SUGARfx Rolling Credits: Adding a second heading in Final Cut Pro
Setup the first set of names as usual with the speed and length as desired (see number 1 in the screen grab)
Duplicate the first setup and enter the new CAST names which may be more or less than the original setup, so the user has to expand or contract the asset in the timeline to get the speed as close to the original speed of the first clip. It should be a trial an error setup that takes a few seconds to match.
The second setup should have the option COMPOSITING enabled so it is transparent and the background below visible.
The last thing is to copy the exact same setup, but this time without any text, and place it underneath so it looks exactly an retains the continuity of color (see number 3 in the screen grab attached)
