Generating HDR Video from SDR Video

Daisuke Iso, David B. Lindell, Feiran Li, Francesco Banterle, Jiacheng Li, Karanpreet Raja, Kiriakos N. Kutulakos, SaiKiran Tedla, Trevor Canham

Large generative video models can synthesize HDR sequences from casual SDR video by first predicting bracketed linear exposures and then merging them.

✓ Portable graph bundle live · download bundle · merged state

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

our approach enables robust HDR conversion for in-the-wild examples from casual consumer videos and even iconic films.

C2weakest assumption

That large-scale generative video models can reliably predict accurate exposure-bracketed linear SDR sequences from a single nonlinear SDR input without introducing artifacts or inconsistencies.

C3one line summary

A multi-exposure video model predicts bracketed linear SDR sequences from single nonlinear SDR input, which a merging model combines into HDR video preserving shadow and highlight detail.
