Adding audio suddenly creating video gap

I'm working on a slide show and it was going really well until today. The video is finished, with transitions, effects, etc., and I've been adding audio over the past couple of days. Today, I added a couple of songs and they did fine, then I added another one and it caused a gap in the video. When I go to the video line and right-click the gap, the ''Delete and Close Gap'' is greyed out so I can't use it. The gap doesn't ''match'' the audio--it starts about halfway through the audio and then ends where the audio ends. This is really frustrating, as I can't see anything different about this section of the project from the rest of it. (same file types, etc.) Can anyone tell me why this is happening and how I can correct it? Thanks!

You're seeing the program's ripple editing feature.



To override it, hold down the Ctrl key as you add your new clips.

Steve--Thanks so much--of course that worked like a charm! :) I can always count on you to know right away what I'm doing wrong!! I do have one more question--why did the ripple feature only kick in towards the end? I had 1 hour and 6 minutes of audio tracks that didn't cause any of the ripples, then it seemed to happen out of nowhere. I don't *think* I was doing anything differently up to that point. I'm mystified! But also very, very thankful to know the cure--I'll be doing some last minute touch-ups and then I'll be ready to burn this one! Yahoooooo!!!!! :) Take care, Tina

It's always been there, Tina. (It's what makes your clips snap left as you add them to the timeline.) You just didn't notice it because you weren't placing clips that the program thought were inserts until the end.



Lots of great tips like that in my book, of course. ;)
