This workflow uses lightx2v fp8 models and loras to create believable physics based breast expansion transformation clips. You can set a number to define how many clips you want your full movie to contain and create prompts for each clip. VACE is used to transfer motion between clips and a color fixing method is applied at various places for color consistency.

Because a keyframe storyboard is used instead of the last frame of the previous clip, quality remains intact regardless of the length of the video.

Each segment is saved to disk so RAM use is reasonable. There's never more than 2 videos stored in memory at a time. fp8 models are used and a link to the GGUF version of those models is provided in the workflow. All core downloads are linked. optional loras can be searched for here on civitai.
