Source description
This workflow extends the MiniMax H3 digital human setup to a two-character dialogue scene. It is built for controlled short drama, paired avatars, character interaction, and audio-driven conversation where each speaker needs distinct timing, expression, and visual role separation.
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 dual-character reference-to-video route
Connected MiniMax H3 Ref2VA diffusion model with Qwen3-VL text encoding
Separate character references can define Subject 1 and Subject 2
Scene reference can be used to keep the environment and visual tone consistent
Audio-driven timing supports staged speaker turns and dialogue beats
16:9 widescreen output at the connected 0.9 megapixel resolution route
Final video combine route exports the generated scene as an audio-video result
Suggested workflow:
Assign each input a strict role before generation: one reference for the first character, one for the second character, and an optional scene reference for the environment. In the prompt, define who speaks during each time range and who stays silent. This helps reduce speaker confusion, mouth movement drift, and unwanted duplicate characters.
