A Reddit user shares a low-VRAM ComfyUI workflow: generate 0.6MP video with MiniMax H3 Singularity V2 + Pika H3 LoRA in 6 steps, then progressively upscale to 1920×1080 with the Ultimate MiniMax H3 Upscale node and Kijai's Regenerative 2K LoRA at low weight. Total time 1 hour on 6GB VRAM. The trick: generate low-res and let regenerative upscaling recover detail. All LoRAs, custom nodes, workflow file, and video tutorial links included.
