The two options I know about doing this are ....
Just start the whole Multicam Edit again OR Start a new Multicam Edit from a point on the timeline before the first Multicam Edit finished, then "join" the two bits together.
What I would love to know is....
Is there another way to just "pop" the original Multicam Edit back into the Multicam Plugin and continue to edit and not lose all the indiviual edits?
Cheers I just want to edit and make pictures, walk my dog and go fishing.
