Improved quality with reduced artifacts.\n2. Support for higher resolution and longer sequences.\n3. Frame and sequence conditioning (beyond the first frame).\n4. Enhanced prompt understanding.\n5. Commercial license availability.\n\n### Technical Updates\n\nSince LTXVideo is now fully supported in the ComfyUI core, we have removed the custom model implementation. Instead, we provide updated workflows to showcase the new features:\n\n1. **Frame Conditioning** – Enables interpolation between given frames.\n2. **Sequence Conditioning** – Allows motion interpolation from a given frame sequence, enabling video extension from the beginning, end, or middle of the original video.\n3. **Prompt Enhancer** – A new node that helps generate prompts optimized for the best model performance.\n   See the [Example Workflows](#example-workflows) section for more details.\n\n### LTXTricks Update\n\nThe LTXTricks code has been integrated into this repository (in the `/tricks` folder) and will be maintained here. The original [repo](https://github.com/logtd/ComfyUI-LTXTricks) is no longer maintained, but all existing workflows should continue to function as expected.\n\n## 22.12.2024\n\nFixed a bug which caused the model to produce artifacts on short negative prompts when using a native CLIP Loader node.\n\n## 19.12.2024 ⭐ Update ⭐\n\n1. Improved model - removes \"strobing texture\" artifacts and generates better motion. Download from [here](https://huggingface.co/Lightricks/LTX-Video/resolve/main/ltx-video-2b-v0.9.1.safetensors).\n2. STG support\n3. Integrated image degradation system for improved motion generation.\n4. Additional initial latent optional input to chain latents for high res generation.\n5. Image captioning in image to video [flow](assets/ltxvideo-i2v.json).\n\n## Installation\n\nInstallation via [ComfyUI-Manager](https://github.com/ltdrdata/ComfyUI-Manager) is preferred. Simply search for `ComfyUI-LTXVideo` in the list of nodes and follow installation instructions.\n\n### Manual installation\n\n1. Install ComfyUI\n2. Clone this repository to `custom-nodes` folder in your ComfyUI installation directory.\n3. Install the required packages:\n\n```bash\ncd custom_nodes/ComfyUI-LTXVideo \u0026\u0026 pip install -r requirements.txt\n```\n\nFor portable ComfyUI installations, run\n\n```\n.\\python_embeded\\python.exe -m pip install -r .\\ComfyUI\\custom_nodes\\ComfyUI-LTXVideo\\requirements.txt\n```\n\n### Models\n\n1. Download [ltx-video-2b-v0.9.1.safetensors](https://huggingface.co/Lightricks/LTX-Video/blob/main/ltx-video-2b-v0.9.1.safetensors) from Hugging Face and place it under `models/checkpoints`.\n2. Install one of the t5 text encoders, for example [google_t5-v1_1-xxl_encoderonly](https://huggingface.co/mcmonkey/google_t5-v1_1-xxl_encoderonly/tree/main). You can install it using ComfyUI Model Manager.\n\n## Example workflows\n\nNote that to run the example workflows, you need to have some additional custom nodes, like [ComfyUI-VideoHelperSuite](https://github.com/kosinkadink/ComfyUI-VideoHelperSuite) and others, installed. You can do it by pressing \"Install Missing Custom Nodes\" button in ComfyUI Manager.\n\n### Image-to-video\n\n[Download workflow](assets/ltxvideo-i2v.json)\n![workflow](assets/ltxvideo-i2v.png)\n\n### Text-to-video\n\n[Download workflow](assets/ltxvideo-t2v.json)\n![workflow](assets/ltxvideo-t2v.png)\n\n### Frame Interpolation\n\n[Download workflow](assets/ltxvideo-frame-interpolation.json)\n![workflow](assets/ltxvideo-frame-interpolation.png)\n\n### First Sequence Conditioning\n\n[Download workflow](assets/ltxvideo-first-sequence-conditioning.json)\n![workflow](assets/ltxvideo-first-sequence-conditioning.png)\n\n### Last Sequence Conditioning\n\n[Download workflow](assets/ltxvideo-last-sequence-conditioning.json)\n![workflow](assets/ltxvideo-last-sequence-conditioning.png)\n\n### Flow Edit\n\n[Download workflow](tricks/assets/ltxvideo-flow-edit.json)\n![workflow](tricks/assets/ltxvideo-flow-edit.png)\n\n### RF Edit\n\n[Download workflow](tricks/assets/ltxvideo-rf-edit.json)\n![workflow](tricks/assets/ltxvideo-rf-edit.png)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flightricks%2Fcomfyui-ltxvideo","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flightricks%2Fcomfyui-ltxvideo","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flightricks%2Fcomfyui-ltxvideo/lists"}
