What image-to-video AI actually does
Image-to-video AI starts from a photo, not a text prompt. You give it a still you already have — on Ponytale, a photo of the AI girl you designed — and it adds motion: a soft smile and a turn toward the camera, a wave, a kiss blown your way. The result is a short clip of the exact person in the photo, now moving.
That starting point is the whole advantage. Text-to-video has to invent a person from scratch every time, so you never get the same character twice. Image-to-video keeps the face, build, and features from your photo, so the AI girl you built is the AI girl in the clip — not a stranger who happens to look similar.
