Curtain Closing — Google Flow Tutorial

Create a highly realistic smartphone-style nighttime video.

Use the uploaded product image only as the visual reference for the food/product the girl is eating. The girl must be eating the exact same product shown in the reference image. Preserve its recognizable shape, size, ingredients, texture, colors, filling, and overall appearance. Do not redesign it, replace it with another food, or change its packaging/product appearance.

Opening: Start with a wide nighttime city establishing shot from inside or near a neighboring apartment. Across the street, among many dark apartment windows, one window is glowing with warm yellow-orange light. Through that window, a young woman can be seen sitting at a table and eating the referenced product.

The entire scene should feel like it is being casually filmed from far away on a smartphone.

Camera movement:
For the first few seconds, keep the shot wide and distant. Around the 3-second mark, slowly begin a natural digital smartphone zoom toward the illuminated window. The zoom should not be perfectly smooth or cinematic. Include very subtle handheld shake, small framing corrections, realistic low-light grain, digital zoom softness, reflections, and slight nighttime image noise.

As the camera gets closer, reveal the girl more clearly. She remains seated the entire time.

She is naturally and casually eating the exact product from the uploaded reference image. Her attention is completely focused on the food at first. Her body language should feel relaxed and unaware that someone is filming her.

Keep the eating movements realistic: natural bites, chewing, hand movements, and interaction with the food. Do not make the product float, deform, change shape, or disappear unnaturally between frames.

A few loose strands of her hair can move slightly around her face. The apartment lighting is warm and cozy, contrasting with the colder dark exterior.

Discovery moment:
Around the 10-second mark, while she is still eating, she suddenly notices something outside. She pauses slightly, lifts her head, and looks directly toward the distant camera through the window.

Her reaction should be subtle and realistic at first: confusion, then realization that someone may be filming her.

She does not stand up.

She becomes visibly annoyed and gives the camera an irritated, uncomfortable look. Avoid exaggerated acting or cartoonish facial expressions.

White Curtain action:
Still seated, she reaches toward the curtain with one hand and quickly pulls it across the window because she is annoyed about being filmed.

The curtain movement must be physically realistic.

As she begins pulling the curtain, she may still be partially visible through the remaining open section of the window for a moment. Do not make her or the food instantly disappear.

The curtain should gradually cover her and the table naturally until the window is almost completely blocked.

At the very end, leave a small portion of the curtain/window slightly not fully closed for a brief moment, rather than making it snap perfectly shut instantly. Then end the recording naturally.

Visual style:
Ultra-realistic, spontaneous smartphone footage.
POV from a neighboring building.
Natural facial expressions and body movements.
Realistic distance and perspective.
Warm indoor apartment light against a cold nighttime city environment.
Subtle handheld camera shake.
Realistic smartphone digital zoom.
Natural low-light grain and reflections.
No cinematic crane movements or impossible camera motion.

Strict sequence:
Wide distant nighttime window → girl eating the exact referenced product → slow smartphone digital zoom → camera gets close enough to see her eating → she suddenly notices the camera → brief direct eye contact → annoyed expression → remains seated → reaches for curtain → naturally pulls curtain across → she gradually disappears behind it → curtain is left just slightly open at the end → recording stops.

Important restrictions:
Do not change the referenced food/product design.
Do not replace it with a generic sandwich or different meal.
Do not alter its shape or ingredients during the video.
Do not make the girl stand up.
Do not make her walk toward the window.
Do not make the curtain close before she notices the camera.
Do not make the curtain instantly teleport closed.
Do not make the camera physically fly toward the apartment; use digital smartphone zoom only.
No music.
No captions.
No subtitles.
No text overlays.
No logos or watermarks.
No exaggerated reactions.
No artificial-looking facial animation.
Everything must feel accidental, candid, natural, and realistically filmed from far away on a phone.
