Seedance Dialogue Scene With Lip Sync

10 seconds, 16:9, two shots with a hard cut. A late-night diner, rain on the window, neon sign glowing outside. Two fictional characters sit across a booth: [a tired detective in a gray coat] and [a nervous young waiter]. Cinematic realism, moody low light.

Shot 1, 0-5 seconds: Over-the-shoulder shot from behind the waiter, the detective in focus. The detective slides a photo across the table.
Detective's line, in English (calm, quiet): "[You've seen this man before.]"
Hard cut.
Shot 2, 5-10 seconds: Reverse shot, close-up on the waiter. He glances at the photo, then at the door.
Waiter's line, in English (nervous, almost a whisper): "[He comes in every Tuesday. Always alone.]"

Sound: rain on glass, a low fridge hum, a cup set down on the table. Accurate lip sync on both lines. No music, no subtitles, no text on screen.
Keep both characters' faces and clothes the same across the cut. Normal human eyes.
