POV: you went for a late swim Seedance 2.5 on @makeugc. I just wanted to test how real it looks. Now I can't unsee it 💀 Would you feed them? Prompt: Real amateur iPhone video, vertical, filmed handheld at night by someone crouching at the edge of a hotel swimming pool at 2am, the phone held low at water level. Harsh direct phone flash mixed with the turquoise glow of the underwater pool lights, shaky handheld camera, auto-exposure flicker, visible digital noise and grain, slight motion blur, candid unedited footage, no cinematic color grading, looks like a real video posted on social media. From the very first frame, two beautiful young women with long wet hair and realistic skin texture, wearing bikini tops, are in the water right next to the pool edge, laughing hysterically with slightly unhinged energy, and behind them their large realistic fish tails with wet iridescent scales and fins slap and flick out of the water, clearly visible under the flash. They push closer to the camera and rest their elbows on the wet tiles, faces almost touching the lens, giggling. The filmer's hand enters the frame holding a few pieces of sushi on the open palm; the two mermaids snap at the sushi with their mouths like playful seals, competing for it, one steals a piece from the other, both chewing and laughing with their mouths full, grains of rice stuck to their lips and cheeks. Then one of them excitedly slaps her tail on the water and a big splash hits the camera, water droplets on the lens, both laughing loudly. Real physics of water and wet hair, natural sounds only: splashing, laughter, giggles, no music.

Step 2: same image, same model, two different prompts. Seedance 2.5 on @makeugc Left: my first prompt. She barely moves. Right: I rewrote it. Fast tempo, 3 specific tricks, full 360 camera orbit. The model wasn’t the problem. My prompt was.
