FINALLY: Lightricks just did the unthinkable.

 

They just shipped HDR generation for AI video.

 

Highlights hold. Shadows breathe. Footage finally grades.

 

Resolution was never the problem. Dynamic range was. https://x.com/hasantoxr/status/2048174314667790726/video/1

 

 

 

It's called LTX HDR and it generates directly in HDR or converts SDR to EXR.

 

No clipped highlights. No crushed shadows. No grading nightmare.

 

Two paths:

→ HDR generation via API (video-to-video)

→ Open-source SDR-to-HDR upgrade that converts existing 8-bit footage

 

Available via API, ComfyUI, and HuggingFace.

 

 

 

@ltx_model output is scene-linear EXR. Float16. ~20-bit effective range.

 

That's the format DaVinci Resolve, Nuke, Flame, and After Effects are actually built for.

 

Resolution isn't the bottleneck for pipeline-ready AI video.

 

Dynamic range is.

 

 

What this opens up:

 

→ AI footage that holds up in broadcast grading

→ Sits alongside 32-bit CGI and 3D renders without mismatch

→ Displays correctly on HDR LED volumes

→ Moves past previs-only into real finishing work

 

 

Worth being clear: this is a beta.

 

Ships as v0.9 on HuggingFace. Open source. Deployable on-premise.

 

Test it on your own footage before you commit it to a job. But the EXR output is real, and it loads into Resolve and Nuke the way you'd expect.

 

 

Full ComfyUI flow + EXR into DaVinci Resolve walkthrough coming next.
