ComfyUI_ChronoEdit_SM

ChronoEdit: Towards Temporal Reasoning for Image Editing and World Simulation,you can use this node in comfyUI,and Vram >8G

Update

• support upscale lora and fp8 dit，if use 8 step and upscale need step>12,if use upscale only need steps>35
• 支持fp8量化模型和放大lora，两个一起用时最好步数大一点，不用加速时，步数大于35
• 推荐5帧8步lora/ use 5 frames 8 steps lora
• 如果跑29帧要跑50步/ if use 29 frames need 50 steps
