About Item-Level Render Status Bars
An audio clip item in the Timeline may display an individual render bar within the clip
item itself; this indicates that the audio clip requires resampling, or sample rate
conversion, to match the current sequence audio settings. A green render bar indicates
that an audio clip item is being resampled in real time, while a blue-gray render bar
indicates that an audio clip item has been individually rendered so that real-time audio
resampling is no longer necessary. Once an individual audio clip item is rendered, the
clip item refers to the render file instead of the original media file.
The color of the render bar in each audio clip item indicates whether that item needs
sample rate conversion. An audio clip item’s real-time playback status is not indicated.

Real Time and Rendering
There are two advantages to item-level (audio clip item) rendering:
 Item-level rendering reduces the processor demands for audio, leaving more
processing power available for other effects.
 When you move the audio clip item to other tracks or locations in the Timeline, the
clip item does not lose its connection to the render file. This means you don’t have to
rerender the audio clip each time you move it.
