AI Video, Explained
How AI Turns a Photo Into a Video
AI video models take a single image and generate a sequence of new frames that plausibly follow from it, guided by a text prompt describing what should happen.
It predicts frames, not edits them
The model is not cutting or warping your photo. It is generating entirely new images, one after another, that stay consistent with the first frame and each other.
The prompt sets the action
A written instruction — hands enter frame, cut the hair, reveal a bob — tells the model what motion to build. The photo tells it who the person is and what the scene looks like.
Consistency is the hard part
Keeping a face, background, and lighting stable across dozens of generated frames is what separates a convincing clip from a melting one, and it is why the models are large and slow.
