Editing Audio
Specify automated keyframe creation
Automating audio changes in the Audio Mixer can create more keyframes than necessary in the audio track, degrading
performance. To avoid creating unnecessary keyframes, thereby ensuring both quality interpretation and minimal
performance degradation, set the Automation Keyframe Optimization preference. In addition to providing other
benefits, this preference makes editing individual keyframes easier because they are less densely arranged on the
keyframe graph. For information about the Linear Keyframe Thinning and Minimum Time Interval Thinning
options, see "Audio Preferences" on page 16.
1 Choose Edit > Preferences > Audio (Windows) or Premiere Pro > Preferences > Audio (Mac OS).
In the Automation Keyframe Optimizations pane, select Linear Keyframe Thinning, Minimum Time Interval

Panning and balancing

By default, all audio tracks output to the sequence master audio track. However, you can also create submix tracks.
You can output audio from any track to a submix track. You can then out put audio from a submix track to a Master
Track. You can use an audio track as an input for a submix track or for the Master Track. You can use a submix track
as an output for an audio track and as an input for a Master Track. Different tracks in the same sequence can have
different numbers of channels. For example, you can send the output from a monaural audio track to a stereo submix
track, and then send the output from the stereo submix track to a 5.1-channel Master Track.
If the number of channels differs between an input track and its output track, you determine how much each of the
channels in the input track feeds each of the channels in its output track. For example, you can send 80 percent of the
signal from a monaural audio track to the left channel of a stereo submix track, and 20 percent to the right channel.
This is balancing. You balance the audio to a stereo output track with Left/Right Pan dials in the Audio Mixer. You
balance the audio to a 5.1 output track with 5.1 Panner controls in the Audio Mixer.
In the Audio Mixer, a Left/Right Pan dial appears in a track only when you select a stereo track as the output for the
track. A 5.1 Panner control appears in a track only when you select a 5.1-channel track as the output for the track. The
relation between the number of channels in an audio track and the number of channels in the output track (often the
master track) determines whether the pan and balance options are available for an audio track.
Panning is the moving of audio from one output channel to another, over time. For example, if a car drives from the
right side of a video frame to the left, you can pan the channel containing the car audio so that it begins on the right
side of the screen and ends on the left.
Note: If necessary, you can balance a clip by applying the Balance audio effect. Do so only after you determine that track
balancing isn't sufficient.
In the Audio Mixer, the number of level meters in a track indicates the number of channels for that track. The output
track is displayed in the Track Output Assignment menu at the bottom of each track. The following rules determine
whether a track's audio can be panned or balanced in its output track:
• When you output a mono track to a stereo or 5.1 surround track, you can pan it.
• When you output a stereo track to a stereo or 5.1 surround track, you can balance it.
