LTX-2.3 Upscale IC Lora is a generative refinement adapter for the LTX Video 2.3 model that turns soft or low-resolution clips into cleaner, more detailed footage. Instead of simply stretching pixels, the LoRA recreates missing image information through a second AI pass. Developer Zlikwid released this tool on Hugging Face for local video workflows, giving users a privacy-friendly way to polish their renders.

A generative second pass, not a normal upscaler

Key Features

Requires bicubic upscaling of source video first.
Uses a simple “upscale” prompt during generation.
Generative refinement adds realistic detail and sharpness.
One primary checkpoint ready for immediate use.
Extra weights folder for testing and comparison.
Output varies with denoise strength and frame settings.
Runs fully on local hardware with no cloud uploads.
Works best for 640x360 to 1280x720 restoration.

If you run LTX Video 2.3 at home and often end up with blurry or noisy results, this LoRA can tighten things up during a second processing pass. Video artists who animate with AI will find it useful for cleaning motion artifacts and boosting apparent resolution. Privacy-minded editors can also refine sensitive footage without sending files to an online service.

Developer notes and realistic expectations

Zlikwid provides the main file as ltx2.3_upscale_ic-lora_06250.safetensors and keeps other weights in a separate folder purely for experimentation. The quality of the output shifts noticeably with your source video, upscale resolution, denoise amount, and frame count, so there is no single best setting. Since this is a finished release, no future changes have been announced, and users are free to integrate the LoRA into their existing LTX workflows as they see fit.
