MiniMax H3 Fastest Workflow | 6GB VRAM 16GB RAM — v3.0 — v1.0 Image To Video (HD)

This MiniMax H3 workflow turns an input image into an HD video, with image cropping and saved video output.

The workflow also lists video-to-video and upscaling among its tasks.

The Load Image + Crop node lets you crop the source image before generation.

The workflow lists these required model files: minimax_h3_audio_vae_fp32.safetensors, minimax_h3_ref2va_pruned_int8_convrot.safetensors, minimax_h3_video_vae_fp16.safetensors, qwen3vl_32b_minimax_h3_nvfp4_awq.safetensors, and taeh3.safetensors.

The workflow lists these required node packs: comfyui_nvidia_rtx_nodes, comfyui-kjnodes, comfyui-spectrum-minimax-h3, and plaguekind-nodes.

Settings guidance: choose 4 steps for speed, 6 for stronger consistency, or 8 for the highest stated quality and face consistency.

The workflow notes say Spectrum is off by default, works in 4-step mode, and can be enabled for experimentation at 8 steps; they also recommend the Step 600 Lighting LoRA.

If you encounter an audio issue, the workflow notes suggest disabling the LoRA.
