| # LTX Ripple |
|
|
| ### Edit one frame. Ripple the change through the whole video. |
|
|
| LTX Ripple is a **First Frame All Frames (FFAF) IC-LoRA** for [LTX-2.5](https://huggingface.co/Lightricks/LTX-2.5). It allows you to make LTX as powerful as your favorite image editor, with smart first frame propagation that understands the edit contextually. |

|
|
| ## How it works |
|
|
| 1. Input your video. |
| 2. Edit or replace its first frame. |
| 3. LTX Ripple will figure out the rest of the video based on your image edit. |
|
|
| You may also give a brief description of what you changed to help it along, but the LoRA can work without even prompting anything. |
|
|
| Useful applications include: |
|
|
| - Adding Special Effects |
| - 3D model re/texturing |
| - Style Change |
| - Light source / time of day change |
| - Character Attribute Change |
| - Background Change |
| - Weather Change |
| - Archviz Retexturing |
| - Title/Logo Replacement |
| - Object Addition / Removal / Replacement |
| - Sharpening / Blurring |
|
|
| ## Recommended strength setting: 1.35 |
| Increase the LoRA strength when the edit is not being carried through strongly enough. Decrease it when the output changes content that should remain unchanged. |
|
|
| ## Prompting |
|
|
| The default prompt used by the workflow is: |
|
|
| > Use the reference video for motion, timing, camera movement, composition, and unchanged scene content, while consistently propagating the visual edit established in the first frame throughout the video. |
|
|
| For difficult edits, add a short description of the changed first frame. For example, describe the new lighting, object, material, style, or background that should remain consistent across the video. |
|
|
| ## Limitations and tips |
|
|
| - The first frame is the key control signal, so make the edit clear and coherent before running the video. |
| - Stronger edits may need a higher LoRA strength and a more explicit prompt. |
| - Very large changes, heavy occlusion, fast motion, or content absent from the source video may reduce consistency. |
| - Results depend on the LTX-2.5 checkpoint, resolution, frame count, sampler settings, and available hardware. |
