is there a video upscaling workflow?
How do I upscale an existing video I have using LTX? Do I plug it in "Add IC lora guide" node and then in the workflow after the first generation, use the Latent Upsampling? But can't I do it in the start. Please share a way. Maybe this is obvious so something is not already present but I genuinely want to know. Thank you.
You don't want to upscale using LTX...
You'd be better served by basic upscaling workflows with nodes like SeedVR2 or RTX Video Super Resolution or something like that. Or standalone applications specifically for this, Topaz Video. There are dozens of ways to upscale, but that's not a proper use-case for LTX.
The RTX Video Super Resolution is extremely fast. maybe try that

Its also a workflow there.
Unless you meant to add details etc. There is a workflow for LTX to "upscale" and add details to a low resolution video input, using a looping sampler.
But if its just regular upscale, the RTX or as mentioned SeedVR2 or FlashVSR are great ways... they all work in comfy.
Thank you to all!
