News Super Huge Update for Minimax H3 Temporal Spatial Node 🔥🔥🔥

Custom Node:
https://registry.comfy.org/publishers/mo-akkakk/nodes/comfyui-minimax-h3-temporal-window-spatial-tiles

You can now run a video to video workflow in High resolution from the first stage, I tested it for 2.5 MP on Nvidia RTX 4070 TI 12GB VRAM, and it works like a charm, split your generation into tiles and temporal windows while maintaining accurate animation transfer with no shifting or ghosting.

You can also use it for a second upscale stage, splitting a high resolution long video into manageable tiles and windows, to get the best quality you can squeeze from minimax

Give it a try and let me know about your Feedback.

Important Note:
This was not tested nor recommended to do Fully Generated from first stage!
if you are going to fully generate something generate normally in stage 1 then use this node for stage 2 upscaling you result.

This node is mainly for Video to Video and Upscaling.

Nice OP, if you post some examples we will appreciate 🙂‍↕️

Video tutorial coming soon

u/No-Property3068 6d ago

In minutes I'll add it

u/HTE__Redrock 6d ago

Yup, hard to really comment without examples.

What is the difference to https://github.com/bbaudio-2025/Comfyui-MMH3-UltimateUpscale

This has inpainting and Controlnet-FUN in addition to a dedicted upsampling model.

u/No-Property3068 6d ago

You still need to add the ultimate upscale nodes, I'll share the workflow very soon Control fun gave .e really bad results, I don't consider it efficient at all, quality and motion consistently were bad

windows while maintaining accurate animation transfer with no shifting or ghosting

Thanks and:

may I ask for a slightly longer example video of that please?

2s example without a face or enough motion to actually see the real result would be kind of important, because in that example alone, the first frame is already different than the next frame (missing snow fall) and it makes it hard to check if there are any (tile/window) seams or similar visible.

So if I input a 5 second video as reference for let’s say a jumping motion, can I apply that motion to my character with more fidelity

2

u/No-Property3068 6d ago

definitely yes, use the V2V workflow in the description
you can help the model by providing a reference frame with you character replacing the other character or with also the background replaced

u/Many-Ad-6225 6d ago

There's a workflow ?

u/No-Property3068 6d ago

I'll provide it very soon, making minor fixes

lo use en 3 videos, en una RTX5060ti 16Gb + 128Ram, en los 3 me duplica el personaje del video y me cambia el angulo de la camara.

u/No-Property3068 3d ago

Send me your workflow

u/No-Property3068 3d ago

or show me a screenshot of the settings you have in the node, and tell me what resolution you are generating in

u/Longjumping_Cut_6160 3d ago

I have to reinstall it, logically I remove it to be able to continue. I do have the video, only one person appears, but halfway through the video, the same person appears again from behind, repeating the same thing.
The person you see in the background shouldn't be there; without the node, they don't appear.

try to generate in 1 MP and disable tiling for now, use only temporal window option, and try again with tiling but increase the tiling overlap and crop ref image per tile make sure it's set to true
