MiniMax H3 + Ultimate Upscale Low 8Gb Vram Friendly
I rendered 1280×736 videos up to 15 seconds with an 8gb vram 4060 card even while browsing the net (no freezes).
Turbo is already in the default checkpoint — do not add speed LoRA.
Or use your favorite model of choice with speed lora if you prefer!
Detailed settings are in the workflow but here is a Low Vram rundown:
stage 1 use 0.3–0.4 MP → stage 2 use 0.9 MP (1280×736), tiles 512×384, upscale denoise 0.18.
Saves original + upscaled video.

NOTE: IF YOU GET MISSING LORA LOADER ERROR
I uploaded another version (No_Lora) with no custom lora plugins, just use that version. If you need Lora that connect them the standard way.

Hello, what is the "OptionalLoraLoaderModelOnly" node missing?
+++
I uploaded another file on this model page which should fix your issue. The file is optional_lora_loader.py but I had to zip it because civit would not allow me to up py files. Simply unizip then:
1. Put optional_lora_loader.py in ComfyUI/custom_nodes/
2. Restart ComfyUI
3. Reload the workflow
This should fix it! Let me know.
@Wilderness_19 It doesn't seem to be working; it isn't detecting it :/
@Natsu24 Could be a few reasons, depending on your install type, version, and so forth. What I did was created a variant that removes the custom lora node entirely, the no_nora version, should be ready for you on the model page. If you need lora just load them the standard way. Hope it works!
Thank you for your creativity—the workflow is fast and easy, but if possible, could you create another workflow that doesn't include a field for increasing video Upscaler?
Do you mean a version with no upscaler at all, or a disable switch to turn it off?
Thanks for the quick reply. Could you create a "disable" option and also another version to convert images to video? We don't want to bother you—your work is really great.
@loranss666 It works fine with images to video, just plug your starter image into the 'first frame' plug and you will be good to go
Nice workflow. i adopted some part of it and integrated to my own workflow. thanks for brainstorming me.
btw, do you think this upscaler can also integrated to MiniMax H3 Continuum?
great glad it helped. I haven't fooled around with Continuum yet but I plan to soon, I'm sure we can get it working, keep your eyes peeled I'll post the workflow once its ready.
Sir, could u plz re-upload optional_lora_loader.py? I cant find this one, plz.
Civit only lets me upload 2 files so I had to take it down here, but I uploaded it to google drive for ya! Hope it works: https://drive.google.com/file/d/1AdZHkSB3tRTLPFE9BOSgUucHX2Ahy1Br/view?usp=sharing
@Wilderness_19 Thank you, sir!
