- 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!
