In the Camera Sequencer, you can import audio files for an entire sequence, or import individual audio files to associate with a specific camera shot.
To import audio files for the sequence
The audio is loaded in the Soundtrack area of the Camera Sequencer.
You can drag the audio clip left or right to change when it starts to play relative to the sequence. To change the audio clip duration relative to the sequence, see Adjust the timing of audio in a sequence.
To associate an audio file with a shot
The audio is loaded in the Soundtrack area of the Camera Sequencer and associated with the selected shot.
The duration and position of the audio clip is controlled by the associated shot, so you cannot drag left or right to adjust the position of the audio clip. For example, if the shot starts at frame 1 and ends at 350, the audio clip also starts at frame 1 and ends at frame 350.
To adjust the timing of the audio relative to the shot, see Adjust the timing of audio in a sequence.
