Working with the Movie's Audio If you were listening a few seconds ago when you opened the Turtles movie in QuickTime, you heard the audio in it. You can choose to have Logic play the movie's audio over the score you're creating, or tell Logic to ignore the movie's audio and just play sound from the Arrange window. (The rest of the tasks in this lesson are for Logic Pro users only.) 1. | Press the spacebar to play the song.
As the SPL moves across the Arrange area, the movie plays. However, you do not hear any sound yet.
| 2. | Press the spacebar to stop playback.
| 3. | Click and hold anywhere on the Movie window, and choose Video/Movie Settings from the menu that appears.
The Song Settings window opens with the Video pane showing. At the bottom of this pane is a Sound Output menu.
| 4. | From the Sound Output menu, choose Internal.
 | 5. | With the Song Settings window still open, press the spacebar to start playback.
As the song plays, you now hear the movie's audio. However, it's much more useful to have the video's audio in the Arrange area, where you can edit it. In the next section you'll add the movie's audio directly to your Logic song using a single step.
NOTE If you have your Video Output set to FireWire, the External Sound Output option sends the movie's sound out to the FireWire display device. For more information on using the FireWire Video Output option, see the sidebar below titled "FireWire Video Display." | 6. | Set the Sound Output menu back to Mute.
| 7. | Close the Song Settings window.

FireWire Video Display If you have a FireWire video camera or video deck attached to your system, you can set Logic to display the video you're scoring on an external video monitor attached to the FireWire camera or video deck. In this situation, the Movie window is disabled in Logic, freeing up valuable screen real estate for other editing windows. To enable a FireWire display, visit the Song Settings window's Video pane, and choose FireWire from the Video Output menu.  If you use the FireWire Video Output setting, you may notice a slight delay, or latency, in the display of your video. In other words, you'll hear sound playing from Logic before you see the corresponding graphics displayed in the monitor. This occurs because it takes time to send that video down the FireWire pipe, making it very hard to accurately score your video. But all is not lost. You can adjust the offset applied to the video playback by visiting Logic's Video Preferences pane. There you will find an adjustment labeled External Video to Song. Use this setting to adjust the playback offset in quarter frames until your video is playing exactly in time with the audio coming out of Logic.

Importing Audio from the Movie Logic provides a great option for importing the movie's audio directly into your song. When you use this option, Logic provides a dialog that lets you choose which of the movie's sound tracks you wish to extract. Logic then converts all of the audio files in the movie to a stereo AIFF at the sampling rate used for your song. 1. | Choose Options > Movies > Extract Audio from Movie.
 The "Choose tracks to export" dialog appears. This movie has only a stereo audio track in it, so the stereo track is displayed and selected by default. However, keep in mind that QuickTime is just a media wrapper. You can have several tracks of audio in the same QuickTime movie. Indeed, a QuickTime movie can also have several tracks of video, interactive sprite tracks, and even effect tracks that apply blurs or ripples to the video. QuickTime movies can be very complex creatures.
MORE INFO To create interactive QuickTime movies, you need a product called LiveStage Professional, by Totally Hip software. 
| 2. | Click the "Choose tracks to export" dialog's OK button.
Logic converts the movie's audio and adds it to the Audio window.
| 3. | Press Cmd-9 to open the Audio window.
There sits the converted movie audio.
| 4. | Drag the movie audio to the track named Audio 2, and drop it at the beginning of bar 1.
 | 5. | Close the Audio window.
