Choose one location
A station platform, a quiet street, or an apartment hallway gives the viewer a place to understand. Switching locations repeatedly in a short clip makes continuity fragile.
Describe visible details that support the story: empty signs, soft smoke in the distance, scattered paper, or an abandoned vehicle. Avoid filling every frame with anonymous crowds.
Give the characters a single objective
The characters can search, hide, cross a threshold, or find each other. One objective makes cuts and camera movement easier to plan.
Keep the uploaded photos as the identity reference. If a specific facial feature must remain recognizable, make that an explicit review criterion rather than assuming the model will preserve it.
Leave room for the edit
Use longer holds around recognition and shorter cuts for movement. Confirm the output has usable opening and closing frames before adding titles or a soundtrack.
