A beginner shares a detailed pipeline for generating 84 video shots using MiniMax H3 (Ref2VA) on a rented Vast.ai RTX 4080 Super.
Stack & Config:
- Prep: Claude for story breakdown, ChatGPT for character refs.
- Generation: MiniMax H3 Ref2VA via ComfyUI API, using int8convrot and SageAttention, 6-10 steps (3 min/shot).
- Cost: $0.20/hr.
The author scripted batch processing via the ComfyUI API. While the final cut suffered from narrative issues (too much narration), the experiment validated a low-cost workflow, with plans to focus on scriptwriting next.
