A Reddit user demonstrates running MiniMax H3 image-to-video generation locally on an RTX 3090 (24GB) using ComfyUI and Q4 GGUF quantization. Using a digital sketch as the first frame, the user prompted a timed metamorphosis where the drawing transforms into a photorealistic office with a plane passing by. Generating the 5-second clip took about 10 minutes.
