This workflow is a MiniMax H3 audio-driven digital human setup for a single character. It is designed for turning one character reference and one audio track into a direct speaking or performing avatar video, with the audio driving the timing while the prompt defines acting style, camera language, and scene mood.

The workflow uses the MiniMax H3 local ComfyUI graph with the connected model, VAE, encoder, sampler, resolution, and final video output chain shown in the JSON.

Main features:

- MiniMax H3 reference-to-video route for a single speaking subject
- Connected MiniMax H3 Ref2VA diffusion model with Qwen3-VL text encoding
- Video VAE and audio VAE routes are both connected to the generation chain
- Audio input drives speech timing, performance rhythm, and mouth movement
- 16:9 widescreen output at the connected 0.9 megapixel resolution route
- 20-step simple scheduler with res_multistep sampling
- Final video combine route keeps the generated performance and audio together

Suggested workflow:

Use one clean character image or first frame and a clearly recorded audio file. Keep the prompt focused on one subject, visible face, readable lips, emotional tone, and camera framing. For better stability, avoid asking for extra people, large identity changes, or fast scene cuts during the first test.
