    LTXV Keyframe Interpolation and Img2Video Workflow - v2.0
    NSFW

    Workflow for ComfyUI that utilizes image blending between multiple generations of Keyframes to create extended morphing sequences. Can do Img2Vid primarily, and with appropriately processed keyframes (i.e. background identical or very similar) handles morphing characters very well.

    Are you on the nightly of Lightricks/ComfyUI-LTXVideo: LTX-Video Support for ComfyUI

    I'm by no means an expert but seems like those nodes should go with it.

    @katsumend yeah i fixed it by installing that git repo manually,
    I assumed that ComfortUIManager would have those nodes in its database, but I was wrong.

    Error that comes up while trying to install missing custom nodes: "Failed to find the following ComfyRegistry list. The cache may be outdated, or the nodes may have been removed from ComfyRegistry." They aren't on Comfy for some reason. Had to lower security level to weak before installing from the Git Hub. I'm eager to try this out too.

    @jimboom006 I will have to look into this... don't love that! BTW I think we all need to be trying to get Wan I2V start-and-end frame working.... I heard it might be possible.

    How much VRAM is needed for something like this?

    Not a lot.... not sure on the exact but just whatever ltx requires.

    Would you mind sharing your ComfyUI version and the versions of your custom nodes? Installing the missing nodes via the manager always breaks my setup and needs a fresh ComfyUI installation to recover.
