This workflow combines a character image, a motion video, and a separate new audio track. It is useful for keeping the subject identity and visible performance structure while replacing the original soundtrack with a new voice, music, or sound design direction.

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

Main features:

- MiniMax H3 FL2VA diffusion model with connected video and audio VAE routes
- MiniMaxH3ReferenceToVideo conditioning for character image and motion video
- Independent new audio reference is used instead of the original video soundtrack
- Character identity and performance motion can be controlled as separate inputs
- Connected 9:16 portrait widescreen resolution at the 0.4 megapixel setting
- 20-step simple scheduler with res_multistep sampling
- SaveVideo output for a combined visual and audio result

Suggested workflow:

Use the image to define who appears, the video to define how the subject moves, and the new audio to define the sound track or vocal performance. State clearly that the original audio should not be reused. Keep the motion description concise and test audio timing before expanding the scene.
