Defined by Microsoft, AVI stands for Audio
Video Interleave. It is a special case of the RIFF
(Resource Interchange File Format). AVI is the most common format for audio/video
data on the PC.
AVI is Microsoft's response to Apple's QuickTime
technology. Early AVI files were limited on choice of video and audio codecs,
quality, and resolution. However, with the introduction of DirectShow, AVI became
a very flexible and powerful architecture. Some newer codecs including DivX
and XviD enable AVI files to have similar
or even better quality than DVD.
Quicktime is a multimedia development,
storage, and playback technology from Apple. Quicktime files combine sound,
text, animation, and video in a single file. Using a Quicktime player that either
comes with a Web browser or can be downloaded from Apple or the browser company,
you can view and control brief multimedia sequences.
As a multimedia stardand, QuickTime is not purely linear. It could contain
interactivity and causes problems when converting to other video formats.
A lot of digital cameras record video in QuickTime support.
