New CRePE method enhances camera control in video generation models

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method called Curved Ray Expectation Positional Encoding (CRePE) to improve video generation models. CRePE addresses limitations in existing camera encoding techniques by representing image tokens with depth-aware distributions along unified camera model rays. This approach enhances control over camera parameters, lens types, and orientation, performing well across pinhole, wide-angle, and fisheye lenses. The method integrates seamlessly with frozen video diffusion transformers and can also incorporate external geometry maps for scene-geometry-conditioned generation. AI

IMPACT Enhances control and fidelity in video generation models, potentially improving applications requiring precise camera and scene geometry.

    CRePE: Curved Ray Expectation Positional Encoding for Unified-Camera-Controlled Video Generation

    arXiv:2605.12938v2 Announce Type: replace-cross Abstract: Video world models should predict future appearance in a way that remains consistent with 3D scene structure, camera motion, and lens geometry. Existing attention-level camera encodings, however, either describe each token…
