AI video generated locally on RTX 3050 in under 7 hours

A user on Reddit shared a detailed process for generating a 60-second AI video locally on a GeForce RTX 3050 with 6GB of VRAM. The video was created using the MiniMax H3 reference-to-video model within ComfyUI, employing a quantized version of the model and the Qwen3-VL text encoder. The process involved using consistent character references, a specific six-section prompt format, and chaining six shots together, each starting from the previous one's frames to maintain continuity. The entire generation, including automation via a Python script and API calls to ComfyUI, took approximately 6 hours and 35 minutes, with the user noting ongoing efforts to improve detail and reduce flicker.
