The prompt starts with role assignment rather than visual adjectives: Image 1 is the left performer and Image 2 is the right performer. It then asks the model to keep the room, the hanging microphone, the camera path, the lighting and the music unchanged, so the two photos stay the only variable. Movement and framing come from the fixed plate.
The prompt keeps a medium-wide camera, one hanging microphone, restrained gestures and warm orange studio light instead of inventing new ones. It avoids rapid cuts, spinning cameras, crowds and physical contact because those increase identity mixing.
A pet prompt should name the visual features that must remain stable: fur markings, breed, face shape, ear position, and body proportions. Ask for small rhythmic head and paw movements instead of human choreography. Add no logos and no text to avoid artifacts on the backdrop.
