SCENE CONTEXT
A playful vertical selfie video of two second-year Japanese female university students, best friends, both bubbly and full of energy, in the empty tiered lecture hall of the university they both attend, shown in <<<image_3>>>, after the last class of the day. Recreate the rhythm of the hand-sweep gag from <<<video_1>>>: the video is built on deliberate contrast in three parts. (1) It opens with both girls dead serious, like an ID photo. (2) Then the hands sweep across the front girl's face about five times per second, and at every single pass she appears with a completely different exaggerated expression, flickering by rapid-fire — it starts with silly funny faces and builds into a fierce angry face. (3) In the final second, the act collapses and both friends burst into laughter together.
ACTIVE REFERENCES / REFERENCE USAGE
<<<image_1>>> defines the front character's identity, hair and complete outfit: bleached honey-blonde choppy short hair with dark roots at the parting and wispy bangs, two small kelly-green snap hair clips, white cropped ribbed T-shirt, open cobalt-blue zip-up track jacket with two white stripes down each sleeve, small silver hoop earrings. No hat.
<<<image_2>>> defines the rear character's identity, hair and complete outfit: glossy straight black chin-length bob with blunt bangs, white T-shirt, bright kelly-green chunky ribbed knit cardigan with dark buttons and long sleeves, black wide-leg trousers. No hair clip. The blonde girl's green hair clips match her best friend's green cardigan, and both wear plain white T-shirts, the way close best friends do.
Use the large facial portrait on each sheet for facial identity. Take only their faces, hair and clothing from the sheets; do not inherit the grey background, the flat lighting or the three-view layout.
<<<image_3>>> defines the lecture hall: rows of long light-oak desks with grey fabric seats rising in steps behind them, a stairway aisle on the left, pale cream walls, a wooden double door at the top back, tall windows with pale vertical blinds on screen-right with green campus trees in warm sunlight outside, flat white ceiling lights. Adapt its viewing angle to the selfie camera.
<<<video_1>>> controls only the hand choreography, the sweep timing, the small head dips and the relative placement of the two people. Its performers' faces, hair, clothing, cap, room and facial expressions do not transfer. Any watermark or logo in <<<video_1>>> does not appear.
FIRST FRAME
The video begins directly through the phone's front-facing camera. <<<image_1>>> holds the phone at arm's length at about eye level, with her holding hand and the phone outside the frame. Her face and upper chest fill the lower-centre foreground. <<<image_2>>> is close behind her, slightly offset toward screen-right, her chin almost resting on <<<image_1>>>'s shoulder, relaxed and comfortable like best friends, with her face clearly visible beside <<<image_1>>>'s head. Both look into the lens with dead-serious straight faces, lips pressed together, eyes steady, like an ID photo.
WORLD AND SPATIAL BLOCKING
They sit at one of the long desks in a middle row, facing the front of the hall, <<<image_2>>> just behind and beside <<<image_1>>>; the phone camera looks back at them from the front. Behind their heads, the empty rows of desks and seats rise in steps toward the back of the hall, softly out of focus, with the bright windows and green trees toward screen-right. Keep the hall consistent with <<<image_3>>>; the tight selfie framing crops most of it. No other students anywhere in the hall.
<<<image_1>>> holds the phone throughout. <<<image_2>>> has both hands free to perform the sweeps around <<<image_1>>>'s face. Keep their front-to-back arrangement the whole time.
SHOT FORMAT
One continuous 10-second vertical 9:16 selfie take. The selfie image fills the whole vertical frame, with extra headroom above <<<image_1>>>'s head for the hand movements. No cuts, no external view of them filming.
OPTICS AND CAMERA
Natural front-camera perspective at arm's length, both faces readable. The camera stays almost stationary during the gag, with only slight natural hand drift. During the final laughter, allow a small believable wobble from <<<image_1>>>'s shaking shoulders while keeping both faces in frame. No zoom, no orbit, no reframing.
ACTION / PERFORMANCE TIMING
<<<image_2>>> reproduces the reference's rapid alternating hand sweeps from 0.75s to 9.0s, exchanging the upper and lower hand positions, with the same sweep directions and pace as <<<video_1>>>. She is an energetic girl deliberately holding a poker face: her face stays completely straight until 9.0s, with only her bright eyes showing she is holding back a laugh.
From 0.75s to 9.0s, <<<image_2>>>'s hands pass across <<<image_1>>>'s face about five times per second, every 4 to 5 frames, exactly at the pace of <<<video_1>>>. EVERY single hand pass reveals a different face: her expression changes behind each passing hand, about every 0.2 seconds, so the faces flicker by rapid-fire like a flipbook. Each face is big, clear and fully formed the instant the hand clears. Consecutive faces are opposites in mouth shape and eye opening (closed mouth then open mouth, wide eyes then shut eyes), so every reveal is a jolt.
PART 1 — SERIOUS
0.00–0.75s (frames 0–17): both girls dead serious, looking straight into the lens, not a hint of a smile. <<<image_2>>> raises one open hand above <<<image_1>>>'s head and places the other below her chin.
PART 2 — RAPID-FIRE FACES (starts with funny faces, builds into anger)
Two faces in each half second, one per hand pass, in this order:
0.75–1.25s (frames 18–29): cross-eyed with both cheeks puffed like a balloon → a huge wide-open toothy grin.
1.25–1.75s (frames 30–41): tongue stuck out to one side with one eye shut → eyes and mouth stretched wide in a shocked "O".
1.75–2.25s (frames 42–53): lips pushed far forward and twisted sideways → a wailing cry face, mouth pulled down, eyes squeezed.
2.25–2.75s (frames 54–65): lower jaw jutting out, eyes half-lidded → a sparkly idol smile with a wink.
2.75–3.25s (frames 66–77): nostrils flared, eyebrows shot up to the hairline → a sulky pout with puffed lower lip.
3.25–3.75s (frames 78–89): eyes rolled up to the ceiling, mouth hanging open → a smug, one-sided grin.
3.75–4.25s (frames 90–101): cheeks sucked in like a fish → an excited silent scream, mouth wide.
4.25–4.75s (frames 102–113): eyes closed, head drooping as if dozing → eyes popping wide, startled.
4.75–5.25s (frames 114–125): lips rolled in over the teeth → a big beaming grin.
5.25–5.75s (frames 126–137): an ugly sobbing face → a dreamy, melting bliss with eyes closed.
5.75–6.25s (frames 138–149): cross-eyed with the tongue tip touching her upper lip → nose wrinkled in disgust, "ew".
6.25–6.75s (frames 150–161): cheeks puffed tight → a sharp gasp, eyebrows high.
Now the faces turn from funny to cross, getting angrier with every pass:
6.75–7.25s (frames 162–173): a suspicious side-eye squint → a flat, unimpressed blank stare.
7.25–7.75s (frames 174–185): an exasperated eye-roll → an irritated frown, lips pressed hard.
7.75–8.25s (frames 186–197): narrowed glaring eyes → teeth clenched, a low growl face.
8.25–9.00s (frames 198–215): FULL FURY, the final and strongest face — eyes blazing wide in a fierce glare straight into the lens, eyebrows slammed down and together, nose wrinkled, teeth bared and clenched. She holds this fury through the last few hand passes, and it looks even fiercer after each one.
Negative for 0–9s: no talking, no smiling on <<<image_2>>>, no two consecutive reveals with the same face, no face changing while it is visible, no laughing before 9.0s, n
