Regenerate 2K IC-LoRA Video Upscaler: 3-Step Sampling, More Details, Better Consistency

Turn blurry, low-res AI footage into razor-sharp 2K cinema in just 3 sampling steps! NVIDIA's legendary Regenerate 2K video upscaling technology has officially landed in ComfyUI as an IC LoRA (In-Context LoRA)—and the results are breathtaking. 🔥⚡ Unlike traditional frame upscalers that hallucinate wild artifacts or ruin motion, an In-Context LoRA constantly uses your original video as contextual conditioning, preserving original dynamics, identity, and camera framing with pinpoint accuracy. In this video, we cover: • 🧠 The IC LoRA Secret: How continuous visual context prevents motion drift and hallucination during upscaling. • 🥊 Head-to-Head Showdown: Official 5.6GB Companion Model vs. Kijai’s 200MB Pruned Version (Which one should you download?). • 🏃 Extreme Motion & Angle Stress-Tests: Stress-testing fast basketball dribbles/layups, high-to-low dance angles, and micro-expression hair fixes. • 🛠️ Two Production Workflows: Direct upscaling of existing videos vs. Native MiniMax H3 generation-to-upscale pipelines. • ⚙️ ComfyUI Node Walkthrough: Prepare Draft, Compose Target Latent, custom Euler 3-step Sigmas, and LMS Sharp integration. #runninghub #NVIDIA #Regenerate2K #ICLoRA #ComfyUI #VideoUpscaling #AIUpscale #Kijai #MiniMaxH3 #RunningHub #AIVideo #VideoEnhancement #GenerativeAI #AIFilmmaking #StableDiffusion #LoRA ------------------------------------------------------------------------------------------------------------------------ resource https://huggingface.co/slmonker/Open-H3-Regenerate-2K-IC-ComfyUI https://github.com/slmonker/ComfyUI-OpenH3Regenerate2KIC https://huggingface.co/Kijai/MiniMax-H3-experimental/blob/main/loras/minimax_h3_open_regenerate_2k_ic_lora_avg_rank_21_bf16.safetensors online workflow 1：open_h3_regenerate_2k_ic_video_upscale https://www.runninghub.ai/zh-cn/post/2120694001635463169/?inviteCode=kol02-rh021 2：H3_regen2k_ic_Ref2va_upscale https://www.runninghub.ai/zh-cn/post/2120544675928293377/?inviteCode=kol02-rh021 RunningHub Fan Benefit: Sign up and get 1,000 free compute points. https://www.runninghub.ai/?utm_source=kol02-RH021 workflow and prompt engineering download： https://github.com/amao2001/ganloss-latent-space/tree/main/workflow/2026-11-13%20regenerate%202k%20ic%20lora ------------------------------------------------------------------------------------------------------------------------
