Extra nodes for LTX-2 video generation in ComfyUI.

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)

  → CFGGuider + SamplerCustomAdvanced
