Video Formats Introduction

AVI Formats

(DivX, XviD, MS MPEG-4, Uncompressed, Cinepak and other)

AVI stands for Audio Video Interleave. It is a special case of the RIFF (Resource Interchange File Format). AVI is defined by Microsoft. AVI is the most common format for audio/video data on the PC. AVI is an example of a de facto (by fact) standard.

AVI Files are a special case of RIFF files. RIFF is the Resource Interchange File Format. This is a general purpose format for exchanging multimedia data types that was defined by Microsoft and IBM during their long forgotten alliance.

WMV Formats

Windows Media Video.

Formerly known as .ASF file format from Microsoft. A .WMV file includes a video stream (compressed using MS MPEG4 or WMV1 codec) combined with WMA encoded audio stream. The file format is proprietary and backward incompatible. Currently, dedicated to slow dialup connections, this media format does not allow even sub-VHS video quality due to blurred picture. WMA audio quality, compared to MPEG Layer3 of the same bitrate, isn't better either. You may wish to use Windows Media format to create smallest files that are suitable to send by e-mail, however you must keep in mind that .WMV file works like "one way ticket" - once created, it can't be edited anymore, without horrific quality loss. As opposite, AVI files compressed with MPEG4 video codec are still editable and often it is possible to retain source video quality.
