280+ generations to make Superman vs Saitama: MiniMax H3 workflow lessons
Automatic-Building84 · reddit · 2026-10-08
A creator finished a Superman vs Saitama trailer using MiniMax H3 after 280+ generations, open-sourcing a custom workflow interface with qwen image 2.1 integrated for references and per-generation setting tracking.
Key takeaways:
- Storyboards were the biggest surprise: the intro Superman shot alone took 29 retries; best results came from a storyboard first, then adding character/style refs separately. First-frame/end-frame came second, most stable for continuous single-shot motion.
- LoRAs: Combat V2 for fast action (with Original H3 render, ≥20 steps), Realism for slower shots; stacking multiple LoRAs mostly caused hallucinations.
- Motion Cache sometimes beat Original, but Original stayed best for heavy action and fast pacing.
- Editing mindset: no magical one-shot workflow — the final fight was assembled from 10 successful 15-second generations.
Ran on an RTX 5090 32GB with custom INT8 optimizations (4 min drafts) plus low-vram attention and feed-forward chunking.
