What you'll need
30 min- OpenArt
Two versions of the same woman stand face to face in a black room. They hold on to each other. One of them can’t stop laughing. The other one is “dead inside”. She is black and white, and her face shows nothing at all.
The camera goes all the way around them in 14 seconds and ends where it started, so the video loops. This dead inside AI video prompt is the version of a trend where one twin laughs and the other cries. Here the second twin does not even cry.
You need two character sheets of yourself, one happy and one tired, and one video prompt. All three prompts are below.
The whole process
- Take one clear photo of yourself.
- Make two character sheets from it: a happy look and a "dead inside" look.
- Open OpenArt, go to video and pick Seedance 2.5.
- Add the happy sheet first and the "dead inside" sheet second. Set 14 seconds.
- Paste the video prompt and generate.
- Post it on Instagram and add the music in the Reels editor.
What happens in 14 seconds
| Time | Camera | What happens |
|---|---|---|
| 0–3.5s | Side view | The happy twin throws her head back laughing. The other one just looks at her |
| 3.5–7s | Over the happy twin’s shoulder | She leans in and giggles. The other one blinks once, slowly |
| 7–10.5s | The other side | She wipes a tear from laughing. The other one only sways a little |
| 10.5–14s | Back to the start | One more big laugh. The camera ends on the first side view |
Make two character sheets
The model needs to know both versions of you from the front and from the side. So make two sheets from the same photo. The face stays the same. Only the clothes, the hair and the mood change.
Use any image model in OpenArt that takes a reference picture. Add your photo as Image 1, set the shape to 16:9 and paste the first prompt.
Create an ultra-photorealistic CHARACTER REFERENCE SHEET of one person, 16:9, using Image 1 as the only identity reference.
Keep from Image 1: the exact face, facial proportions, eye shape and colour, nose, lips, skin tone, freckles and moles, age, body build and hair colour. Do not beautify or change the face.
Outfit: an oversized bright lime-green blazer, a lime-green turtleneck crop top, wide lime-green trousers and lime pointed shoes. Small gold hoop earrings. Hair: long, loose and wavy. Mood: happy, warm, full of life.
Layout on a plain light-grey studio background: LEFT: one full-body view from the front, head to shoes, relaxed standing pose. RIGHT: a 2x2 grid of head-and-shoulders portraits: a soft smile looking away, a big smile, laughing with eyes half closed, and laughing with the head tilted back and one hand in the hair.
Soft even studio light, 50mm lens look, real skin texture, sharp hair strands and fabric. Same person and same outfit in every panel. One person only. No text, no logos, no watermark, no illustration.
Now make the second sheet from the same photo with this prompt.
Create an ultra-photorealistic CHARACTER REFERENCE SHEET of one person, 16:9, using Image 1 as the only identity reference.
Keep from Image 1: the exact face, facial proportions, eye shape and colour, nose, lips, skin tone, freckles and moles, age, body build and hair colour. Do not beautify or change the face.
Outfit: an oversized washed black hoodie, black sweatpants and worn black canvas sneakers. No jewellery. Hair: a messy high bun with loose strands falling around the face. Mood: tired, empty, emotionless. No makeup look.
Layout on a plain light-grey studio background: LEFT: one full-body view from the front, head to shoes, hands in the hoodie pocket. RIGHT: a 2x2 grid of head-and-shoulders portraits, all with a blank face: looking away, looking down, looking straight into the camera, and a slight head tilt. No smile in any panel.
Soft even studio light, 50mm lens look, real skin texture, sharp hair strands and fabric. Same person and same outfit in every panel. One person only. No text, no logos, no watermark, no illustration.
Put the two sheets next to each other before you go on. It has to be clearly the same face. If one sheet looks like a different person, make it again.
Generate the video
Open OpenArt, go to video and pick Seedance 2.5.
Add the happy sheet first and the “dead inside” sheet second. The order matters, because the prompt says which picture is which twin. Set the length to 14 seconds and paste the prompt as it is.
We made ours in a 4:3 shape and kept it. You can pick 9:16 for a full-screen reel, but then the two women stand closer to the edges.
[References] <Joy> corresponds to @Image 1. Use only her face, freckles, long loose wavy copper-red hair, gold hoop earrings and the lime-green oversized blazer with lime turtleneck crop top. Do not use the light grey studio background, the collage layout, the frame borders or the “Outfit 01” label. <Numb> corresponds to @Image 2. Use only her face, freckles, messy high bun with loose strands and the black oversized hoodie. Do not use the light grey studio background, the collage layout, the frame borders or the “Outfit 02” label. @Image 1 and @Image 2 are the same woman. The output contains exactly two women, Joy and Numb, and nobody else.
[Look — locked for the whole video] Pitch-black studio void, no walls, no floor line, no props, the background stays pure black in every direction. One soft key light from above and slightly in front of the pair, plus a gentle rim light that outlines both silhouettes against the black; the light stays fixed in the room while the camera moves around them. Full-frame cinema camera, 50mm lens, shallow depth of field, both faces sharp, fine film grain, deep clean blacks, soft highlight roll-off. Joy is in full natural color: warm skin, copper-red hair, saturated lime-green suit. Numb is completely black-and-white: grey skin, grey hair, grey hoodie, zero color on her, like a monochrome photograph standing inside a color film. She is lit by exactly the same key and rim light as Joy, with matching shadow direction, highlights on her cheekbones and hair, and correct falloff; only her color is removed, never her lighting.
[Generation Goal] One continuous single take, 14 seconds. Medium shot of Joy and Numb standing close, face to face, holding each other the whole time: Joy grips the shoulders of Numb’s hoodie with both hands, Numb loosely holds the lapels of Joy’s blazer. They never let go and never step apart. The camera makes exactly one full 360-degree orbit around the pair at chest height, at a slow, perfectly constant speed, always keeping both women centered in frame. Subject movement and camera movement are independent: the women stay in place, only the camera travels.
[Stage 1 — 0-3.5 seconds] Initial state: side profile two-shot, Joy on the right, Numb on the left, faces close. Primary event: Joy bursts into laughter, head thrown back, mouth wide open, eyes squeezed shut. Numb stares straight at her with a blank face. End state: the camera has moved a quarter turn and now sees Numb’s face over Joy’s shoulder.
[Stage 2 — 3.5-7 seconds] Continue from the previous stage: same grip, same positions, Numb still fully monochrome. Primary event: Joy leans forward into Numb, shoulders shaking, giggling with her forehead almost touching Numb’s cheek. Numb’s expression does not change: relaxed jaw, flat mouth, slow single blink, empty gaze into the distance. End state: the camera reaches the opposite side profile, Numb on the right, Joy on the left.
[Stage 3 — 7-10.5 seconds] Continue from the previous stage: same grip, same positions. Primary event: Joy laughs so hard she wipes a tear with one knuckle and grabs the hoodie again, laughing up at Numb with crinkled eyes. Numb is only swayed slightly by Joy’s shaking, like a doll, no reaction in her face. End state: the camera is behind Numb’s shoulder, seeing Joy’s laughing face.
[Stage 4 — 10.5-14 seconds] Continue from the previous stage: same grip, same positions. Primary event: Joy throws her head back again in a big open-mouthed laugh. Numb keeps looking at her with the same empty, emotionless face. End state: the camera completes the full circle and returns to the exact opening side profile, Joy on the right, Numb on the left.
[Maintain Consistency] Exactly two women for the full 14 seconds. Joy is always in color and always laughing in varied ways; Numb is always black-and-white and shows no emotion at all: no smile, no tears, no frown. Their hairstyles, clothing, grip and left/right placement stay consistent. The background stays pure black, and the camera never stops, reverses or cuts.
Audio includes Joy’s real, breathy, varied laughter, soft fabric rustle, and otherwise silence. No music, no dialogue.
If your sheets look different from ours, change the words in the first two lines to match them. For example, write “short blonde hair” and “denim jacket” instead of “copper-red hair” and “lime-green blazer”.
Add the music on Instagram
The prompt asks for no music on purpose. The trend uses one piano mashup, and it is easier to add it in Instagram than to make the model play it.
The sound is called soulmate x amélie x interstellar x passacaglia.
- Find any reel that already uses this sound. Tap the sound name at the bottom of the reel, then tap Use audio. Instagram opens a new reel with the sound already in it.
- Add your video from the gallery.
- If you start from your own video instead, tap the music note in the Reels editor and search for “soulmate x amélie”. Pick the sound from the list.
- Drag the sound bar to choose which part of the song plays. Start with the slow piano part, so the music feels sad while she laughs.
- Open the volume control and turn the sound of your own video almost to zero. You can keep a little of the laughter under the piano.
Why this prompt works
Each sheet is tied to one name. “Joy” is Image 1 and “Numb” is Image 2. Seedance 2.5 does not guess which picture is which person. If you do not say it, the twins can swap clothes halfway.
The light stays in the room, the camera moves. The prompt says the light “stays fixed in the room while the camera moves around them”. So the shadows turn as the camera turns, and the circle looks real.
The black room still shows the movement. A rim light draws a thin bright line around both women. Without it, the camera turn is hard to see on pure black.
Four stages, four different laughs. Head back, giggling, wiping a tear, head back again. One long “she laughs” gives you the same laugh on a loop.
The ending matches the start. The last stage sends the camera back to the first side view. So the video loops on Instagram without a jump.
Where it goes wrong
| What you got | The fix |
|---|---|
| The black and white twin gets some colour back in her hair | Keep “grey hair, grey hoodie, zero color on her” and generate again |
| She looks flat, like a cut-out | Keep “only her color is removed, never her lighting” |
| The twins swap clothes | Check the upload order. The happy sheet must be first |
| The camera stops or turns back | Keep “never stops, reverses or cuts” and “perfectly constant speed” |
| The camera does not make a full circle | Timing is not exact in Seedance. Generate again or trim the end |
| The dead inside twin smiles | Keep “no smile, no tears, no frown” in the last block |
| A grey studio wall appears | Keep the lines that say not to use the grey background of the sheets |
| A label like “Outfit 01” shows up | Keep the line that bans the label, or crop it off the sheet |
Questions people ask
Which AI model made this video? Seedance 2.5 on OpenArt. It takes two reference images and makes the full 14 seconds in one go.
Can I put myself in it? Yes. Make both character sheets from one photo of you. The video prompt only uses the sheets, so the face comes from your photo.
Does it work vertical? Yes, you can pick 9:16. Ours is 4:3. In a tall frame, the two women stand closer to the sides.
Is the prompt free? Yes. All three prompts on this page are free. You pay only for the generations on OpenArt.
Can the second twin cry instead? Yes. Change the “Numb” lines to crying, tears and a shaking chin. Keep her black and white, so the two looks stay apart.
Ready? Open OpenArt, add your two sheets and paste the prompt.
