Image-to-video FAQ
1. How long does image-to-video generation take?#
There is no verified completion-time guarantee in the supplied baseline. Follow the displayed queue or job status, and confirm a job has failed before submitting it again.
2. Which image formats should I upload?#
Check the selected service’s upload controls for accepted formats and size limits. Use a sharp, correctly oriented image; the verified information does not establish a shared format list.
3. What should an image-to-video prompt say?#
Describe the change rather than the whole picture: use “subject action + environmental motion + camera movement + pace + constraint,” such as “The cyclist looks left; leaves move in a light breeze; slow push-in; keep the face and bicycle unchanged.”
4. How can I keep a face consistent?#
Start with a clear, front-facing face, request small movements, avoid fast head turns or extreme camera angles, keep the clip short, and reuse the same reference or consistency settings when the tool provides them.
5. Why do hands, text, or background objects become distorted?#
The model must invent unseen intermediate frames, so fine lettering, fingers, and newly revealed surfaces are fragile; reduce the motion, lock the camera, crop unstable details, or add exact text later in an editor.
6. What output resolution can I expect?#
Resolution depends on the service and plan, and free modes may use draft or 480p output; choose the highest available export only after the motion is clean, because upscaling cannot fix warped content.
7. Will a free image-to-video tool add a watermark?#
PixVerse, Leonardo, and Runway watermark free video output. Pika’s watermark status needs fresh verification because the supplied sources conflict, while Dreamina’s policy remains unclear. Check the downloaded file before publishing.
8. Can I use the generated video commercially?#
Check both the generator’s current terms and the source image’s license. A free plan or clean export does not prove commercial permission, and permission to use the output does not clear rights to uploaded assets.
9. Are my uploaded images private?#
Do not assume so: Leonardo’s free creations may be public, and retention, sharing, and training policies vary by provider. Avoid uploading sensitive faces, IDs, client work, or unreleased products unless the terms and controls are acceptable.
10. What should I do when a free generation fails?#
Free usually means a credit allowance, trial, queue, or reduced mode rather than unlimited use; if a job fails, check service status, wait for capacity, simplify the prompt, reduce duration or resolution, confirm the file format, and avoid repeatedly spending credits on the same stalled request.
