About Avid Media Composer Keyframe Audio
Sometimes when using Avid Media, there are times that audio levels fluctuate in the boundaries of the segment and one adjustment is not enough. You need to able to write the levels up and down within a segment and to do this, you'll need to adjust the key frame and set the levels within a clip, otherwise known as rubber-banding.
With Avid Media Composer Keyframe Audio, you can adjust the keyframes manually or play the sequence and automatically let Avid Media place the keyframes as you move the sliders. If you want to use the manual method, then these are the proper steps to doing it correctly.
Step 1: Finding the "Auto Gain" Option
First, open the "Timeline Fast Menu", then click "Audio Data" and choose "Auto Gain". Then, you can choose the tracks in the Avid Media you want to work on. For example, your sequence contains Audio 1 or Audio2, or A1 or A2, which are the tracks that contain the sound.
Step 2: Troubleshoot the Problem
Put the blue position indicator in the timeline where you want to change audio clips. Then, press "enter" on the media composer keyboard. A keyframe will appear in the timeline. As both A1 and A2 were selected beforehand, keyframes will show up on both tracks at the same. Place the blue position indication in the timeline further along it, and click on the keyframe key again. You'll see that another keyframe will appear. With the mouse, move your pointer to the second keyframe, where you'll notice that the pointer will change into a hand. With the hand, hold and drag down the keyframe vertically onto the timeline, which will result in the creation of volume ramp. Listen to the volume change as you play that particular section in the timeline.
Step 3: Using the Keyframes
Often with stereo track in Avid Media, you would want to make volume ramps on both timelines simultaneously. You can do this simply by selecting both tracks, and then the keyframes you created will show up in both tracks. If you discovered that you placed the keyframe in the wrong place, you can easily adjust your keyframes to make sure your sound will be in sync with the entire sequence. To move the keyframe, you can either hold the "Alt-key" or you can click it with a mouse and drag it towards the desired area.
If you think that the keyframes are not adequate, then you can always place at least 1 or 2 more to fix the problem. Move the additional keyframes down the clip further in the timeline and drag the last keyframe up, which results in an audio dip. If you want to delete a keyframe, move the mouse over the keyframe you want to remove. When the cursor becomes a hand, you can press the "Delete" key on the keyboard. If you have chosen to de-select "Auto Gain" from the "Timeline Fast Menu", you'll discover that the keyframes will disappear, and in their place is a small red keyframe on the clip to indicate that they are still in place.
