Would be great if on the left side of the timeline for each track there was a vertical slider to adjust volume/opacity. The problem
with the current way (yellow lines) is you can't be precise with it. I'd like to use the mouse wheel to adjust the volume, that
way I can get just the volume I want. Either allow mouse wheel to adjust the yellow volume line on time line, or
add a slider on the left side.
If you've got a feature request, you should contact Adobe directly with it. This is a user to user forum.
But in the meantime:
* You can adjust volume precisely using a slider or numbers if you select the clip and open the Adjustments panel.
* You can adjust opacity precisely using a slider or numbers if you select the clip and open the Effects Settings panel.
* You can apply settings you've made to one clip to several clips by right-clicking on one clip, selecting Copy, then selecting the other clips, right-clicking and select Paste Effects and Attributes.
