Subtitles of the Movie

In this movie, I demonstrate some techniques for working with audio in the Mixer window. Using the audio mixer window you can apply changes to audio tracks as a sequence plays back. You can instantly hear the results of any changes you make. You can control the volume, pan, and mute settings of a track, or its sends. You can control all Effect options for track effects including the Bypass setting. The Audio Mixer records the changes as track keyframes in the audio tracks if you choose. It doesn't make changes to the source clip. Let me demonstrate this by playing back this sequence and then adjusting the volume. Notice that each of these tracks here corresponds to a track in my Timeline, so in Track number 1, or I should say Audio Track number 1, I have this clip and I'm going to adjust the volume. Notice that as it's playing back you'll hear these changes. So I've turned the volume all the way down; let's turn it back up gradually. So there you saw, in action there, how you can control various settings here in the Mixer and hear it back in real time. Now you can also use the controls in each Audio Mixer channel to record changes to its corresponding audio track. That includes the pan and the volume as well as any audio effects that you add here to the five audio effects channels. What will happen there is you record those changes so that the next time this sequence plays back those changes are built into the playback. So to set this up, first in the Timeline panel, or the Audio Mixer panel, set the Current Time Indicator; where you want to start your recordings. You can see that I actually did a previous recording here. Here are keyframes that were set up by changing the volume while playing back this clip. I did that in the beginning part of the clip and you can see those keyframes there. Notice there are a lot of keyframes in this section of the sequence where I was changing the volume. Fading it up. Let's go ahead and do another recording session, so I'll move my Current Time Indicator to this position. I can also use this control up here in the upper left-hand corner of the Audio Mixer, notice my Current Time Indicator is moving to fine-tune that position. Next in the audio mixer, choose an automation mode from the Automation Mode menu at the top of each track that you want to change. To record changes, choose a mode other than Off or Read. I'm going to choose Write, and that'll actually write the changes to my sequence right here. Let's move this up a little bit where I don't have any other keyframes already set up. So now I'm ready to go with this set to right, I'm going to play back this sequence, either here in the Timeline window, or here at the bottom of the audio mixer, and then I'm going to adjust the volume slider and those changes will be recorded here in my Timeline. So I've turned the volume down; let's turn it up a little bit. Let me turn it back down again, and let's stop the playback. Now if we go back and look at our sequence, notice that there are a bunch of keyframes there indicating the volume changes that I've just applied. There they are right there. And if I play this back the volume will play back exactly as I set it up with the slider. Let's play this back and listen. And the volume's down to zero. And then it stays there at zero and goes back up a little bit at the end. So you can see that this is a very handy way for doing real time mixing, especially if you have more than one audio track. I only have one audio track here, but imagine if you have four or five and you want to adjust the levels in real time; this is a great technique for doing that. Now you may not see these keyframes after you do your recording. You'll hear the changes in the audio but you want to make sure that the Hide Keyframes option at the bottom here of your Timeline is not enabled and that you have selected the Show Track Keyframes option, so that'll show those track keyframes for you. And one more technique; you can also, after you've laid down those keyframes, modify those keyframes to fine-tune your audio adjustments here. Notice that I can adjust these. Let's go ahead and zoom in a little bit, and notice that I'm adjusting these keyframes to give me maybe a smoother fade-in on the volume there. Now, at this point it will be instructive to understand exactly how Adobe Premier Pro CS3 processes the audio settings that I've been describing in the last several movies, so let me now move on to the next movie entitled Conforming Audio. And that will conclude this quick overview of working with audio in Premier Pro CS3. In this section of the tutorial you learned the importance of planning your audio workflow. You've learned about audio clips, tracks, and channels, and how to adjust the gains and volume levels of your audio clips and audio tracks. You've learned how to create audio split edits and how to apply audio effects to tracks. You've learned how to work with the Audio Mixer to perform real time recording. Let me now move on to the next section of the tutorial, Exporting Movies, where you'll learn about export formats, more about compression, audio and video compression; you'll learn how to export to DVD, Blue Ray Disk or CD ROMs, also how to export for the Web, and export to Flash. You'll learn a lot about the Export Movie Settings, and the section will conclude with a review of the Adobe Media Encoder.
