A developer shared a complete test of generating a 3-minute AI music video locally using ComfyUI and the official MiniMax T2V node on a single RTX 3090 (24GB).
Generation Parameters:
- Resolution: 0.5 MP
- Steps: 20
- Duration per clip: 15 seconds
- Generation time per clip: 35 minutes
The entire video consists of 12 separate clips spliced together, totaling about 7 hours of GPU computation. The author also shared the extensive prompt engineering used for coherent generation, achieving smooth transitions between scenes through detailed camera language and visual element descriptions. Final editing and scanline effects were done in DaVinci Resolve.
