Hi Bruce…
You likely did you mixing in track mode. That’s why the keyframes don’t ripple with the clips.
there are a couple of ways to deal with this.
option 1
Sometimes a quick fix for this is to use nesting.
1) Make a new blank sequence
2) Then in the project panel drag your previously edited seqeunce onto the new sequence timeline.
3) Now you can deal with it like a clip and trim it out to set up the the leader the way you want. The fully editable mix still exists within that sequence and will ripple accordingly as you trim and set up your leader.
The downside to this is that you multi track mix will only be a stereo pair on this timeline.
if that’s not acceptable then you will have try option 2
forget the nesting and focus on your main sequence.
You’ll have to use the Pen tool in the timeline and click and drag to marquee select all the keyframes in the track.
This will turn them yellow.
Then click on 1 of the hightlighted keyframes and start to drag left or right (earlier or later). There should be a time readout that tells you how far in time you are moving them.
Also, if you then tap the SHIFT key during the drag, it should constrain the move (either horizontally or vertically depending on the way you are dragging at the time) this will allow you to move in time with out adjusting level by accident (or adjust level without shifting time by accident accordingly)
You’ll have to repeat this for every track individually.
