iMovie - how to save editable versions of project
I used iMovie to create a holiday movie with photos and music clips. Started by clicking on File > Open Library > New and naming project as 'Holiday 24'. Completed the movie and, I believe, iMovie saves the project automatically.
Now I wish to replace one of the three music clip and leave the photos and the other remaining music clips unchanged.
How do I do that without having the create another "new" project and starting from scratch?
At the end, aim is to have 2 editable versions - "Holiday 24" and Holiday 24 v1", that I can open.
Thanks in anticipation.
