Playing Digital Video With Lingo - MACROMEDIA DIRECTOR MX-USING DIRECTOR MX Use Manual

Playing digital video with Lingo

Lingo can take advantage of the most important and powerful features of digital video. Besides
playing digital video linearly, Lingo can pause, stop, and rewind a video. These abilities are useful
for jumping to segments within a digital video and for emulating a typical digital video control
panel. This last feature is especially useful for AVI digital video, which has no control panel.
Lingo also lets you work with individual tracks in a digital video by determining the tracks'
content and position and turning these tracks on and off.
For information on using Lingo with RealMedia movies, see "Using RealMedia content in
Director" on page 341.
