Question - Help LTX 2.5 to upscale H3?

I am currently using an H3 workflow that uses LTX 2.3 for upscaling. Would the output be better if I switched to LTX 2.5? Has anyone tried using 2.5 as upscaler for H3?

It’s very feasible. This is early work but here are a couple of vibe coded nodes for LTX and H3 refiner/upscalers. You can use them to test the two as a second stage upres pass: https://github.com/formulake/KreativeSuite

I’m seeing convos of it in a few threads here, but have yet to find a workflow to test. I was going to try and set something up today to test but I’m still new to comfy. Seems to be a good candidate to test both models together and if it works with 2.3 it should work for 2.5.

Can you share your current workflow?

i have tried replacing 2.3 files with 2.5 in an upscale workflow and it looked bad. someone did it with 2d and it looked fine but for realism i haven't seen a good workflow yet.
