    it is crazy. bye bye ltx2.3 for videos under 15 seconds ! Great your prompts generators for minimax h3 structure. Thanks a lot.

    jesus, is that on a 5090? my 5080 shits itself on anything above 9 seconds on other workflows. nvidea really scammed me with that vram.

    @stirner727 I have 5080

    With larryvhr nodes with his turbonlra ema 600 steps ema (8 steps) I'm getting around 5-6 minutes speed generation in 0.8 mp to 15 second and in 1mp to 12 second video length

    stirner727Aug 12, 2026

    @Stefan_Falkok Yeah, I checked it all out, we pretty much have the same setup, so I am very optimistic, got all the missing shit sorted out and will try it in a few. ref2vid + continuation and interpolation is a godsend

    I do not use turbo because the sound is affected. only 20 steps with sage attention, triton and <s>spectrum</s>sol attn. 640 X 1152 upscaled with rtx X3 . I am on linux with a fresh Comfyui 0.30 only for minimax h3.

    @sdktertiaire2 hmmmm. I'm using turbo Lora v4 600 steps ema by Larryvrh, and I like the sound more than with spectrum node

    sdktertiaire2Aug 13, 2026

    @Stefan_Falkok sorry, without spectrum but with sol-attn that i switched on your workflow.

    I didn't get any speed boost at all.

    I keep getting an error that says "Cannot read properties of null (reading 'replace')" and I cannot figure out why. Any ideas?

    It's not showing me where the error is.

    Update comfyui and custom nodes

    Frameboy71Aug 6, 2026

    @Stefan_Falkok Hmmm... my ComfyUI desktop is latest and the custom nodes are correctly installed. Weird.

    It has to be the custom nodes... Minimax works fine on the ComfyUI template.

    @Frameboy71 install my portable comfyiu build , update comfyui and nodes and have fun

    ComfyUI has to be git cloned fresh every few months (ask Gemini, etc. why). A git pull at some point is not enough anymore.

    Install ComfyUI fresh (strongly advice a git clone rather than the portable version). And Minimax H3 will work out of the box. I struggled for a day trying to "fix" whatever was causing the error for me. Then followed two different AI's advice: reinstall ComfyUI clean. The custom_nodes you deed. And it'll instantly work.
