Direct the whole production, not just the clip.

What's new
What changes with 2.5
50 references, one scene
Load the character sheet, the product shots, the location, the voice. Seedance 2.5 uses all of it to anchor every shot.
30 seconds, natively
Pick any length from 4 to 30s, or let Smart Duration choose. No stitching short clips together.
Edit and extend inside the model
Change a shot, add the next one, and chain clips with Return Last Frame. Export in .mov when the edit continues somewhere else.
Direct every shot
Set lens, zoom, focus, and depth of field shot by shot. Block camera moves with 3D Motion and feed them in as a motion reference.
