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, and 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.
Audio render bars in the
Timeline indicate audio
tracks that have been
mixed down (all tracks
mixed together).
Blue-gray indicates that
this audio item has
been rendered. Green indicates that
this audio item requires
sample rate conversion.
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.
Description Bar color
Indicates audio items that require sample rate conversion. Green
Indicates audio items that have been individually rendered. Blue-gray
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.
The Rendering Process
When you are ready to render, you need to choose render quality settings for your
sequence and decide which segments you want to render.
