There are several ways to attenuate Audio Volume (or Gain) in PrE. This ARTICLE goes into some detail on each method.
Note: When one uses Audio Mixer, it applies Audio TRACK Keyframes, and NOT Audio CLIP Keyframes. There can be a big difference.
Thanks for the input. Unfortunately, I am still having difficulty. Probably something very simple that I am missing.
To clarify, I have one soundtrack that covers 15 video clips. Audio 1 is the sound from the video clip. I want to reduce/mute the Soundtrack Volume during several of the video clips so that video sound (voices) can be heard.
Here is what I tried for "Your First Choice" and "Your Other Choice".
Put in Timeline display
Click anywhere on the soundtrack - it lights up
Click Edit (between Project and Disk Menus)
Click Video Effects > Audio Effects
Select either Channel Volume or Volume
Click Edit Effects
Click Volume --> Clip Volume Slider and also Fade In and Fade Out icons
Play Soundtrack. Slide Volume Slider full left at beginning of each desired video clip and back to normal volume at end of each video clip.
When replay, reduced Soundtrack volume does not occur as selected.
Put in Timeline display
Click on Soundtrack
Click Audio Tools icon
Select Audio Mixer --> yields five dB sliders
Select Play button
Reduce Soundtrack Level to -oo dB during desired video clips
Pause the presentation
Position the blue slider to before the video clips with reduced Soundtrack volume
Get no reduced volume of Soundtrack on selected video clips.
Thanks for any help you can provide.
Some users have had issues with both of the Fixed Audio Tracks, Soundtrack and Narration, though I thought that might have been fixed in PrE 10.
The workaround is to use one of the "regular" Audio Tracks, that is empty, say Audio Track 2, instead of either the Soundtrack or Narration.
Please give that a try, and report on whether that now works. You can lasso the Clips on Soundtrack, and just drag them all to another regular Audio Track.
I moved the soundtrack to channel 2 and also channel 3 (individually) with same result. I tried reversing the order of Edit and Apply and also tried Saving the change before replaying. Also tried the same effects for Audio 1 which goes with the video. No luck for any of these attempts. I guess I'll have to give up on using the tools and just clip the soundtracks to fit. Sure seems strange that these tools are included in PRE10 when you cannot save the effects.
