MiniMax-H3 - Reference to Video Workflow

SupportEverything here is free and stays free — the format spec, the nodes, the workflows, the cartridges, the LoRAs. If it saved you a night of debugging (it contains several hundred of mine), tips keep the 5090 warm:☕ Buy me a coffee on Ko-fi💛 Sponsor on GitHub🔁 Liberapay (recurring)⚡ Or right here: the Civitai tip button on this page sends Buzz directly.Identity from reference images, video and audio instead of a start frame. Point it at photographs of a person, a place, a voice — up to 9 images, 3 videos, 3 soundtracks and 3 standalone audio clips — and the render carries them.Three things you need besides this download. Both of the support questions this pack generated on day one were setup, not bugs, so they are first:The node pack — ComfyUI-H3-Multishot. Install via Git URL, restart, then hard-refresh the browser tab; the frontend caches node definitions and you will otherwise see red nodes. Then run python apply_gguf_arch_patch.py from its folder and restart again. Without that patch, loading any H3 GGUF fails with ValueError: Unexpected architecture type in GGUF file: 'minimax_h3' — ComfyUI-GGUF keeps a hardcoded list of architectures and this one is not on it.A ref2va DiT — curve form (smaller, needs ComfyUI 0.30.0+) or original form. fl2va files will not work in this mode.The text encoder and VAEs — Qwen3-VL encoder, and take the mmproj sidecar with it. Load it with the pack's H3ClipLoaderAny at type = minimax, not with "CLIPLoader (GGUF)" — that node has no minimax type, falls back silently, and dies deep inside a tokenizer with an unrelated-looking JSON error.Naming your references in the promptThis is the part that is not guessable. Reference blocks are labelled in the prompt text, and the labels are 1-based while the input slots are 0-based — so ref_image_0 is . is the woman. is the room she is standing in. She walks to the window in the style of .Ordering is fixed by the node regardless of how you wire it: a
