MeRoPE stops video generation attention from exploding when cameras move far apart.

When computers generate videos, directing the virtual camera's movement is difficult. Existing systems track the camera with math that breaks down when the camera travels long distances. As the physical distance grows, internal numbers in the model blow up, causing errors. To solve this, researchers built MeRoPE, a new way to track camera positions. It measures the relative angles between viewing lines using rotations that keep math values from growing out of control. It turns real-world travel distances into repeating wave signals and adds a built-in guide for how points shift between views. The researchers found that MeRoPE reliably controls the camera better than earlier methods, matching both the intended turning and traveling movements across wide distances and different lenses.

Why it matters

This helps filmmakers and developers create videos with realistic camera movements that don't glitch. It ensures generated videos match real-world camera paths more accurately, which is crucial for applications like driving simulations or virtual reality.
