What is IVF?

IVF stands for Indeo Video Format, most commanly known as Intel Indeo (Intel developed this video codec).
This codec was quite popular in 1990s as it was the first one to allow full-speed video playback without using hardware acceleration.
Later Intel Indeo video codec was beaten by MPEG standarts and lost it's popularity.
Nowadays it is quite rare and commonly used in video game cut scene videos.
Not all modern decoders support IVF files.
