# MiniMax H3 I2V Javawock Pack

## Summary

Same-day `MiniMax H3` first/last-frame image-to-video workflow from the updated `javawock7618` pack. This is the newer I2V graph to keep alongside the older `2608` import.

## Model Family

- `minimax`

## Status

- `imported-only`

## Source

- Workflow pack page: <https://huggingface.co/javawock7618/comfy-MiniMax-H3-workflows>
- Workflow file: <https://huggingface.co/javawock7618/comfy-MiniMax-H3-workflows/raw/main/MiniMax_int8_I2V-javano2609.1.1.json>
- Original publisher: `javawock7618`
- Date imported: `2026-09-03`

## Developer notes

- The source README describes this as the `First-Last-Frame` workflow.
- It keeps the pack's INT8 / Sol-Attn / SLA-Attention / Spectrum stack and the integrated latent upscaler path.
- The bundle also adds Fun ControlNet Union support for V2V-style control-video guidance.

## Our notes

- Best new MiniMax H3 I2V import from today if you want the newer pack version.
- Still a heavy workflow for an `RTX 3070` with `8 GB` VRAM, so this is a test target rather than a casual run.
- Useful comparison point against the older MiniMax H3 and LTX first-frame graphs already in the repo.

## Required custom nodes

- `ComfyUI-SolAttn_triton`
- `ComfyUI-Spectrum-MiniMax-H3`
- `ComfyUI-H3-SLA-Attention`
- `ComfyUI-H3-FaceRefine`
- `ComfyUI MiniMax-H3 Latent Upscaler`
- `ComfyUI-Switchboard`

## Required models

- `Comfy-Org/MiniMax-H3`
- `Kijai/MiniMax-H3-experimental` for the Fun ControlNet Union path
- `lightx2v/Minimax-h3-Turbo` if acceleration is enabled
- `drbaph/MiniMax-H3-Turbo-Lora-ComfyUI` if the optional turbo LoRA path is enabled
- `LBH-123-AI/Minimax_h3_latent_Upscaler` if latent upscaling is enabled

## Notes

- This is the newer same-day I2V graph from the pack, not just a duplicate label.
