Indeo Video Interactive

General Information

Overview
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.

Versions
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.

Architectures Supported

QuickTime for Windows: IVI 4.1 (not available for MacOS)
DirectShow: IVI 5.0
Video for Windows: IVI 5.0
