Indeo Video Interactive
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.
- Requires high-end Pentium for playback.
- Does not provide a cross-platform solution.
