How can I create consecutive Firefly video clips with visual continuity?

How can I create several consecutive video clips in Adobe Firefly while preserving visual continuity between them?

I create music videos by combining multiple short clips generated with the Adobe Firefly Video Model. What is the recommended workflow for keeping the same character, location, lighting, colour palette and direction of camera movement across consecutive generations?

Should I use the final frame of one clip as the starting frame of the next clip? Is there a way to preserve the same seed, character reference or scene reference between video generations? How can I avoid visible jumps or changes in facial features, clothing and background at the transition point?
