OK, a couple of things.
I'm trying to shift everything over (this includes videos, some name supers, and unlinked audio) so I can insert some music here and there. I can drag the music on to Audio 2 or something, but I still want to scoot everything else over a couple of seconds. Is there an easier way to do this?
Secondly, I want to adjust the audio levels on the music. SO I want it to start off soft, grow louder, then back down until you don't even notice it. How would I do this? Thanks.
Use "Insert" to move clips over exactly the duration of the clip you are inserting
or Select All and drage them over with your mouse.
Use the Mixer to create Audio Level changes
use keyframes in the Audio Volume under the audio clip in the timeline.
And looking at some basic Premiere Video tutorials will be advantageous to you as well.
For the Nudging of multiple Assets, have you tried Selecting them all, and then using the Cursor Keys (arrows) to Nudge, one Frame at a time?
For the ramping up/down of the Audio Volumes, there are several ways to do that. Keyframing the Fixed Effect>Volume (in the Effects Control Panel) will allow one to adjust the Volume up/down over time. If you have never done Keyframing, then I would start with the Help File, as there are a lot of things to learn. Once, however, you have concepts and mechanics down, Keyframes are easy, and so very powerful.
