| # LTX2 Distilled Refine LoRA | |
| This repo contains the distilled LoRA used for LTX-2 two-stage refinement. | |
| FastVideo loads it only when `ltx2_refine_enabled=True` (or the equivalent refine | |
| flags). The base model repo can reference this LoRA via | |
| `fastvideo_refine_lora_path` in `model_index.json`, so users do not need to pass | |
| the LoRA path manually. | |
| ## Contents | |
| - `ltx-2-19b-distilled-lora-384.safetensors` — distilled LoRA weights for the | |
| stage-2 refine denoising pass. | |
| ## Usage (FastVideo) | |
| Use a distilled LTX-2 diffusers repo that includes | |
| `fastvideo_refine_lora_path="FastVideo/LTX2-Distilled-LoRA"` in its | |
| `model_index.json`. Then enable refinement: | |
| ```python | |
| from fastvideo import VideoGenerator | |
| generator = VideoGenerator.from_pretrained( | |
| "FastVideo/LTX2-Distilled-Diffusers", | |
| ltx2_refine_enabled=True, | |
| ) | |
| ``` | |
| FastVideo will download this LoRA repo automatically only when refinement is | |
| enabled. | |
