Let us see if the following will work for you
Video 2 - Video Clip
Audio 2 - No Content
Video 1 - Video Clip
Audio 1 - No Content
Narration Track - Narration Clip
Soundtrack - Music
1. Highlight/select Video Track 1 content
2. Using the scissors tool in the stem of the Timeline Indicator, make two cuts in Video Clip on Video Track 1 in order to create the 20 seconds segment for removal;
3. Right click only the 20 seconds segment on Video Track 1, and, from the pop up, select Delete. There should be a 20 seconds gap where the segment had been...no ripple effect.
4. Now as you hold down the Ctrl key of the computer main keyboard, add your new file into the gap created by the deletion of the segment, using the order
a. drag replacement into gap with Ctrl key held down
b.when the clip is in place, only then release the Ctrl key
Did that work for you? If not, please tell us what happened. I road tested this, so it should work.
Looking forward to your results.
Thank you.
