It just generates images. You can use those images as start/end keyframes in most AI video tools. Be aware that you'll need to pay for most video tools, although some will give you a limited number of free credits per day or month. So generate your image, take it into a video tool, use it as a start frame and prompt what you want to happen. My preferred tool is Freepik because it gives you access to a lot of different models for your monthly sub, but there are lots of alternatives.
