Dual-clock sampling: separate video and audio step counts — MiniMax H3 tutorial
Control video and audio sampling separately in ComfyUI and compare it carefully with an acceleration LoRA.
Audience: Advanced users balancing sound quality, sync, and generation speed.
Hardware: An NVIDIA environment capable of running H3 in ComfyUI.
Prerequisites
- The T8 audio-video nodes
- A native H3 workflow
- A fixed audio-video test prompt
Steps
- Install the T8 nodes and run the stable base path first.
- Adjust video and audio steps separately while recording time and sync.
- Add an acceleration LoRA only if needed and compare against the native baseline.
Caveats
- Re-test community speed claims on your own hardware and keep experimental nodes separate from stable ones.
