MiniMax H3 Workflows (T2V, I2V, First-Last-Frame, Ref2V, Lipsync) with SageAttention — v1.1 (faster+upgraded) — v2.2 (Cache=Faster 20%)

This MiniMax H3 ComfyUI workflow set creates videos from text prompts, images, and reference clips, with workflows for text-to-video, image-to-video, first/last-frame, reference-to-video, lipsync, prompt generation, and face refinement.

The archive contains five workflows: Face Refiner V2V, MiniMax H3 Base Prompt generator, MiniMax H3 I2V, MiniMax H3 Ref2V Prompt generator, and MiniMax H3 Ref2V.

The I2V and Ref2V workflows include image or video loading nodes and video-combining nodes, including LoadImage, PixaromaLoadVideo, and VHS_VideoCombine.

The two prompt-generator workflows include text-entry and prompt-generation nodes; Face Refiner V2V is a separate video-refinement workflow.

The description links to MiniMax H3 model files, INT8 and NVFP4 Heretic text encoders, and a ComfyUI build on Hugging Face.

The workflow files name these node packs: comfyui_fearnworksnodes, comfyui-kjnodes, comfyui-pixaroma, comfyui-videohelpersuite, comfyui_steudio, and comfyui-AGSoft.

They also name comfyui-lora-manager, comfy-image-saver, comfyui-easy-use, comfyui-rmbg, rgthree-comfy, and comfyui_nvidia_rtx_nodes.

Model filenames listed across the workflows include face_yolov8m.pt, gemma4_12b_it_uncensored_heretic_int8_convrot.safetensors, minimax_h3_audio_vae_fp32.safetensors, minimax_h3_fl2v_turbo_4step_v1.2_768p_comfyui_bf16.safetensors, minimax_h3_fl2va_int8_convrot.safetensors, minimx

The title names SageAttention, and version v2.2 adds the AGSoft MiniMax H3 Cache Node.

Update notes mention a kitchen attention option, VRAM and RAM cleaning nodes, more Ref2V reference inputs, and an optional Face Refine workflow.
