<p>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.</p><div data-youtube-video><iframe width="640" height="480" allowfullscreen="true" autoplay="false" disablekbcontrols="false" enableiframeapi="false" endtime="0" ivloadpolicy="0" loop="false" modestbranding="false" origin playlist src="https://www.youtube.com/embed/DvTl-QbDzdQ" start="0"></iframe></div>
<p>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.</p>
