Two free ComfyUI workflows for MiniMax H3. Each makes a 5 second clip with its own sound from one prompt, in 4 steps instead of 20. The 2-step file is about twice as fast again and is good for trying prompts.
We tested six speed files on the same four prompts, with the same seed, and compared every clip with the slow 20-step version. The video shows which one stayed closest and how long each one takes.
