The Door Loop" is a single continuous one-take AI film following a lone traveler who walks through a series of doorways, each one instantly transforming reality — from a dim hallway into a bioluminescent forest, a submerged cathedral, and a golden desert with impossible floating rock formations — before the final door reveals they've walked right back into where they started. Built entirely with Seedance 2.5's native 30-second single-pass generation, the film uses one unbroken camera move to blur the line between where the journey ends and begins.
