Video and music are separate deliverables
A dance-themed tool can generate a visual performance without providing the commercial song. Adding a track afterward does not automatically grant permission to distribute it. Audio availability and allowed use can differ by platform, territory and account type; check the source's current terms.
Check the whole clip, not only the thumbnail
Play from beginning to end. Look at identity, hands, overlapping bodies and clothing during turns. A strong first frame cannot prove a usable final video. The local preview has a visible demo label because it is a photo composition rather than an AI performance.
Prepare the right frame
Portrait 9:16 suits a vertical layout; landscape 16:9 gives both subjects more horizontal room. Keep captions and important faces away from edges where a platform interface may cover them. Download the original MP4 before a task expires so you can finish it in your editor.
Share with an accurate description
Get permission from both people and follow the destination platform's current AI disclosure requirements. Do not present a synthetic clip as a real performance or imply endorsement by the artists. This project is independent; the original song, artist name and third-party materials retain their respective ownership.
