Controlling Real-Time Effects Playback
When the Avid editing application is unable to maintain real-time playback of an effects sequence, there are a number of ways you can attempt to ensure that the sequence plays back successfully in real time.
 | |
If possible, start playback earlier in the sequence, before the effects
that are causing difficulties begin.
|
This allows the Avid editing application to begin processing some of
the effects frames before it must display them, decreasing the chance
of difficulties with playback.
| |
Use the Expert Render command on those parts of the sequence where
the Avid editing application had difficulties during playback.
|
| |
Use the Video Quality Menu button to select a lower quality for
playback.
|
| |
In the Video Display Settings dialog box, increase the number of
seconds of video to prefill.
|
This setting instructs the Avid editing application to delay the
beginning of playback by the number of seconds you specify. During
this time, the application processes frames in advance and stores them
in memory. When playback begins, the application starts to display the
preprocessed frames while it continues to process new ones. The
application will continue to play back the sequence successfully in real
time unless it exhausts its supply of preprocessed frames. By accepting
a delay at the beginning of playback, you increase the likelihood that
the application will play the material successfully. The maximum
delay you can specify is 10áseconds.
The Video Display settings dialog box is available in the Settings scroll
list of the Project window.
 | |
If the amount of memory available is limited, the Avid editing application
might not be able to prefill the full number of seconds that you specify. As a
result, the delay you experience before playback begins might be less than
the number of seconds you specify. It cannot be more than that number.
