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.
