In yesterday's InfoWorld, there were two articles about Microsoft's Video for
Windows -- code named AVI. Windows 3.1 users will be able to play back video
using compression technology from Intel and Microsoft. Initially, Microsoft is
expected to provide a start-up kit for less than $200.

The product will translate Mac QuickTime movies into Video for Windows movies..
SuperMac Technology will make a VideoSpigot for Windows card to let users play
back video in 640x480 -- the board also translated NTSC and PAL and converts
them into compressed files.

On a low end 386-16, movies play in a 160x120 and 15 frames per second -- This
is the same a QuickTime. On a 486 with video co-processor support, movies can
play at full-screen VGA with 16.7 million colors and 30 frames per second.

Disk space?... The article says the beast eats disk space at the rate of 1MB
per 5 seconds of movie!
