AI rap video and lip sync: know what you’re making.
An AI rap video can mean a new performance created with its own sound, or a video edited to match a recording you already have. Those are different workflows. Here is what duet.room supports, with real examples you can listen to before choosing.
Original rap, generated with the video
Original duo rap generates short original verses, a new beat, voices and mouth movement together from two photos. In rap mode, the left and right performers take turns on our short original verses, with a shared finish in the longer clip. Mouth movement is requested to match the newly generated vocals. The current template does not let you upload a song, choose a singer’s voice or enter arbitrary lyrics.
For example, the opening lines are “Two friends, one room” and “We make our own groove.” The 10- and 15-second versions add more original lines. Play the real rap examples with sound to judge the style and pacing. The 5-second example is a raw test; customer free previews include a watermark.
What does “lip sync” mean here?
The model generates audio and visible performance together. It is not a dedicated editor that takes an existing audio track and forces every mouth shape to follow it. Generated syllables, voices and timing can vary. We do not promise frame-perfect or word-for-word synchronization for every pair of photos.
| Your goal | duet.room workflow |
|---|---|
| Two photos → an original duo rap | Original duo rap mode |
| Two photos → dancing to an instrumental | Instrumental dance mode |
| Upload a song and synchronize exact words | Audio upload and lip-sync editing are not supported |
| Clone an artist’s voice or reproduce the original Hotel Lobby track | Not provided |
Start short, then review the full result
Upload one clear photo per adult with their permission, set left and right, and choose sound mode. A free 5-second preview (480p, watermarked, once per account) helps check the pair. A 10-second video costs 35 credits and a 15-second video costs 50 credits, at 720p. Credit packs start at $9.99 for 100 credits; there is no subscription.
The full video is a new generation from the same photos and sound mode. It can differ from the preview. Check who speaks each line, whether each face stays recognisable, and whether the voice and mouth movement feel aligned. Rap outputs are reviewed before delivery; if a result cannot pass our checks within the delivery window, credits return automatically. A failed free preview restores your preview eligibility.
Why results can vary
Covered faces, extreme angles, cropped bodies and similar-looking inputs can make two-person identity harder to preserve. Both performers share a shot, so turn-taking matters as much as mouth movement. Our three September 30 tests used the same original AI character pair and were accepted by the site owner after playback; they show that pair’s result, not a guarantee for every future input.
