Two People, One Song: Taking Turns on a Lip-Sync Duet

1. Choose two sections of the song, one per person. A section lasts as long as the video: 5, 8, 10, 12 or 15 seconds in the Hotel Lobby booth.
2. Upload a photo of each person, with the first singer on the left.
3. In Video & sound, pick Your song and upload the file (MP3, WAV or M4A, any length). Slide the orange frame onto the first section and create.
4. Once that video is done, slide the orange frame to the second section and tap “Hand the mic to the other one” below the player. The photos switch sides and a second video starts with the new section. Swapping the photos by hand and pressing Create does the same.
5. Download both MP4s and place them back to back in CapCut, iMovie or another editor.

Two videos cost double: 12 credits for a pair of 12-second videos at 480p. Each one is charged when you create it, and a failed render is refunded.

If you each want to sing the same line, keep the orange frame in place and tap “Hand the mic to the other one” after the first render. You end up with two takes of one section, each with a different person in front, ready to post as a pair or as a before-and-after.

• Each video starts the routine from the top, so the join between the two sections is visible. Cutting on a strong beat hides it best.
• Choose sections where the vocal is clear, since the front person lip-syncs to that voice.
• Faces, moves and mouth shapes vary between renders, so the two videos will not match perfectly.
• The two-video route relies only on features the generator already has; it is a workaround, not a built-in duet mode.

If the back-and-forth matters more than your own recording, switch to a Seedance model and leave Both rap on (it is on by default). The AI writes a verse about your topic and the two of you trade lines inside a single video. On Seedance 2.0 Mini at 720p, a 12-second AI rap is 10 credits, whichever stage you pick.
