Q What guidelines are there for the maximum movie data rate when
playing from a CD-ROM for Cinepak 320x240 15fps and 22k 8bit audio?
A Many double-speed CD-ROM drives do not deliver sustained
data-transfer rates above 200KB per second under Windows. Therefore, we recommend 150-180KB
per second as a practical limit for all tracks be played concurrently under QuickTime for Windows.
Depending upon the movie's video content, a Cinepak compressed 320x240x15fps video track and a 22K,
8-bit audio track should fit into these data-rate constraints. For better audio at the same data rate,
use 44.1K, 16-bit audio with IMA 4:1 compression.
