It was trained with downscaled reference latents by a factor of 2. It is based on the [LTX-2](https://huggingface.co/papers/2601.03233) foundation model. - **Paper:** [AVControl: Efficient Framework for Training Audio-Visual Controls](https://huggingface.co/papers/2603.24793) - **Code:** [GitHub Repository](https://github.com/Lightricks/LTX-2) - **Project Page:** [AVControl project page](https://matanby.github.io/AVControl/) ## What is In-Context LoRA (IC LoRA)? IC LoRA enables conditioning video generation on reference video frames at inference time, allowing fine-grained video-to-video control on top of a text-to-video, base model. It allows also the usage of an initial image for image-to-video, and generate audio-visual output. ## What is Reference Downscale Factor? IC LoRA uses a reference control signal, i.e. a video that is positionally aligned to the generated video and contains the reference for context. To allow for added efficiency, the reference video can be smaller, so it consumes less tokens. The reference downscale factor determines the expected downscaling of the reference video compared to the generated resolution. To signify the expected reference size, the checkpoint name will have a 'ref' denominator followed by the scale relative to the output resolution. ## Model Files `ltx-2.3-22b-ic-lora-union-control-ref0.5.safetensors` ## License See the **LTX-2-community-license** for full terms. ## Model Details - **Base Model:** LTX-2.3-22b Video - **Training Type:** IC LoRA - **Control Type:** Union conditioning - Canny + Depth + Pose - **Reference Downscale Factor:** 2 (reference resolution is 0.5x the output resolution) ### 🔌 Using in ComfyUI 1. Copy the LoRA weights into `models/loras`. 2. Use the official IC-LoRA workflow from the [LTX-2 ComfyUI repository](https://github.com/Lightricks/ComfyUI-LTXVideo/). 3. Make sure...
