Start with a photo that says something.
Choose a sharp, well-lit image with a clear subject. A portrait, a favorite landscape or a small everyday moment can all give an effect a useful starting point. Avoid tiny screenshots and heavily blurred images.
Find the right kind of movement.
Choose an effect that fits the image. A portrait works well with subtle motion; an expansive landscape gives a camera movement more room to breathe. The gallery images are visual concepts to help you choose a direction, rather than a promise of an identical output.
Give it a format.
Vertical 9:16 works for a full-screen social story. Landscape 16:9 gives a scene more space, while square 1:1 keeps things compact. Pick five or ten seconds and check the credit quote before generating.
Review the whole clip.
When the video is ready, watch it from start to finish. Check faces, hands, text and transitions. AI can introduce unexpected details, so choose the result you feel comfortable sharing and make another take when needed.
