    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!

    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

    - 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)

    .: Pixaroma Node Suite

    .: Prompt IDE

    .: RefMods

    .: Turbo LoRA

    NEW [Kijai's DMAD 4-step - for both FL2VA/REF2VA - 8 steps 1.0 strength recommended] https://huggingface.co/Kijai/MiniMax-H3-experimental/blob/main/loras/minimax_h3_DMAD_4step_full_lora_avg_rank_39_bf16.safetensors

    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.

    If you use ref2va or Singularity, this is great too:

    .: 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).

    Description

    Note: 10/5: fixed LoRA loader so it correctly patches model for regular genning. If you were part of the select few who had trouble with LoRA usage yesterday (10/4), downloaded this updated WF version.

    • Adds the Dialogue / Voice Clone Tool (quickly generate 3x line reads for use in your gens -- super user friendly and easy to toggle on and off without ever unloading h3)

    • Redesigns the workflow (many people said the workflow felt too claustrophobic, so I reorganized and spread things out a bit)

    • Small additions: 1. Adds clickable links instead of notes for all model / node / lora resources, 2. Block/Sparse attention can now be toggled on and off for both 1st pass AND 2nd pass individually, so Stage 1 gens are now faster by default.

    • Small fixes: No more toggles that turn on/off randomly due to rgthree being bugged in current versions of comfyUI.
