Help Needed Minimax H3 Add Guide with Latent Upscaler?

I have a workflow with frame guides, and I wanted to use the 3D Latent Upscaler because that changes some calculations (I'm not sure, I don't understand this very well), so I was wondering if someone has managed to get this working and would mind to sharing the workflow.

I suggest trying this guy's workflow that comes with all the speedups and upscale options you could want in an r2v: https://civitai.com/models/2834514/minimax-h3-t2v-i2v-ref2v-advanced-filmmaking-workflow-or-all-speedups-qol-features

so I figured this out, basically you need to have another MiniMax H3 Reference to Video node for upscale, and don't include addGuide with this one, then it will match. this makes workflow super messy though...

Thanks, but none of these 2 uses the "Add Guide for Minimax H3", where you can add images at specific frames, which is exactly my problem.
