What you will get

A crackling ring of energy in your colour tearing open in your dark setting, sparks and debris swirling inward, a strange glowing landscape inside and a small silhouette stepping toward it as the camera pushes in from behind.

Why it works

Portal scenes need scale and pull. The prompt asks for debris sucked inward, which shows the force without explaining it, and a lone small figure to show how big the opening is. Seeing a strange landscape inside gives the viewer a reason to wonder where it leads, and the slow push from behind the figure puts you in their place, with a deep bass hum adding tension.

Common mistake

The figure is too large and blocks the portal.

Fix: As the tip says, keep the figure small in the frame, ideally in the lower third, so the portal looks huge.

Also watch for
  • The portal looks like a flat glowing disc. Ask for depth inside it: a landscape stretching far away, with its own light and sky.
  • The debris flies in random directions. Ask for sparks and debris pulled inward, spiralling toward the centre of the ring.
Try a variation: closing behind them

Add a second clip where the figure steps through and the portal snaps shut, leaving the warehouse dark and a few sparks falling.

Still not right? Add this and run it again
