Have a 6 mins video of an artist playing keyboards. I want to place the titles on the screen as he begins each tune. I can place the first one, which is set on Track 3. However, when I reach the point to place the second title, I bring up the title editor, change the title from the previous one (which is still shown on the editor screen) to the new title, but this erases the first title and replaces it with the second one...which is wrong title for the tune being played. How do I 'lock' Title 1 so that it is not replaced by Title 2?
