12 Hours with Open-Source Models Yields Film-Grade Realistic 4K Video
Grinderius · reddit · 2026-10-31
A Redditor showcased a photorealistic video (a lifelike cheah at a waterhole) built entirely from open-source models, calling it the realism ceiling for open models; the uncompressed 4K cut is on YouTube. Workflow: ComfyUI templates, a no-LoRA MiniMax H3 pipeline at 3.3MP / 20 steps, then DLSS5 Enhancer, finished with SeedVR or Nvidia Upscaler. Key tip: input images must be at least 3.3MP.
