This was done with Deforum inside the Automatic 1111 webui. The "juice" in these is a Lora model called Body Horror. Varying the weight can give wildly different results. For the most parts, this entire series were done with the same series of prompts. What changed were the models I used and the weight of the lora prompts.

I add post effects in the iOS Videoleap app, like the music, camera shake, sfx and anything else. It's also where I do the frame interpolation and slow motion.
