About LTX-2.3 Pro (IC-LoRA)

LTX-2.3 Pro (IC-LoRA) fine-tunes an in-context LoRA that transforms one video into another under the guidance of a reference video, such as a depth, pose or edge render. Train it on paired rows of a target video, a reference video with the same frame count, and a caption.

The adapter it produces requires a reference video at inference time. Base LTX-2.3 has no video-conditioning path of its own, so reference-video control is only available through an IC-LoRA. Use the standard LTX-2.3 Pro entry for text-to-video and image-to-video fine-tunes.
