Recording Audio Keyframes in Realtime in Final Cut Pro
Recording audio key frames during play back is as simple as turning on a button. You will want to know your audio very well before attempting to perform this operation. You may even want to set some markers to help you know when to raise or lower your levels. If you wish to raise and lower your audio levels while in playing your sequence, the first thing you need to do is open the Audio Mixer from the Tools menu (option + 6). The next step is to turn on the Audio Keyframe Record fnction, by clicking the Record Audio Keyframes (Shift + Apple + K) button in the upper right corner of the Audio Mixer. Place your cursor on the slider of the track you wish to adjust the level, and press the spacebar to start playing your sequence. As your sequence plays drag the slider up and down to the desired levels. Once you stop the playback the audio keyframes will be applied to the track. To apply changes to both channels of audio within the same audio track, you will want to make sure they are a stereo pair. To apply keyframes to all audio tracks at the same time, you will need to nest the tracks together and then apply the keyframes to the nest.
