One rider. One bike. One

One rider. One bike. One forest. One uninterrupted 30-second take.

I wanted to push Seedance 2.5 beyond a beautiful AI shot and test whether it could maintain character identity, bicycle geometry, environment, physics, and complex camera movement throughout one continuous sequence.

From macro drivetrain tracking and high-speed trail movement to a 360° bullet-time orbit and landing — the goal was simple:

Make the impossible camera feel completely real.

Created with Seedance 2.5 for the #ContraSeedanceChallenge.
