to adjust the volume that you use to set other effect options. It’s often simpler to adjust the Volume effect in a Timeline panel.
You control track output levels in the Audio Mixer or a Timeline panel. Although you control track levels primarily through the Audio Mixer, you can
also do so using audio track keyframes in a Timeline panel. Because track keyframes represent mixer automation settings, they affect output only
if automation is set to Read, Touch, or Latch.
You can adjust the gain for an entire sequence with the Normalize Master Track command.
Normalize one or more clips
1. Do one of the following:
You can adjust the gain of a master clip so that all instances of the clip added to a Timeline panel have the same gain level. Select the
master clip in the Project panel.
To adjust the gain of just one instance of a master clip already in a sequence, select the clip in a Timeline panel.
To adjust the gain of more than one master clip or clip instance, select the clips in a Project panel or sequence. In a sequence, Shift-
click the clips to select them. In a Project panel, Shift-click to select contiguous clips, or Ctrl-click (Windows) or Command-click (Mac
OS) to select non-contiguous clips.
2. Choose Clip > Audio Options > Audio Gain.
The Audio Gain dialog box opens and Premiere Pro automatically calculates the peak amplitude of the selected clips, reporting the
calculated value in the Peak Amplitude field. Once calculated, this value is stored for the selection. You can use this value as a guide for the
amount to adjust gain.
3. Select one of the following, set its value, and then click OK:
Set Gain To The default value is 0.0 dB. This option allows the user to set gain to a specific value. This value is always updated to the
current gain, even when the option is not selected and the value appears dimmed. For example, when the second option, Adjust Gain By, is
used to adjust the gain by -1 dB, the Set Gain To value would also update to show the resulting gain level. When the Audio Gain dialog is
opened for selected clips that have already had their gain adjusted, the current gain value is displayed in this field.
Adjust Gain By The default value is 0.0 dB. This option allows the user to adjust gain by + or - dB. Entering a value other than zero in this
field automatically updates the Set Gain To dB value to reflect the actual gain value applied to the clip.
Normalize Max Peak To The default value is 0.0 dB. Users can set this to any value below 0.0 dB. For example, a user may want to allow
for headroom and set this to -3 dB. This normalization option adjusts the maximum peak amplitude in the selected clips to the user-specified
value. For example, a clip with a peak amplitude of -6 dB will have its gain adjusted by +6 dB if Normalize Max Peak To is set to 0.0 dB. For
a multiple-clip selection, the clip with the maximum peak will be adjusted to the user-specified value, while the other clips will be adjusted by
the same amount, preserving their relative gain differences. For example, assume clip one has a peak of -6 dB, and clip two has a peak of -
3 dB. Since clip two has the greater peak value, it will be adjusted by +3 dB to boost it to the user-specified gain of 0.0 dB, while clip one
also will be adjusted by +3 dB, boosting it to -3 dB, and preserving the gain offset between the two clips in the selection.
Normalize All Peaks To The default value is 0.0 dB. Users can set this to any value below 0.0 dB. For example, a user may want to allow
for headroom and set this to -3 dB. This normalization option adjusts the peak amplitude in the selected clips to the user-specified value.
For example, a single clip with a peak amplitude of -6 dB will have its gain adjusted by +6 dB if Normalize All Peaks To is set to 0.0 dB. For
a multiple-clip selection, each clip in the selection would have its gain adjusted by amounts necessary to boost them all to 0.0 dB.
Normalize the Master track
You can set the peak volume level for the master track of a sequence. Premiere Pro automatically adjusts the fader for the whole master track
upward or downward. The loudest sound in the track achieves the value specified. Premiere Pro scales any keyframes on the master track upward
or downward, in proportion to the adjustment made in overall volume.
Note: Adobe Premiere Pro does not allow a volume adjustment that would raise the peak higher than 0 dB.
1. Select the sequence you want to normalize.
2. Select Sequence > Normalize Master Track.
3. In the Normalize Track dialog box, type an amplitude value in the dB field.
4. Click OK.
Adjust track volume with keyframes
You can adjust the volume level of a whole clip or track, or have the volume change over time using the rubber band in an audio track of a
Timeline panel.
1. Expand the audio track view by clicking the triangle next to the audio track name.
2. In the audio track header, click the Show Keyframes button , and choose one of the following from the menu:
Show Clip Keyframes Lets you animate audio effects for a clip, including Volume Level.
