Monokini AI Video

A monokini AI video turns one swimwear photo into a slow, sunlit clip. The open-sided one-piece stays a swimsuit from the first frame to the last, while light, wet skin and a slow turn do the work. Upload a photo of yourself or of an adult who agreed, add one move, and Sirena renders a vertical clip with the sound of the pool. 18+, never explicit.

New · 16 models · 8 scenes

Ready-to-shoot scenes. One tap, they let loose.

A kiss in the club bathroom, a hand that wanders in the taxi at 4 a.m., a shower for two after the party… Pick a scene: the models and the full prompt drop straight into the studio. Tweak it, or let them play it exactly as written.

01
Club bathroom
Duo · Kiara & Lena
@Image 1 and @Image 2 in tight party dresses, one black with thin straps, the other silver and very short, in a nightclub bathroom: cracked white tiles, mirror smudged with fingerprints, paper on the floor, a purple neon light flickering and buzzing, bass thumping behind the door, a toilet flushing in the distance. @Image 2 holds the phone at arm's length, the frame tilts, she laughs: "Okay okay, we're filming this." @Image 1, leaning on the sink, bites her lip and grabs @Image 2 by the back of the neck: "Come here." Kiss with tongue, slow then more urgent, hands in the hair then on the butt through the dress, @Image 1's strap slips off her shoulder and uncovers a breast, she doesn't pull it back up. Lipstick smeared on both mouths, short breath, @Image 2 looks into the lens: "We're so bad," and they burst out laughing, the phone almost falls, reframes on the ceiling, cut.
02
VIP table twerk
Solo · Sara
@Image 1 in a black Brazilian thong and a sequined crop top pulled up above her navel, high heels, at a VIP table: red velvet booth, low table covered in bottles, sweating ice bucket, sparklers crackling on a bottle, white strobe and green lasers, smoke. Filmed by a friend slumped on the booth who shouts over the music: "Go on, show them!" @Image 1 turns her back to the camera, spreads her legs, hands on her knees, arches her back and twerks to the beat, butt bouncing, thong sinking in, sweat in the small of her back. She turns around laughing hard, hair stuck to her forehead, grabs a bottle by the neck and raises it to the lens: "To tonight, bitches!", drinks, chokes, laughs. Flash from another phone, a bouncer passes by blurred, the friend screams with laughter, the image shakes everywhere.
03
Taxi home
Duo · Mia & Chloe
@Image 1 and @Image 2 in the back of a taxi at 4 a.m., worn black leather seat, an air-freshener tree hanging from the mirror, shop signs and red lights sliding across their faces in blurry patches, the indicator ticking, radio turned low, the driver blurred from behind. @Image 1 holds the phone low, the frame sometimes cuts off their heads. @Image 2, shoes in hand, rests her head on her shoulder: "Best night of my life, I swear." @Image 1 whispers: "Shh, he can hear us," nodding toward the driver, they giggle. @Image 2 lifts her head, their eyes meet, kiss with tongue, slow, @Image 1's hand slides under @Image 2's dress out of frame, @Image 2 closes her eyes and holds her breath, then @Image 1 goes "Shhh" to the lens with a smile, the phone reflected in the window, a pothole shakes them, they laugh.
04
Afterparty in bed
Solo · Yasmine
@Image 1 in a white thong, topless, lying on a hotel bed at 5 a.m.: crumpled white sheets, pillow half on the floor, dress in a ball on the floor, heels knocked over, a water bottle on the nightstand, only the bedside lamp on, yellow light, blind half open on a sky turning blue, distant music through the wall. Running mascara, glitter stuck to her cheek. She films herself at arm's length, hoarse voice: "It's five a.m. and I am not even tired," yawns right in the middle, laughs at her own yawn. She rolls onto her stomach, arches her back, the thong rides up her hips, her butt lifts, she looks over her shoulder: "Okay, maybe a little," blows a kiss to the camera, buries her face in the pillow, says a muffled "Good night", and the phone drops onto the sheet, blurry shot of the lamp.
05
Dancefloor
Duo · Mei & Bianca
@Image 1 in a tight black mini dress with no bra, nipples visible through the fabric, in the middle of a packed dancefloor: red lights, smoke, a disco ball, distorted music crushing the mic, bass shaking the image, strangers' shoulders and arms crossing the frame, a spilled glass on the floor. @Image 2 films very close, at arm's length, the frame cropped and tilted. @Image 1 shouts into the lens: "I can't hear you!" laughing, @Image 2 grabs her by the waist, they dance pressed together, hip to hip, the dress rides up her thighs and @Image 1 lets it, hair stuck down, skin shiny with sweat. Kiss with tongue in the middle of the crowd, a stranger bumps into them, they laugh into the kiss without letting go, @Image 2 shouts "Oops!" and a phone flash blinds them.
06
Shower after the party
Duo · Natalia & Rosa
@Image 1 and @Image 2 in the same shower after coming home from the club: narrow stall with blackened grout, patterned plastic curtain, shampoo bottles on the floor, harsh ceiling light, steam, the sound of water drumming on the tray. @Image 1 holds the phone out of the spray, fog on the lens, makeup running in black streaks, bare breasts, hair slicked down. @Image 2 steps under the water and lets out a little scream: "Oh my god, it's freezing!" @Image 1 laughs: "Come here, I'll warm you up," pulls her close, chest to chest, they kiss under the water, hands on backs and hips, framed at shoulders and faces, water splashes the lens and blurs everything, @Image 1 wipes the lens with her thumb laughing, her fingerprint shows, @Image 2 says "You're getting it wet" and they laugh even harder.
07
Rooftop
Solo · Isla
@Image 1 in a black thong and heels on a rooftop at 3 a.m.: gravel underfoot, cold metal railing, lit-up towers behind, a red sign blinking on a facade, wind whistling in the mic, a siren in the distance. Filmed by a friend whose voice shakes with laughter: "You're not gonna do it!" @Image 1, still wearing a sequined top, answers "Watch me," pulls it off in one move and spins it above her head, topless, goosebumps on her arms, nipples hard from the cold, she shouts at the city "I love this city!", turns around and twerks against the railing laughing hard, a champagne bottle in her hand foaming over her fingers, the friend screams "Oh my god, oh my god!", a streetlight overexposes the image, then it plunges into darkness as she turns.
08
Club cloakroom
Solo · Tina
@Image 1 in the dark cloakroom of a nightclub: racks loaded with jackets and coats, numbered tickets, an empty counter, red light from the corridor filtering through the half-open door, muffled bass, distant voices. Selfie video held at arm's length, strapless dress pulled down to her waist, topless, marks from the dress on her skin. She whispers to the lens with a half smile: "Quick, before someone comes in." She arches against the wall of jackets, slowly caresses her breasts while staring at the camera, visible breathing, bites her lip, her other hand slides down her stomach and out of frame. A door slams in the corridor, she jumps, yanks her dress back up and bursts out laughing, hand over her mouth: "Oh my god, no!", the phone tilts sideways and the video cuts.

What a monokini looks like on video

A monokini is a one-piece built from narrow straps and wide open sides, so the body reads as one long line with light crossing it. In motion the fabric shifts with each step and the shadow moves along the edge of every cut, which shows the shape better than a still photo.

Keep the swimwear clear in your reference. The model reads the cut, colour and straps from the image, so describe movement and light rather than a new outfit.

Real clips from this studio

Monokini prompts to start from

Your swimwear photo is @Image 1. Each prompt keeps the cut and asks for one slow action.

Open-side turn
@Image 1 stands by a turquoise pool in an open-sided monokini, turns slowly from the waist so the cut-outs catch the sun, glances back over her shoulder, slow push-in, warm sunlight and water lapping the tiles.
Wet shoulder
@Image 1 steps out of the shallow end, water running down the straps and sides of her monokini, she pushes wet hair back with one hand and looks at the camera, static medium shot, bright noon light, soft splashing.
Lounger look
@Image 1 lies on a white lounger, adjusts one strap with a slow finger and smiles toward the lens, the camera tilts gently from her feet up to her face, golden afternoon light, cicadas and a light breeze.

Which cut for which shot

Match the open side to the camera so the cut stays readable.

Cut detail	Move	Camera
Thin straps at the shoulder	Turns, lets the hair fall forward	Medium shot, slow push-in
Open waist side	Hand on the hip, slow pivot	Three-quarter angle at waist height
Back cut-out	Looks over the shoulder	Behind the subject, steady dolly
Full silhouette	Walks toward the water	Wide shot, locked camera

A wide, locked shot shows the full cut. A closer move gives the sides more light.

Before you render: a monokini checklist

Open sides can show more or less than you meant. Check before each render:

The sides and straps are visible and unobstructed in the reference photo.
Lighting is even, since harsh contrast across the cut-outs makes the model guess.
The swimwear stays swimwear. Ask for nothing beyond the cut shown in the photo.
Every person is an adult who agreed, and nobody else appears in frame.
One movement only. Slow turns hold the cut far better than fast ones.

Want a new colour? Describe it in the prompt, and keep the cut exactly as the photo shows it.

Monokini clip prices

The price depends only on length and quality, never on the swimsuit:

Price per video, by length and quality
Length	Medium · 480p	High · 720p	Ultra High · 1080p
5 seconds	$5.19	$6.49	$15.59
10 seconds	$6.49	$11.69	$31.19
30 seconds	$15.59	$32.49	$92.29

A quick test: five seconds in Medium 480p, $5.19, shows whether the cut reads well.
The keeper: ten seconds in High 720p at $11.69, or Ultra High 1080p at $31.19 for sharper water.
Pay per video by card or with piments. Confirmed provider failures are restored or refunded.

Monokini AI video questions

Does the video change the cut of the swimsuit?

No. The model follows the cut in your photo, so keep the reference clear and describe movement and light.

Can I use a photo of myself?

Yes, if you are an adult and the photo is yours. Fictional AI models from the library work too.

Why does each render look a little different?

Every render is generated fresh. Keep the same reference, move and light to compare tests fairly.

Does the clip include sound?

Yes, native ambient audio such as water, wind and footsteps when the prompt asks for them. No music is added.

Is it ready for Stories and Reels?

It is a vertical 9:16 MP4. Label it as AI where the platform asks.
