# ComfyUI-LTXVideo-Extra
|
|
|
|
Extra nodes for LTX-2 video generation in ComfyUI.
|
|
|
|
## Nodes

|
### LTXV Img To Video Inplace At Index
|
|
|
|
Enhanced version of the built-in `LTXVImgToVideoInplace` that supports:
|
|
|
|
- **Arbitrary frame placement** — place an image at any frame, not just frame 0. Use `frame_idx=-1` for the last frame.
|
|
- **Chainable noise masks** — chain multiple instances to condition multiple frames (e.g., first + last frame) without masks overwriting each other.
|
|
- **Preprocessing** — CRF compression, Gaussian blur, interpolation method, and crop mode (matching `LTXVAddGuideAdvanced`).
|
|
|
|
#### Example: First + Last Frame Conditioning with IC-LoRA
|
|
|
|
```
|
|
EmptyLTXVLatentVideo (97 frames)
|
|
→ LTXV Img To Video Inplace At Index (frame_idx=0, first frame)
|
|
→ LTXV Img To Video Inplace At Index (frame_idx=-1, last frame)
|
|
→ Add Video IC-LoRA Guide (driving video)
|
|
→ LTXVCropGuides
|
|
→ CFGGuider + SamplerCustomAdvanced
|
|
```
|
|
|
|
## Install
