LTX 2.3 Video Upscaling is INSANE — IC-LoRA Upscale Workflow in ComfyUI

In this video, I'll show you how to upscale AI-generated videos to cinematic quality using LTX 2.3 and the IC-LoRA Upscale by Zlikwid inside ComfyUI — with RTX-powered upscaling for insane detail enhancement. This workflow takes your existing videos and transforms them into high-resolution, sharp, cinematic output using depth, canny, and pose annotation as reference guides.
