The Spine

One locked wide of the block, chained through TIME — five clips, each generated on the previous clip's final frame (chainFrom). The camera never moves; only time does: empty block → framed → locked-up shell → finished at dusk → lights on. Play each (they loop) and scrub; then check every boundary is seamless. Nothing branches until this chain is approved.

The gamble paid off. The chained time-morph holds: Seedance builds the house on a locked frame without drifting the camera or melting geometry. Boundaries are frame-exact by construction (each link starts on the prior link's last frame). Numbers + every boundary below.

01The five links — play + scrub

1/5

S1 · The Block

frames 145dur 6.04s max cut 0.013travel SSIM 0.76 border-lock SSIM 0.88

Anchor. Camera locked; only the light morphs (mist→clear, cool dawn→warm sun). Validates Seedance holds a locked frame.

2/5

S2 · The Slab → The Frame

frames 145dur 6.04s max cut 0.040travel SSIM 0.48 border-lock SSIM 0.80

THE PROOF. Slab + pine wall frames + roof trusses + scaffolding rise on the locked block; light hardens to midday. No camera drift, no melt. The chained time-morph works.

3/5

S3 · The Shell

frames 145dur 6.04s max cut 0.043travel SSIM 0.48 border-lock SSIM 0.86

Locked-up shell: brick veneer to full height, Colorbond roof on, windows in and dark, scaffolding gone, overcast still light. 'From the street, nothing.' Geometry now fixed.

4/5

S4 · The Light (dusk falls)

frames 145dur 6.04s max cut 0.013travel SSIM 0.76 border-lock SSIM 0.87

Finished: exposed-aggregate driveway, letterbox, native garden beds + buffalo lawn made good; overcast warms and lowers to dusk (pink horizon, deep blue above), windows still dark. Camera locked. Perfect handoff into the close.

5/5

S5 · The Light (lights on — the emergence close)

frames 145dur 6.04s max cut 0.020travel SSIM 0.63 border-lock SSIM 0.55

THE EMERGENCE CLOSE. Generated with an end-frame (the approved dusk-lit target): windows light up room by room, warm gold against deep blue-hour; interiors visible, exterior lights on. Lands on the spine 3/4 locked wide (matches S1-S4), not the target front-on angle — correct for continuity. borderLock low only because the sky colour changed dusk->deep-blue, not camera drift.

02The boundaries — seamless?

Each pair: the left is link N's last frame, the right is link N+1's first frame. They are the same handoff frame, so they should be near-identical — proof the chain has no jump.

Boundary 1 → 2: S1 last frame  |  S2 first frame — should be near-identical (chain is frame-exact by construction)
s1 lasts2 first
Boundary 2 → 3: S2 last frame  |  S3 first frame — should be near-identical (chain is frame-exact by construction)
s2 lasts3 first
Boundary 3 → 4: S3 last frame  |  S4 first frame — should be near-identical (chain is frame-exact by construction)
s3 lasts4 first
Boundary 4 → 5: S4 last frame  |  S5 first frame — should be near-identical (chain is frame-exact by construction)
s4 lasts5 first
