Could you build this?
Partial Writing custom ComfyUI node wrappers is simple, but training or fine-tuning diffusion LoRAs (like h3upscale x2) and implementing latent tiled upscaling requires deep generative AI research knowledge and GPU clusters.
What it would actually take: A ComfyUI custom node ecosystem written in Python, interfacing with PyTorch, Diffusers, and tile-based latent blending math. The hard part is training the custom LoRA weights on high-resolution video frames and managing VRAM-constrained tiled diffusion passes without boundary artifacts, requiring specialized diffusion ML engineering and significant compute.
