iPhone Kupi Dance AI sound and download
Updated 2026-10-31 · By Kupi Dance AI
Short answer: your download is a 15-second portrait MP4 with the original recording restored over the generated picture. Both 480p and 720p HD use the same routine and sound. Review the finished video and the platform's music rules before posting.

What the finished file includes
The file contains the personalized dance and an audio track in one MP4. You do not need to combine a silent picture with a separate song yourself. The frame is vertical, with a 9:16 aspect ratio, and the target length is 15 seconds. The current template features exactly one person from one uploaded photograph; there is no group or extra-friend version.
The default quality is 480p. Choosing 720p HD changes the picture resolution while keeping the duration and routine the same. The quality choice is made before generation and determines the credit amount shown on the button. Downloading a completed result is different from starting a new render, so review the existing result before deciding to make another version.
How the sound matches the picture
The dance follows a fixed performance rather than a newly improvised soundtrack. Generated picture can finish slightly earlier than its reference, so the picture is fitted to the selected duration before the original recording is restored. This adjustment is intended to preserve the end of the recording instead of losing its final fraction of a second.
The soundtrack is the recognizable sound from the trend, not a new recording in the uploaded person's voice. The uploaded photograph does not authorize voice impersonation or imply that the person actually sang the song. Mouth movement is generated and may not align perfectly with every syllable. Listen to the result and watch the face before deciding where to share it.
Check the result before saving and posting
Use the finished result's download control and keep the MP4 in a location where your browser can save files. On a phone, the browser may first put it in Downloads or the Files app rather than directly in the photo library. The exact destination depends on your browser and device settings. Open the saved file to confirm it plays with sound.
If a browser blocks an automatic download, try the explicit download control from the completed result instead of starting generation again. Check that the video has finished rather than remaining in progress. If a render fails or reaches its time limit, the generation credits return automatically. A failed download should be investigated separately from whether the video was successfully generated.
