Generating a 3-Minute AI Music Video Locally on a Single RTX 3090 with MiniMax T2V

A developer shared a complete workflow for generating a 3-minute AI music video locally using a single RTX 3090 24GB GPU, ComfyUI, and the official MiniMax text-to-video node.
The video consists of 12 separate 15-second clips, taking roughly 7 hours of total GPU rendering time. Key generation settings include:
- Resolution & Steps: 0.5 MP resolution, 20 steps
- Time per clip: 35 minutes for each 15-second clip
- Post-processing: Edited in DaVinci Resolve with added scanline effects
The creator also detailed the complex prompts used to generate the surreal, psychedelic music video scenes (like floating glowing blue lips and organic crystal tunnels), providing a highly valuable practical case for local AI video generation.
