Frame Break Effect: Anime Character Climbs Out of the Letterbox (Pika H3 Flex)

References: @[char ref]: Rin, shown on a character turnaround sheet. Messy short black bob, olive-brown eyes, gold drop earrings, thin gold necklace with an oval pendant, cream camisole slip dress, oversized off-white button shirt worn loose off the shoulders, bare feet. Take her identity, outfit, expressions, and clean anime line style; render one normal scene, never the sheet layout, its grey backdrop, or several copies of her. @[letterbox ref (attached image)]: the letterbox composition only: a pure white central picture area between two thick, solid black horizontal bars at the top and bottom of the 16:9 frame. Visual style: Clean 2D anime, crisp line art, soft cel shading, bright and playful. The central area is pure white, a seamless empty space with a soft floor shadow under Rin to show depth. Strong foreshortening whenever she comes close to the lens. Bouncy, elastic comedy acting with springy hair and fluttering shirt. Avoid: No subtitles. No music. No glitches, static, or VHS effects. No cuts, zooms, or camera movement. No vertical borders or picture frames. Rin, goofing around alone in an empty white space, notices she is being watched and climbs out over the letterbox toward the viewer. One continuous locked-off wide shot at eye level, no cuts, about 15 seconds. The two black bars never move, bend, flicker, or change; they behave like solid flat bars printed on the screen. At the start Rin is entirely inside the white area, behind the bars; as she comes forward, the parts of her that cross the lower bar are drawn in front of it, overlapping the black, for a pop-out illusion. Sound: soft room tone, bare footsteps, a belly-slide squeak, a tap on glass, giggles, a soft thump. No dialogue. Scene 1: Continuous, the white letterbox space. Shot 1 (0-15s): Wide shot, eye level, locked-off camera for the whole clip. From 0 to 3 seconds, Rin is small and far away in the center of the white area, full body, facing the lens. She does a silly noodle dance: floppy wobbling arms, hip wiggles, head bobbing, the loose shirt flapping. From 3 to 5 seconds, she spots the viewer, gasps happily, and skips straight toward the lens, growing larger. Her bare foot catches, she pitches forward and slides on her belly the rest of the way, stopping with her face just above the inner edge of the lower bar, still fully inside the white area. From 5 to 8 seconds, the frame break begins. Her right hand slaps down onto the lower bar and is drawn in front of the black, fingers spread over it. Her left hand follows. She pulls herself up and props both forearms on the lower bar like a windowsill, forearms and elbows in front of the black, rests her chin on her stacked hands, and grins at the lens. Behind her, inside the white area, her bare feet kick lazily in the air. From 8 to 11 seconds, she leans further out over the lower bar, head and shoulders now in front of the black and large in the foreground. She reaches toward the lens and taps it once with her index finger, as if it were glass. Then she puffs her cheeks and squishes one cheek flat against the lens; her breath fogs a pale cloudy patch on it. From 11 to 13 seconds, she pulls back slightly, still leaning over the bar, and draws a smiley face in the fog with her fingertip, giggling. From 13 to 15 seconds, she waves at the viewer eagerly with both hands, loses her grip, and slides backward behind the lower bar, disappearing below its edge with a soft thump. Only her right hand stays up in front of the black bar, still waving, when the clip cuts to black.
