Hi,
While I was searching for my problem with FCPX, I found you’ve experienced the same issue.
I cannot ‘insert edit’ the clip just by dragging it. The reply posted below was one way to do it, but doesn’t solve the problem fundamentally.
I wonder, did you solve your problem so that you can now drag the clip and ‘insert’ instead of overwriting? I don’t really want to bond clips as storyline when I’m just starting to make a rough cut.
Hope to hear from you. Thanks!
