# 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.

## Model Family

- `minimax`

## Status

- `imported-only`

## 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.
