this use case for Seedance 2.5 is insane...

someone turned a walkthrough of a half-built construction site into a finished, furnished marketing video

the trick: Seedance 2.5's video-to-video mode. feed it a driving video and it re-skins everything while keeping the motion

here's the setup:

- raw walkthrough filmed on the unfinished site = driving video
- 2 generated stills of the finished space = start and end anchor frames
- camera path, pacing, doors, turns... all pulled straight from the real footage
- building, finishes, people in shot... all pulled from the anchor frames

prompt structure:

"Use [reference video] as driving video. Start with [reference image]. POV, camera follows a real estate agent walking towards a newly completed apartment. He's showing off the place to camera, walking casually up a footpath surrounded by lush landscaping. Camera follows him through the glass doors into a furnished common area, marble floor, oak timber wall panelling. Ends with [reference image]. No transformation, no morphing, no bgm."

that last line is the whole trick. without it, Seedance drifts off your camera path trying to be clever

with it, motion stays locked to what you actually filmed

where it breaks: material detail it never saw, marble veining, panel grain, reflections. fine for a teaser, not a client-facing final

for real estate and architecture marketing this changes the math. you don't need the building finished to shoot the video that sells it, you need 30 seconds of someone walking the path

and Seedance 2.5 does up to 30 seconds in one pass, so that's an actual walkthrough shot, not 6 clips stitched together
