MiniMax H3 user reports solid characters but erratic audio and reference control
Alexguitar11 · reddit · 2026-09-20
User Alexguitar11 tested MiniMax H3 in ComfyUI to recreate a Rick and Morty scene and documented the pain points.
- Characters came out mostly right, but audio often goes off-script: after saying the requested lines it adds extra unrequested dialogue, and the author can't find a prompt that constrains it
- Reference-to-video also struggles: when combining three reference assets it arbitrarily picks one instead of blending them
