Build a Complete 30-Second Scene
Seedance 2.5 supports standard continuous video generation up to 30 seconds, twice the 15-second maximum of Seedance 2.0. A single scene can move from setup to payoff without being split into a stack of short outputs.
Use that longer canvas for story ads, product demonstrations, character performances, and previsualized camera moves. Write the brief as a sequence: establish the opening, describe what changes through the shot, and state where the action should land.
