Update to v1.5!

This advanced filmmaker's workflow cleanly and quickly generates 3 low resolution sample preview gens, allowing you to select your favorite to then take to upscale finalization. The workflow has every feature an AI filmmaker could need, and easily produce the highest quality and resolution Minimax is capable of. It comes equipped with all quality of life features, the top known speed ups, and many options, from seamless video continuation to custom audio, to frame interpolation to go from 24 FPS to 48-60. Everything is here!

Quick reminder: 0.5 MP -> 2x upscale = 2.0 MP output. That's 4x the pixels. Most 24 GB or under cards will OOM if you try to gen 12-15 seconds at that resolution! This memory-hog of a model was built around 1.0 MP outputs (768p), after all.

I made this entire short film using this workflow alone!

Some nodes in this workflow are too new to be in the Comfy Registry to be installed automatically with Comfy-Manager! Therefore, they need to be installed manually.

.: Load Image Node

https://github.com/obvpm/comfyui-obvpm (download and unzip into into /custom_nodes/)

.: Latent Upscaler

- Node: https://github.com/LBH-123-AI/Comfyui_Minimax_h3_latent_Upscaler

- Latent Upscale Model: https://huggingface.co/LBH-123-AI/Minimax_h3_latent_Upscaler/blob/main/minimax_h3_latent_upscaler_3d_bf16.safetensors

(put into /latent_upscale_models/ folder)

.: Sparse Attention

https://github.com/Zironic/H3-Optimizations

.: Prompt IDE

https://github.com/ethanfel/ComfyUI-H3-Prompt-IDE

.: Turbo LoRA

https://huggingface.co/lightx2v/Minimax-h3-Turbo/blob/main/minimax_h3_fl2v_turbo_8step_v1.0_768p_comfyui_bf16.safetensors

Lightx2v's recommendation is to use euler/beta, with shift value option turned on at 6.0/3.0.

.: Audio/Video Loader node

https://github.com/WhatDreamsCost/WhatDreamsCost-ComfyUI

.: Kijai's int8 Video VAE (much faster than default!)

https://huggingface.co/Kijai/MiniMax-H3-experimental/blob/main/minimax_h3_video_vae_int8_convrot.safetensors

Everything else should be easily available from the ComfyUI-manager Install Missing Nodes screen!

.: TaeH3 (for Kijai's Model Preview Override):

https://huggingface.co/Kijai/MiniMax-H3-TAE/blob/main/vae_approx/taeh3.safetensors

(note, using Kijai's Model Previewer will slow gens down by 6-16% thereabouts, I have it disabled by default now, but you can turn it on to test for yourself).
