Prompt

In 【scene/background】, the frame shows 【subject count and type description】—【subject 1 description】, 【subject 2 description】… Their initial state is: 【action state, e.g., standing, sitting, looking up】, with 【emotion keywords】 in their expressions. At this moment, the transformation into mermaids is happening: each subject undergoes changes: the scene shifts to an underwater world; the subjects have fully transformed into merfolk, wearing scale-like silver breastplates and tails, with clearly defined muscles and determined eyes. Around them are flowing sea grass and soft light spots; underwater plants such as coral and seaweed dance in the current, dreamy and beautiful. Note: the subjects here can be people, actions, objects, etc.\nRequirements:
1. Replace the content inside 【】 above according to the specific image. Describe the initial state based on the subjects' state in the image.
2. If the image is a close-up or medium shot, set Camera Movement to `Zoom out`.
3. If there are two or more subjects in the image, both should be performing `the specific transformation here`.
4. Describe in detail each subject's transformation process, especially action details and how the changes occur. (To distinguish subjects, use obvious distinguishing features, e.g., the man on the left, the woman on the right / the man in a black hoodie, the little girl in a white dress, etc.)

FAQs

Can I use a photo with my boyfriend/girlfriend?

Yes! This template supports Two People. Upload a couple's photo to create a romantic "Merman and Mermaid" fantasy video.

Does it work on animals?

Absolutely. It supports Pets. Uploading a dog or cat will result in a cute and funny video where they get a mermaid tail!

Do I need to wear a bikini?

Not necessarily, but wearing sleeveless tops, swimwear, or tight clothing helps the AI generate the mermaid costume (seashell bra/scales) more naturally.

Is the background always the ocean?

Yes, the AI automatically replaces your original background with a high-quality, animated underwater scene to complete the transformation.
