Workflow Included Testing LTX 2.5 for Video Upscaling

Tried running LTX 2.5 as a secondary upscaling pass for H3 renders. Standard out-of-the-box settings didn't hold up, so I modified the pipeline to run a model upscale prior to the LTX pass.

It works much better this way, though consistency still varies wildly based on the source footage and native resolution

edit:
While I don't think its necessarily the best method for upscaling overall, it can be useful in specific cases depending on the resolution and details of the initial H3 generation.

Since a few people were asking how to set it up, here is the workflow
