Developer notes

• This graph runs MiniMaxH3ReferenceToVideo.
• It accepts up to 9 reference images, 3 reference videos, and 3 standalone audio references.
• The prompt tags the inputs with <Picture 1>, <Video 1>, and <Audio 1> style references.
• The sampler setup is tuned for reference-heavy prompts.

Our notes

• Most interesting of the three for identity, voice, and scene continuity work.
• Best choice if the goal is a character pack, a reference-sheet workflow, or mixed media control.
• Still very heavy for an RTX 3070 with 8 GB VRAM, so treat it as a serious test target.

Required custom nodes

• Native ComfyUI MiniMax-H3 support

Notes
