LTX 2.3 Upscale IC-LoRA
## What it doesThis LoRA is meant for taking a lower-res or soft video and running it through LTX 2.3 as a second pass to get a cleaner, more detailed result.
It is not a normal upscaler. It is a generative refinement LoRA, so the output can change depending on your workflow/settings.
How to use it
The basic idea is:
low-res video → bicubic upscale → run through LTX 2.3 with this LoRA
Before using the LoRA, resize your source video with bicubic scaling to the resolution you want to work at.
Example:
640x360 → bicubic upscale to 1280x720 → LTX 2.3 upscale pass
Then use the bicubic-upscaled video as the input/reference video in your LTX 2.3 IC-LoRA workflow.
Use this prompt:
upscale
That is the prompt this LoRA is meant to use.
Notes
The main checkpoint is:
ltx2.3_upscale_ic-lora_06250.safetensors
Other checkpoints are in:
Other Weights/
Those are just there for testing/comparison.
Results will depend on your source video, resolution, denoise/strength settings, frame count, and workflow.
