Choose the right workflow for text, keyframes, or multimodal references.
Audience: Users seeing H3's multiple ComfyUI workflows for the first time.
Hardware: Follow current ComfyUI and official H3 documentation.
Prerequisites
- A working ComfyUI installation
- H3 model and VAEs
- A known input-media type
Steps
- Use text-to-video when the prompt is the only input.
- Use first, last, or first-and-last frame control for boundaries.
- Use Ref2VA to carry a subject, motion, or voice, with references in the documented order.
Caveats
- Input modes use different weights and wiring; do not merely swap input ports.
