed to standardize postproduction metadata for wave audio files, has not emerged.
