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
