Available Real-Time Effects
Video transitions and filters that can play back in real time appear in boldface type in
the Effects tab in the Browser and in the Effects menu. The following effects can play
back in real-time:
 Superimpositions and multiclip playback: Simultaneously superimposed video clip items
in the Timeline with different opacity settings can be played back in real time. Multiclip
playback can also be played back in real time, depending on the number of angles in
the clip. Your disk speed and the processor speed of your computer together
determine how many simultaneous video streams can play back in real time
 Still frames: Still frames and imported graphics can also play back in real time. The
number of still images that play back in real time depends on the size of the Still
Cache set in the Memory & Cache tab of the System Settings window.
The size of the still cache is limited by the total amount of unused physical RAM
installed in your computer. The higher the still cache, the more stills that can be
played back in real time in the currently selected sequence. If another sequence is
opened, the contents of the still cache are automatically replaced with stills from the
new sequence.
 Transitions, filters, and motion effects: Most of the built-in transitions and filters can be
used in real time. With the Unlimited RT setting selected in the Real-Time Effects (RT)
pop-up menu of the Timeline, almost any effect or clip requiring processing can play
back in real time.
You can adjust the
Still Cache slider or enter
a value to change the
number of still images
that play back.
