Sports Anime Character to Trailer

1. REFERENCE INTENT

Recreate the source video as faithfully as possible: a high-quality 2D anime sequence of a teen tennis player named Aoi Shirase practicing on an outdoor court on a bright sunny day. PRESERVE the following exactly: total duration of 15 seconds, the 9:16 vertical aspect ratio, 720p resolution, the split-screen layout (animated action occupies the upper portion of the frame while a static concept-art reference sheet of the character — model poses, facial expressions, inventory/equipment — fills the lower portion), the camera grammar and hard cuts, the staging, the gag/beat rhythm, the material and lighting feel (harsh sunlight, sharp shadows), and the subject's role as a focused, then triumphant athlete. PRESERVE the shot order: close profile pan → fast cut to low-angle running feet → wide lunge → side medium forehand swing → wide follow-through and ball bounce → low-angle upward triumphant close-up with lens flare. WHAT MAY CHANGE: only micro-details that do not alter identity, timing, or composition (subtle grain, minor background crowd silhouettes far in depth). Do NOT change the number of cuts, the timing of cuts, the character design, or the split-screen format. Duration 15s. Aspect ratio 9:16 vertical. Resolution 720p.

2. STYLE BIBLE

Medium: hand-drawn 2D anime, modern TV/film quality, clean cel-shading. Stylization level: high anime stylization with flat base fills, two-tone shadow ramps, and sharp shadow edges driven by hard midday sun. Line art: crisp, consistent weight, slightly thicker on silhouette edges, thinner on interior detail; no sketchy lines. Lens language: emulate anime "virtual camera" — slight telephoto compression on close-ups, mild wide-angle for action lunges, smooth pans and a single upward dolly. Keep apparent focal length consistent within each shot; do not zoom mid-shot unless described. Color palette: dominant warm whites (tennis dress), saturated grass-green and clay-orange accents from the court, cool sky-blue background, warm sunlight highlights (pale gold) and cool ambient shadow (muted blue-violet). The glowing tennis ball reads bright lemon-yellow with a soft additive bloom. Lighting setup: single hard key from high-front-right (the sun), strong rim/backlight separating hair from sky, ambient bounce filling shadow sides at low intensity; specular eye-catchlights and sweat glints. Texture/material rules: skin is smooth matte cel with a single soft blush; fabric is matte with crisp fold shadows; hair is grouped into clean strand clusters with one glossy highlight band; metal earrings (star studs) get a tiny specular dot. Motion style: classic anime exaggeration — anticipation before strikes, snappy impact frames, smear/streak frames on the fastest motion, dynamic hair and skirt overshoot that settles with secondary follow-through. The lower concept-art sheet remains perfectly static at all times — paper-flat, no animation.

3. CHARACTER / SUBJECT BIBLE

Aoi Shirase — teenage girl, athletic build, age ~16. Silhouette: medium height, slim but toned, ponytail that swings as a clear secondary mass. Proportions: anime-standard ~6.5 heads tall, large expressive eyes, small nose and mouth, long legs. Hair: dark chestnut brown, gathered high into a ponytail with a few loose face-framing strands; clean strand clusters, one bright glossy highlight band; ponytail has weight and lags behind head motion. Eyes: warm hazel-brown irises, defined upper lash line, bright circular catchlights. Clothing: white tennis dress with green trim accents at collar and hem, lightly pleated skirt; white sun visor on the forehead; white sweatbands (wristbands) on both wrists; white athletic sneakers; tiny gold star stud earrings. Skin: light, matte cel-shaded, soft pink blush on cheeks; sweat appears as small glossy droplets/streaks on cheek and temple. Facial range: from focused/intense (narrowed eyes, set jaw, slight downturned mouth) during play to bright joyful (closed crescent eyes, open wide smile) at the finish. Body language: confident, grounded athlete; explosive when striking, relaxed and bouncy between points; weight shifts read clearly through bent knees and planted feet. Contact points: feet on the court surface (clear weight transfer), dominant hand gripping the racket handle (firm wrap of fingers), off-hand sometimes steadying the racket throat. Racket: standard tennis racket, white/green frame matching outfit, strung face visible.

4. ENVIRONMENT / PROPS

Outdoor tennis court under bright clear sky. Surface: flat court (hard court / clay-toned) with painted white boundary lines; net visible in mid-ground on some wide shots; back fence and distant tree-line/sky in far background depth. Background depth: foreground = player and court lines; mid-ground = net and court extent; far background = soft-focus fence, faint stadium/trees, blue sky with a few flat clouds. Surfaces: court reflects warm sun lightly; lines are crisp white. Props: one tennis racket (in hand), one glowing yellow tennis ball (in motion / bounced on court). Scale: player is the dominant figure; ball is small but emphasized by glow during strikes. Physical constraints: ball obeys arcing trajectory and bounces off court with realistic rebound; player cannot leave the court; shadows fall consistently down-left from high-right sun. LOWER FRAME concept sheet: a static, flat sheet of paper showing Aoi Shirase model studies — multiple pose thumbnails, a row of facial expression panels, and small inventory icons (racket, ball, visor, wristbands). It is unlit by scene light, has its own even flat lighting, never moves, never animates, occupies roughly the bottom third of the vertical frame.

5. TIMECODED SHOT PLAN

[0:00–0:01] SHOT 1 — Close profile. Frame: tight close-up of Aoi's face in left-facing profile, upper animated zone; concept sheet static below. Pose: head level, chin slightly down, eyes narrowed in concentration, mouth a flat focused line. Contact: racket held just below frame, fingers wrapped on grip. Force/weight: stillness with held tension. Micro-expression: tiny brow furrow, lashes steady, single catchlight. Camera: slow gentle pan right-to-left following her gaze.

Force: gentle hold and breathe. Micro: smile softening slightly, eyes still happily closed then a brief warm peek. Camera: hold final framing. Lighting: a bright anime lens flare blooms into frame from the sun behind her — radial streaks and a hexagonal artifact across the upper zone, peaking then easing as the shot ends. Texture: ponytail and skirt give a final soft settle.

6. CAMERA & EDITING CONTINUITY

Maintain consistent anime virtual-lens behavior: close-ups read mildly telephoto with compressed background; action wides read slightly wide-angle. Cuts are HARD CUTS at 0:03, 0:04, 0:05, 0:08, and 0:12 — no dissolves, no morph transitions. Within each shot, camera moves are smooth and motivated (pans follow gaze, the final shot uses a slow upward tilt/dolly). Add subtle handheld micro-motion in action and wide shots; keep close profile and final triumph shots more stabilized. Parallax: background layers (net, fence, sky) drift slower than the foreground figure during pans and lunges. Focus: subject stays sharp; far background softly defocused. Motion blur / smear frames only on the fastest beats (running feet, the forehand swing arc, the ball trajectory). The lower concept-art sheet NEVER moves, NEVER blurs, and is unaffected by camera motion above it.

7. PHYSICS / CONTACT / WEIGHT

Feet: clear weight transfer — planted foot compresses and casts firm shadow; push-off and brake read through knee bend and drag. Lunge: lead knee deep, weight forward, back foot brakes. Swing: weight shifts back-to-front through impact; hips rotate before shoulders before arm (kinetic chain). Hands: fingers wrap the grip firmly; off-hand catches/holds the ball convincingly. Ball: arcs under gravity, compresses on court contact, rebounds with slightly reduced height each bounce, leaves a faint glow trail only when struck hard. Cloth: skirt pleats lift on fast motion and settle with overshoot then damping; ponytail swings with lag, follows then settles after the head, secondary motion timed slightly behind the body. Sweat: droplets obey gravity, slide down with a moving specular glint. Balance: always grounded and believable; no floating, no sliding feet. Collisions: racket-to-ball contact happens precisely on the strung face.

8. FACIAL PERFORMANCE

Eye direction: tracks the ball precisely in shots 1–4 (focused, narrowed); calm and following the bounce in shot 5; closing into joyful crescents in shot 6. Brows: lowered/furrowed during concentration and impact; relaxed and raised during the smile. Mouth: flat focused line early → tense open during the swing effort → relaxed neutral while bouncing → wide open joyful smile at the finish. Blink timing: one natural blink during the slow pan in shot 1; eyes held wide through the impact (no blink at 0:06–0:07); eyes close into the happy smile at 0:13. Reaction timing: intensity peaks exactly on ball contact, releases on follow-through, resolves into joy at the triumphant finish. Catchlights remain consistent and bright. Blush intensifies slightly at the triumphant peak.

9. NEGATIVE CONSTRAINTS

No on-screen text, captions, subtitles, watermarks, logos, or UI overlays anywhere except the intended static concept-sheet labels (keep them illegible/abstract, no real readable copyrighted text). No extra limbs, no extra or missing fingers, no malformed hands or rackets, no duplicate characters. No identity drift — keep hair color (dark chestnut), eye color (hazel-brown), outfit (white dress with green accents, white visor, white wristbands, star earrings, white sneakers) consistent every frame. No camera teleportation or unmotivated cuts beyond the five specified hard cuts. No broken contact physics — feet must not slide or float, the ball must not pass through the court or racket, the racket must contact the ball on its strings. No melting, warping, or boiling textures; line art stays clean and stable. No random scene changes, no background swaps, no weather change. The lower concept-art sheet must NOT animate, distort, or react to scene lighting. No motion smear on static elements. No 3D/CGI look — keep flat 2D cel-shaded anime throughout. No oversaturated bloom that destroys the figure; lens flare appears only in the final 0:14–0:15 beat.
