Snorricam

Camera and lensCamera clause

subject_definitions:
<Subject 1> is the young woman in <Picture 1>: long light brown wavy hair, fair freckled skin, round gold-rimmed glasses, wearing a simple white slip dress with thin straps. Her exact facial structure, features and proportions stay identical to <Picture 1> in every frame.

summary:
[reference generation] The target video shows <Subject 1> running through a crowded indoor house party from room to room, in a head-and-shoulders close-up from just below her eyeline, as the camera performs a snorricam shot.

retention_analysis:
<Subject 1> (appears in [Shot 1]): fully_preserved - her face, identity and clothing are held identical to <Picture 1> in every frame with zero drift.

detailed_description:
The target video is live-action and cinematic, shot on an ARRI Alexa Mini with a 14mm wide prime, the camera fixed rigidly to her torso so it moves exactly with her body, harsh mixed party lighting with warm tungsten sconces and coloured LED wash spilling from open doorways sweeping hard across her face as she passes each one, a rich saturated palette with deep shadow.
[Shot 1] A head-and-shoulders close-up of <Subject 1>, framed from just below her eyeline a short distance in front of her and angled gently upward at her face, shows her whole head and both bare shoulders with a clear margin of open space above her hair, so that the top of her head never reaches the top of the frame, as she is running hard down a narrow, packed indoor corridor at a house party and banking round its corners into the rooms off it, her hair flying and the thin straps of her dress shifting with every stride, with people crushed shoulder to shoulder along both walls with drinks, shouting over the music, open doorways spilling coloured light ahead of her, a low ceiling strung with warm bulbs close overhead, and each room she banks into more congested than the last. <Subject 1> runs hard down the corridor and banks hard round each corner and through each doorway into the next crowded room, carried forward at the same speed from the first frame to the last, never breaking stride. Her shoulders and chest stay frozen in the frame throughout: they hold exactly the same place at exactly the same size in every single frame, never drifting a pixel, and her head is the only part of her that moves inside that frozen frame. Everything else is thrown onto the world. Tracking with her at fast speed and shaking strongly with large amplitude, the whole party - the ceiling lights, the door frames, the packed bodies pressed in on both sides - heaves and drops in exact time with her stride, and each time she banks into a turn the entire room whips sideways across the frame in one fast pan, the walls and the crowd sweeping past the lens fast enough to smear into streaks before the next room opens up ahead of her. <Subject 1> is already wide-eyed and frightened in the very first frame, her brows pulled up and together and her eyes stretched wide, and the fear only tightens as she runs: her stare fixes harder, her brows draw in further, and her breathing grows faster and more ragged through her nose. Her lips stay pressed together the whole way, the breath forced out through her nose. Her head rocks with the impact of every stride while her shoulders stay locked in place, and both arms swing freely and loosely at her sides in rhythm with her run, her hands open and relaxed.

overall_soundscape: Her footfalls and breathing stay close, loud and constant, right up against the microphone, her breath tightening into a fast ragged hiss through her nose as the shot goes on, while the party swings and lurches around her with every stride, the music and shouting swelling hard as she banks into each new room and sweeping away behind her.

non_diegetic_music: A relentless two-note pulse locked exactly to her stride, one hit per footfall, never speeding up or slowing down, with a high thin dissonance creeping in above it and tightening as the shot goes on.
