the voice over feature allows you to play a portion of a timeline while recording a new track of audio. any real-time transitions and video effects will play back, as well as four tracks of audio of your choice.
1. mark an in point and an out point on the timeline. you can do this by using the playhead to move to the point you would like playback to begin at and pressing the hotkey i, and then moving the playhead to the point you would like to finish playback and pressing the hotkey o. (marking in and out on the timeline is covered in more detail in chapter 8). if you do not mark an in and an out point, playback will begin at the start of the project and run until you stop it. if only an in marker is determined playback begins from the in marker. if only an out marker is determined playback begins at the start of the project but ends at the out marker.
2. select output ] voice over from the main menu. a window opens:

3. choose a save destination for the wav file you will be creating. the default save location is the audio folder in your project management settings. or you can press the browse button to open a window and choose a new location.
4. choose a name for your voice over file.
5. select the audio input source for recording.
6. set your audio data rate, stereo/mono, and sample rate.
7. choose which four audio tracks you would like to monitor while recording the voice over track.
8. press start to begin playing the timeline from the in point and begin recording incoming audio.
if you press stop and then start again, playback and recording will begin again from the in point on the timeline, overwriting your previously recorded audio.
if you press stop and done before the out point has been reached, your audio file will be shorter than the duration from in to out on the timeline.
9. when you have finished recording your voice over track, press the done button. the voice over window closes. the new stereo audio tracks are placed on the timeline, lined up to the marked in point. they are placed on the uppermost available adjoining audio tracks.
if no tracks are available, dpsvelocity alerts you to the problem. it is up to you to add a pair of audio tracks to your timeline and add the wav file from the gallery to the timeline.
