How to make a two-person rap video (a duet) with AI
Pick a duet template, Studio Booth Duo or Hotel Lobby Duo, upload one photo of each person, choose a voice for each, and the AI writes the rap for two and lip-syncs both faces. Duets run 10 or 15 seconds and cost 2 credits a second, so 30 credits at most.

The two duet templates
| Template | Scene | Best for |
|---|---|---|
| Studio Booth Duo | Two people sharing one mic in a recording booth | Best friends, couples, siblings, a birthday from two |
| Hotel Lobby Duo | Two rappers in streetwear in a marble hotel lobby | Wedding toasts, best men, a big announcement |
Both put the first photo on the left and the second on the right, keep each face, hair and skin tone, and frame both from the chest or waist up so both mouths stay visible. Each person gets their own voice, male or female.
Sample 1: Studio Booth Duo
Two best friends rap to a third for her 25th birthday. Two female voices, trap beat, hype vibe. Notice the second line explains who is rapping; in a duet that line does a lot of work.
“Jess, it's your birthday and we took the booth tonight”
“Two best friends on the mic and we wrote you every line”
“Twenty-five and glowing, you still own the dance floor”Sample 2: Hotel Lobby Duo
Two best men roast the groom at a wedding. Two male voices on a trap beat with a roast vibe. The lobby, chandelier and gold chains give a toast the scale of a music video.
“Danny's getting married, yo we flew in for the toast”
“Lost his keys, lost his phone, still the man who loves her most”
“Back in college he was burning ramen every night”The two photos
A duet needs two separate photos, one face in each. A single group photo does not work: the template has to know which face goes left and which goes right, and a group shot gives it neither cleanly.
Do
Do
Avoid- Both faces towards the camera, mouths visible, no sunglasses.
- Similar framing in both: two head-and-shoulders selfies match better than a selfie and a full-body shot.
- Daylight in both, so the two faces look like they share a room.
- Upload in the order you want them left to right.
How the lines are split
The rap is written for two from the start: "we" instead of "I", and lines that pass back and forth. In a 15-second duet each person gets about half the clip; the switch happens near the middle of the hook rather than every line, which keeps the mouths readable.
- Line 1: the name and the occasion, from whoever is closest to them.
- Line 2: who the two of you are. "Two best friends", "the best men", "your kids".
- Lines 3 and 4: the other voice, with the joke and the wish.
Pick two different voices, male and female, for the clearest hand-off. Two of the same voice still works, as both samples show.
Writing a hook for two voices
A duet hook should sound like two people talking to one. Write it as "we", give each voice a clear job, and keep the lines short enough that the hand-off is easy to follow.
Line 1 sets the scene, line 2 says who is rapping, and lines 3 and 4 hand over to the second voice for the joke and the wish. In a roast duet, let the first voice tease and the second voice defend; the back-and-forth makes it feel like a real toast.
| Pair | Voice 1 | Voice 2 | Vibe |
|---|---|---|---|
| Best friends | Female | Female | Hype |
| Best men | Male | Male | Roast |
| Couple | Male | Female | Sweet |
| Brother and sister | Male | Female | Sweet or hype |
Length and cost
| Length | Duet | One person |
|---|---|---|
| 10 seconds | 20 credits | 10 credits |
| 15 seconds | 30 credits | 15 credits |
Duets cost twice as much per second because there are two faces to animate, and they run 10 or 15 seconds. 15 seconds fits the full 4-line hook, which is what most duets need. For a longer rap from two people, make the whole song as an MP3, or make two solo videos.
Common duet problems and fixes
| Problem | Why it happens | Fix |
|---|---|---|
| The people are on the wrong sides | The photos went in the other order | Upload the left person first |
| One face looks less like them | One photo is darker or further away | Use two photos with similar light and framing |
| It is hard to tell who is rapping | Both voices are the same | Pick one male and one female voice |
| The hook feels rushed | Too much in 10 seconds | Choose 15 seconds for the full hook |
| A third friend wants in | Duets take two people | Name the third in the lyrics, or make a second video |
The first frame is free, so check both faces in it before you render. If one looks off, swap just that photo and check again.
Duet ideas
- Two siblings rapping to a parent on a birthday or Mother’s Day.
- The best man and maid of honour, as a toast that plays on the big screen.
- A couple announcing an engagement, a move or a baby.
