v2.0 Adds Ref Mods, a highly organized Ref/Media Manager, and makes everything smoother and easier to use. Make sure to update the latent upscale file to the new one.

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!

v2.0 Usage Guide:

Shortfilm entirely made using this workflow:

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.

.: Latent Upscaler

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

- NEW Latent Upscale Model: https://huggingface.co/LBH-123-AI/Minimax_h3_latent_Upscaler/blob/main/minimax_h3_latent_upscaler_3d_conv_v1/minimax_h3_latent_upscaler_3d_conv_v1_fp16.safetensors

(put into /latent_upscale_models/ folder and, since 9/17, this needs to be reselected in the WF's selection for latent upscaler choice due to the author renaming the file)

.: Prompt IDE

.: Resources Loader (MiniMaxH3-PromptBuilder)

https://github.com/Adudeguyman/ComfyUI-Fantastic-MiniMaxH3-PromptBuilder

.: RefMods

https://github.com/Luisacaotica/ComfyUI-MiniMaxH3Mod

.: Turbo LoRA

https://huggingface.co/silveroxides/MiniMax-H3_tests/blob/main/minimax_h3_fl2v_turbo_silver_dareties_comfy_pruned_v1.safetensors

This particular Turbo LoRA is my favorite. I recommend 6-8 steps if at 1.0 strength, or 8-10 steps if using at 0.6-0.8 strength. If you're upscaling, 6 first pass + 3 upscale pass works well.

.: 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).
