MiniMax H3 Turbo FP8 I2V

Summary

Same-day MiniMax H3 image-to-video workflow from ewin-reg, covering the first/last-frame path and the model's native audio output.

Developer notes

• The graph runs the MiniMaxH3ImageToVideo node with optional first and last frames.
• It uses the same FP8 / NVFP4 / audio-VAE model stack as the t2v template.
• The workflow keeps the 17k+5 frame rule and exposes the keyframe inputs plainly.

Our notes

• This is the most practically useful of the three templates for identity lock and frame-to-frame control.
• Good fit for reference-driven tests, but still a heavy ask on an RTX 3070 with 8 GB VRAM.
• Worth keeping next to the existing MiniMax first-frame and reference workflows.

Required custom nodes

• Native ComfyUI MiniMax-H3 support

Required models

• minimax_h3_fl2va_pruned_int8_convrot.safetensors
• qwen3vl_32b_minimax_h3_nvfp4_awq.safetensors
• minimax_h3_video_vae_fp16.safetensors
• minimax_h3_audio_vae_fp32.safetensors
• minimax_h3_fl2v_turbo_8step_v1.0_comfyui_bf16.safetensors for the turbo path

Notes

• Best same-day MiniMax H3 import if you want a simple first/last-frame graph.
