Learn how the Automation Keyframe Optimization feature in Premiere Pro avoids creating unnecessary keyframes in audio tracks.
Automating audio changes in the Audio Mixer can create more keyframes than necessary in the audio track, causing a degradation in performance. To avoid creating unnecessary keyframes, thereby ensuring both quality interpretation and minimal performance degradation, set the Automation Keyframe Optimization preference. In addition to the other benefits, you can edit individual keyframes much easier if they are assembled less densely in the track.

In the Automation Keyframe Optimization area, select one or both of the following options, and then click OK:
Linear Keyframe Thinning
Creates keyframes only at points that do not have a linear relationship to the start and end keyframes. For example, suppose you are automating a fade from 0 dB to –12 dB. With this option selected, Premiere Pro only creates keyframes at the points that represent an increase in value from the beginning (0 dB) and ending (–12 dB) keyframes. If you do not select this option, Premiere Pro may create several incremental keyframes of identical values between those two points, depending on the speed at which you change the value. This option is selected by default.
Minimum Time Interval Thinning
Creates keyframes only at intervals larger than the value that you specify. Enter a value between 1 and 2000 milliseconds.
