Full assembled listing films first — then the living-room 8-second clip bake-off as supporting evidence.
All 9 clips assembled (exterior → living → living/dining → kitchen → bedroom → bath → kidsroom → basement → yard). Kidsroom included after retry.
8 clips assembled — kidsroom skipped after Veo failure. Shorter film (58.4s vs Grok 65.6s) because that clip is absent.
Grok has kidsroom (9 clips / 65.6s). Veo skipped the failed kidsroom clip (8 clips / 58.4s). Both films 1920×1080. No quality verdict asserted here — watch both.
Real photo from the Brighton set. Every engine below was asked for a slow forward gimbal glide — nothing in the room moves, photoreal, daylight. Early frames should hold; late frames are where geometry and invent show up.
Early frames hold the room. Late: object drift (ottoman / pillows), camera walk-in, minor invent (e.g. cam). Round table and stairs mostly held.
Early OK. Late HARD invent: round table → live-edge, kitchen peninsula, fluorescent fixture. Geometry worse late than Grok.
fal-ai/ltx-video/image-to-video. Cheapest paid clip, but default ~5s (not full 8s) and 768×512. Quality: see frames / pending Design eye.
fal-ai/minimax/hailuo-02/standard/image-to-video (512P). Requested 6s → got 5.875s. Quality: see frames / pending Design eye.
wavespeed-ai/wan-2.2/i2v-480p-ultra-fast. Full 8s at $0.08 actual — cheapest paid full-length clip in this pass. Quality: see frames / pending Design eye.
