What you get back
A finished MP4 in the shape you chose, such as 9:16 for Reels. Edits keeps every run, so closing the tab does not lose the render. To revise, name the shot or title and what should change.
Make a 20-second vertical Reel from my clips like the reference: same cut speed, captions in the same place, cuts on the beat. Open on the sunset shot.
