Minimax H3 SEED HUNTER - Latent Upscaler + Seamless Video Continuation + Speedups + Ref Mods

(10/14) NEWEST COMFYUI 0.40 version sucks. It breaks a lot of workflows. Don't update if you can avoid it. Let them fix their shit.

I just made a Discord finally! Please join to connect with other AI Filmmakers or if you have questions about my workflows/process: https://discord.gg/PGAXv4xq7

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.

(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)

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

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!)

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).
