I made a movie last week but the opening and closing clips were not what I wanted. Yesterday I shot the opening and closing clips again. I don't know how to get both movies on the timeline so that I can edit them together.
(Assuming you're using version 11) Just use Add Media to add the new clips to your project and then replace your old on the timeline. Just basic stuff.
If there is a part of this process that isn't clear, you can as a more specific question.
Otherwise, you may want to check out my free 8 part Basic Training tutorials.
I'm going to go through your Basic Training tutorials this week. I need the basic stuff.
