Thanks Alan,
The info about 10 vs 11 is helpful.
On the rest, that's helpful too. It kind of tells me I must be off base somehow. I've tried all the copying, cutting, pasting and dragging and none of it works because when I drag a selected part or all of a clip, it doesn't work and when I copy a part and then click to paste it, nothing happens and the cut and the paste and the insert are always grayed out. It makes sense what you're saying about the selecting and cutting or copying or pasting. That's always standard procedure. That's why I'm so frustrated.
Maybe I don't know exactly what the "timeline" is. ???
What I have is 5 clips from one stage show that I converted to .mov files and 6 clips from another that I also converted. Then I imported them into iMovie as 2 new events and I tried doing the editing on each of the events, deleting some frames and trying to copy some from one to the other. That didn't work, so I put both shows (events) together in the updated projects folder and nothing still worked.
I remember when I did this last year, I made it work somehow, but I sure don't get it now. I guess maybe another part that I'm missing is how to get them into a project and then to a finalized movie. None of the pieces seem to fit this time.
I sure appreciate any more help you can give me.
Thanks so much
Fred
