This workflow demonstrates how to drive MiniMax H3 video generation with multiple image anchors placed anywhere along the timeline. The core MiniMaxH3ReferenceToVideo node takes a long-form prompt (via PrimitiveStringMultiline) and up to four reference frames, each with its own timestamp and strength (PrimitiveInt and PrimitiveFloat), to steer motion, framing, and subject continuity at specific moments. ResolutionSelector and ComfyMathExpression set clean, multiple-of-32 dimensions, while RandomNoise provides a seed for reproducibility.
Under the hood, H3 returns video and native stereo audio as model latents. VAEDecode converts the video latents to RGB frames, and VAEDecodeAudio decodes the audio stream. CreateVideo assembles frames at the chosen FPS and muxes the decoded audio; SaveVideo then writes the final file to disk. ComfySwitchNode lets you quickly enable/disable individual reference anchors or the audio path. The workflow is grouped for clarity (User Inputs, Conditioning, Extra Image Guidance Conditioning, Video Settings, Decoding and create video), so you can focus on anchoring key frames to force narrative beats, continue an existing clip, or produce tightly timed social content with synchronized audio.
Advanced nodes like UNETLoader, CLIPLoader, VAELoader, BasicScheduler, SamplerCustomAdvanced, and BasicGuider are included for compatibility and potential extension, but the default H3 path works out of the box. If you want to customize dimensions beyond the presets, remove the ResolutionSelector and drive width/height directly (PrimitiveInt), keeping both divisible by 32 for stable decoding.

Utiliser ce workflow depuis le code
Chaque workflow Comfy est un graphe JSON. Le contenu ci-dessous est ce workflow, exactement comme ComfyUI l’exécute — récupérez-le depuis l’URL, gardez-le dans le contrôle de version, ou chargez-le dans ComfyUI et exécutez-le nœud par nœud.
Exécutez-le depuis TypeScript ou Python avec le Comfy SDK. Le même code cible Comfy Cloud ou un ComfyUI auto-hébergé — seule l’URL de base change.
// Install (beta)
npm i @comfyorg/sdk
