AI-KSK ComfyUI workflow: MiniMax H3 OpenVDN DMD8 FL2VA.

This workflow is the OpenVDN DMD8 first-last-frame route. It composes the pinned OpenVDN vdn-minimax-h3 model with the DMD8 NFE stage via the MiniMaxH3VDNModelComposer node, runs the FL2VA branch through a VDN execution plan, and saves the result through CreateVideo and SaveVideo. The graph also contains two bypassed duplicate branches from the multi-branch layout; only the active branch produces output.

Main features:
- OpenVDN vdn-minimax-h3 pinned model with stage_dmd_8nfe via the VDN model composer
- VDN execution plan on the FL2VA branch
- First and last frame input plus text prompt
- Qwen3-VL 32B MiniMax text encoder with video and audio VAEs
- MiniMax H3 AV decode to saved MP4 video

Suggested workflow:
Use this route to test OpenVDN DMD8 output on first/last-frame shots. Note that two duplicate branches in the graph are bypassed by design; do not enable them when running the workflow.
