Beeble has announced SwitchHDR, a new frontier AI model that reconstructs HDR imagery from conventional SDR video, producing scene-linear 16-bit EXR sequences for professional post-production. Designed for filmmakers, colourists and VFX artists, SwitchHDR is available through the Beeble web application.
Built on Real HDR Data
SDR video captures only a fraction of the dynamic range present in a real scene. Once highlights are clipped or shadow detail is compressed or lost, traditional SDR-to-HDR methods can only redistribute the remaining signal, often introducing banding, noise and other artefacts.
In contrast, SwitchHDR is trained on real HDR footage to reconstruct a plausible HDR representation rather than stretch the existing SDR signal. The result rebuilds highlight and shadow detail, suppresses shadow noise and preserves temporal consistency across entire video sequences.
“Most of the world’s video exists in SDR, yet today’s productions increasingly expect HDR-quality assets,” said Hoon Kim, CEO of Beeble. “SwitchHDR bridges that gap by estimating a scene-linear HDR representation from existing footage, giving filmmakers a practical way to integrate SDR footage into modern HDR production pipelines while maintaining creative control.”
Controlled SDR-to-HDR
Unlike automatic conversion tools, SwitchHDR offers direct artistic control over the process. Users can define highlight and shadow regions using luminance masks and guide the model with separate text prompts. HDR reconstruction is applied only to selected regions, while the remainder of the image is carried through without AI reconstruction.
Output is delivered as scene-linear 16-bit EXR sequences in ACES2065-1 (AP0), enabling integration into professional grading, compositing and VFX pipelines.
SwitchHDR is designed for professional production and post-production workflows, including feature films, commercials, sports production, archival restoration and visual effects. The technology expands Beeble’s suite of AI tools for production and post-production, building on the company’s work in relighting, compositing and virtual production.
