Description | Use the qtIdleRate in conjunction with the global idleRate property to control updating of QT movies. Increasing the qtIdleRate causes less frequent updates, and decreases the amount of CPU time the application uses. By default, the qtIdleRate property is set to 50 (one-twentieth of a second). The qtIdleRate is the time in milliseconds between one update of a player and the next. Updating gives the player object time to redraw the video or other media being played. A higher idle rate will result in smoother playback but will also require more cpu time. LiveCode uses the following heuristics to determine how frequently to idle QT players: If the version of QT < 6 then it idles at the qtIdleRate at all times. If the version of QT >=6 then:
Interactive movies are ones such as QTVR and Flash that need to periodically check for input and update themselves.
