Indeo Video Interactive

General Information
Indeo Video Interactive (IVI) is a very high-quality, wavelet-based codec. It provides excellent image quality, but requires a high-end Pentium for playback. IVI is an entirely different technology from Indeo 3.

IVI provides a range of interactive features which go beyond the traditional services provided by codecs. These include chromakeyed transparency, and hot spot support.
There are currently two main versions of IVI. Version 4 is included in QuickTime 3 for Windows; Version 5 is for DirectShow only. Neither version currently runs on the Macintosh, so any files encoded with IVI will not work cross-platform. Version 5 is very similar to 4, but uses an improved wavelet algorithm for better compression.
