How to Choose a Photo for Photo to Video AI
Which photos turn into smooth AI videos, which ones struggle, and how to write a short motion prompt.
The photo you upload decides most of what the video looks like. A few minutes spent choosing it saves credits, because a clear picture with an obvious subject usually animates well on the first try.
Photos that animate well
- Sharp, well-lit pictures. Blur and heavy noise turn into wobble once the picture moves.
- One clear subject. A portrait, a pet or a single product gives the model something to focus on.
- Room around the subject. If a head or hand is cropped at the edge, the model has to invent what is outside the frame.
- Natural motion cues. Hair, water, clouds, fabric and smoke already suggest how they should move.
Photos that struggle
- Crowded group shots, where many faces can drift in different directions.
- Heavily filtered or low-resolution pictures.
- Hands holding small objects, which can bend or merge during motion.
- Text on signs and packaging, which often warps as the camera moves.
Writing a short motion prompt
The prompt is optional, but one sentence helps. Describe the motion, not the picture, because the model can already see the photo.
- Good: A gentle smile, a slow blink, hair moving in a light breeze.
- Good: Slow push-in toward the subject, clouds drifting across the sky.
- Less useful: A woman with brown hair standing in a park.
Keep the motion small. Big instructions such as running, dancing or turning around ask the model to invent a lot, and results are less predictable.
Pick length and quality last
Shorter videos cost fewer credits and keep the motion more stable, so start with the shortest length. The generator shows the credit price before you submit, and changing the model, length or quality updates it. If the first video looks good, raise the quality for a final version.
When you are ready, open the generator and upload your photo.
