MiniMax H3
This workflow has been replaced with my new MINIMAX SEED HUNTER WORKFLOW: https://civitai.red/models/2881362/minimax-seed-hunter-workflow-optimized-fast-latent-upscaler-speedups
Please use that instead.
Watch the tutorial video on how to build an anime-style short using this workflow:
A no-nonsense high level T2V / I2V / FFLF / REF2V workflow for Minimax H3 with lots of options & togglable quality of life features.
Toggle between the [T2V / I2V / FFLF] model & the [REF2VA] model easily
Added Forced Custom Audio: Lipsyncing to custom dialogue/music is now easy for T2V/I2V/REF2VA!
Temporal Upsampler 2nd Pass Option! [https://github.com/matlowai/ComfyUI-MAINodes]
New Image Loader allows cropping/setting max megapixels directly inside node: https://github.com/obvpm/comfyui-obvpm (Must install via unzipping to custom_nodes folder or through comfy-manager's Install via Git option, it's too new to be on the comfy-manager's index)
Kijai's Preview Override (put https://huggingface.co/Kijai/MiniMax-H3-TAE/blob/main/vae_approx/taeh3.safetensors in /vae_approx/ and set as the custom vae for non-pixelated previews)
Speedup: Sage-Attn + New Sol-Attn [https://github.com/kijai/ComfyUI-SolAttn_triton]
Speedup node: EasyCache / Spectrum [https://github.com/xmarre/ComfyUI-Spectrum-MiniMax-H3]
Turbo LoRA (t2v/i2v but works with ref2va if you don't mind [some] audio degradation)
New (8/11/26) Lightx2v 1.0 release [https://huggingface.co/lightx2v/Minimax-h3-Turbo/tree/main]
Film VFI Frame Interpolation (24 fps -> 48 fps)
Easily togglable reference fields: 4 pictures, 2 audio, 1 video
Use this workflow if you:
Are an AI Filmmaker who values character/scene consistency
Want to be able to use FFLF effectively, seamlessly extend videos, or use character reference sheets.
Want to edit videos, or copy & use motion from reference videos
Want fine-tuned control over your shots visuals and audio.
If you wish to generate simple one-off video clips like Will Smith eating spaghetti, the t2v/i2v model that you can toggle to in this workflow will do that for you.

UPDATE YOUR COMFY CUDA VERSION TO 13.0. If you start comfy and see cu130:
[INFO] pytorch version: 2.13.0+cu130Then you are good to go! But if you are using cu126, then ALL your gens with the best version of Minimax's model (INT8 convrot) will be 2x slower than they should be due to inefficient comfy-kitchen operations! Keep in mind if you update your cuda, you will need to reinstall Sage Attention! Download the correct wheel from here https://wildminder.github.io/AI-windows-whl/
ALL MODEL / NODE LINKS ARE IN THE WORKFLOW NOTES OR EASILY INSTALLABLE THROUGH COMFY-UI MANAGER.
