    Preview 139374684

    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.

    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+cu130

    Then 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.

    Description

    • Adds Kijai's Overide Preview as main sampler preview

    • Adds Video/Audio Shift as optional node

    • Changes the Load Image node to a custom node that allows cropping/resizing options easily within comfyUI: https://github.com/obvpm/comfyui-obvpm

    • Fixes a bug or two where efficiency nodes weren't connected correctly

    • Defaults to Kijai's int8 convrot vae now that it works with updated Comfy.

    • Adds 2nd Audio ref (because sometimes you need two voice references, amiright?)
