Specifying Audio Keyframe Recording Resolution
Before you start recording keyframes using the Audio Mixer, you must define the
frequency with which Final Cut Pro records level and pan keyframes. Final Cut Pro can
record every subtle movement of an audio fader and panning slider or a reduced
(“thinned”) number of those keyframes.
To choose the resolution for audio keyframe recording:
1 Choose Final Cut Pro > User Preferences.
2 In the Editing tab of the User Preferences window, choose an option from the Record
Audio Keyframes pop-up menu:
 All: Records the maximum number of keyframes possible while you move a track
strip’s fader or panning slider. The end result is an ultra-precise re-creation of the
levels you set using the Audio Mixer. The drawback to this option is that you might
end up with an extremely dense cluster of keyframes in the audio level overlays of
the affected clips that can be difficult to edit later. Unless you are doing very fast,
precise audio mixing, you may want to avoid this option.
 Reduced: Records only a subset of keyframe information created when you move a
track strip’s fader or panning slider. The resulting level or pan overlay in the Timeline
or Viewer is still a fairly accurate reproduction of the levels you set, but the number
of keyframes recorded is much lower than when the All option is chosen.
 Peaks Only: Records only the minimum number of keyframes necessary to
approximate the levels you recorded when moving a track strip’s fader or panning
slider. Keyframes recorded using the Peaks Only option reflect only the highest and
lowest levels that were recorded. This is primarily useful when you want to record a
minimum number of keyframes to edit later in the Timeline or Viewer.
Recording Audio Level and Pan Keyframes
As long as the Record Audio Keyframes button at the top of the Audio Mixer is
selected, level and pan keyframes are recorded whenever a fader or panning slider is
adjusted. Keyframes can be recorded both during playback and pause.
During playback, keyframe recording begins when you position the pointer on a fader
or panning slider and press the mouse button, and continues until you release the
mouse button. The density of recorded keyframes depends on what you specified in
the Record Audio Keyframes pop-up menu in the Editing tab of the User Preferences
window.
Note: Instead of using the mouse to adjust your faders, you can also use a supported
control surface to adjust multiple faders and panning sliders simultaneously.
