” Maybe a text layer with just a space typed out below everything”
i think that is the answer, and it’s actually really simple to do in FCP.
Sequence Menu > Add Tracks.
ad a new Video track below all other tracks, (or before base track.. cant remember the terminology)
ANOTHER APPROACH: select all , lock audio tracks, use Option + Up arrow to move all V clips up 1 track.
open the text generator with Control + X
holding OPTION, drag the duration field from the canvass in to the Text generator
(or copy/ paste the duration)
in the text gen, delete the “Sample Text” text, (no need for a space)
edit to V1
done
you *could* shift drag all your other video clips back down, slicing up the empty text generator,
BUT that will not work if you have any transitions into black
it WILL work if you have all cuts to black
(shift drag will keep your clips in sync)
