Playing Complex Effect Combinations
If your sequence contains a combination of effects that exceeds the real-time playback capabilities of your Avid editing application, you can achieve successful playback using the following additional techniques:
  Render some or all of the effects. For more information, see Rendering Effects.
  Consider rendering transition effects such as the Dissolve effect or wipe effects first; they take less time to render than titles or segment effects.
  Use the Submaster effect to reduce the amount of rendering. For more information, see Submaster Editing.
  Perform a mixdown of video tracks. For more information, see Performing a Video Mixdown.
If your sequence contains multiple short clips with multiple real-time effects or images with a high level of complexity, you might exceed the capacity of the hardware to play these in real time, even if these effects would not normally exceed the real-time playback capabilities of your Avid editing application. This results in Video Underrun error messages. In this case, render some of the intermediate effects before playing the sequence. For more information, see ExpertRender.
