HorizonRelight: Relighting Long-horizon Videos Consistently via Diffusion Transformers

arXiv:2606.29095v1 Announce Type: cross Abstract: Diffusion-based video relighting enables controllable relighting from a single input video, but modern video diffusion backbones are trained on short clips and applied to long-horizon videos through chunked sliding-window inference, often causing temporal discontinuities at chunk boundaries. We address this by reframing long-horizon relighting as \emph{temporally conditioned latent domain translation}. Our framework enforces cross-chunk continuity by propagating target-domain latents across boundaries and makes this behavior learnable using \em

Why this matters
Why now

The proliferation of diffusion models in video generation and editing has highlighted the current limitations in handling long-form content consistently, prompting research into novel architectural solutions.

Why it’s important

This development addresses a key technical hurdle in applying generative AI to longer video sequences, enabling more stable and realistic artistic and practical applications.

What changes

The ability to consistently relight long-horizon videos without temporal discontinuities improves the quality and applicability of AI-driven video content creation and editing workflows.
