LiuGenAI opens beta for SDR-to-HDR video model LTX
LiuGenAI has released LTX HDR (LTX-2.3-22b-IC-LoRA-HDR) in beta, an AI video model designed to transform standard dynamic range (SDR) video into high dynamic range (HDR) with improved color grading capabilities. This development addresses limitations of previous 8-bit SDR AI models, supporting professional coloring workflows with SDR input to EXR output and offering availability via API, ComfyUI, and as an open-source IC-LoRA on HuggingFace.
Key Takeaways
- LTX HDR is in beta and targets SDR-to-HDR conversion for video workflows.
- The model supports SDR input to EXR output, aimed at professional coloring workflows.
- API access is available for V2V only, alongside ComfyUI support.
- An open-source IC-LoRA version is posted on HuggingFace at Lightricks/LTX-2.3-22b-IC-LoRA-HDR.
- The description says prior AI video models were limited to 8-bit SDR output.
Why It Matters
LTX HDR brings HDR conversion into an AI video pipeline that is explicitly built for professional coloring workflows, with SDR input and EXR output. That matters because the source frames the problem as dynamic range, not resolution, and says earlier AI video models were limited to 8-bit SDR output, which made grading and compositing harder. The distribution path also matters: API, ComfyUI, and HuggingFace give the same beta multiple entry points. What to watch next is whether LiuGenAI expands beyond V2V-only API access and what files or updates appear on the Lightricks HuggingFace release.
