How to Make an AI Rap Video From Two Photos
Every trend guide on this blog ends the same way: pick a studio, make the clip. This one is the studio's own manual — the two portraits, the scene, the four bars of lyrics, and every choice on the panel from length to resolution. Ten minutes from photos on your phone to a lip-synced 9:16 rap duet with the vocals already in it.

The studio in one line: two photos, one scene, your own bars — the clip comes back finished.
I. What You Need Before You Start
Three inputs, and the model draws everything else — the second performer, the room, the beat.
- Two portraits — one for the left performer, one for the right. Front-facing, well lit, one person per photo, and photos you have the right to use.
- A scene — two presets are built in (a night alley and a studio booth), or upload a photo of your own place.
- Four bars — your lyrics. A set is prefilled so you can render first and write later.
File limits, so uploads do not bounce: JPG, PNG or WebP, up to 30 MB each, and every edge of the image must land between 256 and 5760 pixels — a normal phone photo clears both with room to spare.
II. The Two Faces — and Why Their Order Matters
The left slot becomes the performer on the left of the frame; the right slot, the one on the right. That is the whole trick and the easiest thing to get wrong: if the duet feels swapped — voices and faces not where you pictured them — swap the two photos before you blame the model.
What makes a good portrait here is the same as what makes a good passport photo: face toward the camera, even light, nothing else in the shot competing for attention. Sunglasses, heavy shadows across the face, or a group photo cropped down all give the model less to hold on to, and it shows in the lip-sync.
III. The Scene — Preset or Your Own Place
Two presets ship with the studio: a night alley and a studio booth. Pick one and you are done — the set, the lighting and the mood come with it.
Or drop in your own background photo. The model rebuilds the scene around it, which is the difference between a clip that reads as your city and one that reads as a stock stage. Busy backgrounds work, but give the eye one clear anchor — a doorway, a sign, a skyline — rather than a crowd.
IV. Your Four Bars — the Lyrics Box
Lyrics get their own box, separate from the director prompt, for a practical reason: you can rewrite one without touching the other. A set of four bars is prefilled so the very first render works with zero writing, and a swap button brings in another set — four are stocked, each with its own mood — without disturbing anything else you have changed.
When you write your own, four short lines are the format. Each line lands on a beat, the two performers trade them, and short lines survive the lip-sync better than dense ones. The full prompt — direction, scene, and your lyrics appended at the end — can run to 7,000 characters, which is far more than a duet needs; the limit is there so ambitious directors are not silently truncated.
V. Length, Shape and What It Costs
Shape
9:16 vertical is the default and the right call for TikTok, Reels and Shorts. Wider shapes — 16:9, 4:3, 21:9 and the rest — are there if the clip is headed for a landscape feed.
Length
4 to 15 seconds on the slider, 6 by default — enough for one exchange between the two performers. Cost scales with seconds, so a first render at 6 tells you most of what a 15-second one will cost.
Resolution
768P is the default; 2K costs more and the button shows exactly how much before you commit. The studio's rule is printed under the button: the credit price is on it the whole time, and a failed run never spends credits.
VI. Generate — and What Happens While You Wait
Pressing generate starts a cloud render — usually a few minutes, and you can leave the tab and come back. You will need an account first; if you are not logged in, a sign-in window opens before anything is sent.
When the clip lands it plays right on the page with a download button under it. If a render fails, the reason comes back in words, not a code — photo too small, prompt too long — and fixing that one thing is usually all the retry needs.
VII. After It Is Done
You get a vertical MP4, finished — vocals, lip-sync, scene and all. It carries an AI-generated label and an identifier inside the file, which is what TikTok, Instagram and YouTube policies and the EU AI Act ask for. Keep the label when you post; cropping it out is the part that breaks those rules.
Results vary run to run — the lip-sync most of all. A second render with the same three photos often lands better than the first, and since a failed run is free, the cheap experiment is one more try, not a new plan.
VIII. Good to Know
- Portraits should be people whose photos you may use — your own, or with permission. It is a hard line, not a suggestion.
- Lyrics you write are yours to clear: a borrowed line from a copyrighted song is a copyright question the render does not answer for you.
- RapReel is an independent, fan-made tool and is not affiliated with the model vendors behind it.
That is the whole manual. Two photos, one scene, four bars — the studio is open at the top of the page.
