In my script I change backgrounds in this order to simulate someone following another person.
EXT. CITY HIGHWAY LOOP - DAY with CAR ANGLE VINTAGE
EXT. CITY HIGHWAY LOOP - DAY with CAR SIDE BROWN
EXT. CITY HIGHWAY LOOP - DAY with CAR ANGLE VINTAGE
EXT. CITY HIGHWAY LOOP - DAY with CAR SIDE BROWN
A random outdoor scene
I tried using the curtain transition to smooth it out but that made it worse.
You need a pause or narration after each background other wise it will just skip them all. A transition will literally open the scene then skip to the next one without a pause which is why you’re getting that jumpy/cut between them. I would recommend putting @pause for S without a transition for this kind of scene
(S = number of seconds)
