Workflow
- Summarize the Story & Concept โ Defined the concept as a promotional trailer for a mystery/detective novel. Outlined the story, characters (a detective and a cat who helps solve the case), and the visual theme (flat 2D illustration, navy/brick-red/cream/mustard palette).
- Plan the Shot List โ Planned the story out into an 11-shot list.
- Generate Images via Claude MCP + Magnific โ Generated all 11 shot images through Claude connected to the Magnific MCP, using the Seedream 5.0 Pro model.
- Write Multi-shot Video Prompts โ Requested video generation prompts from Claude, split into 3 continuous clips (Shots 1-4, 5-8, 9-11), with transitions designed to connect each shot smoothly, ending each clip on a green screen for splicing together later.
- Composite in After Effects โ Brought the generated video clips together, keyed the green screens to splice them into one timeline, added a film grain overlay across the whole composition for a risograph print look, and added CTA text near the end before the book cover reveal.

Image 1 โ Opening (City Skyline)

Flat 2D painterly illustration of a rain-soaked city street at dusk, matching the exact color palette and rendering style of the reference image (deep navy blue, brick-red, cream, mustard-orange, charcoal-black). Full scene: moody sky with bold color-block clouds at the top third, a varied city skyline silhouette with mustard-orange and brick-red rooftop accents in the middle third, and foreground street elements (a vintage lamp post, a building facade edge, a hanging shop sign) framing the left and right edges in the bottom third. Thin diagonal rain streaks throughout, soft painterly gradients, clean flat color blocks, orthographic flat perspective, editorial poster illustration, noir mystery book-trailer mood. Open negative space in the center for a silhouette figure to walk through later. No text, no people, no oversized or distorted figures at the frame edges.Image 2 โ Split-screen (Wealthy House / Neon Alley)

Flat 2D painterly illustration, noir mystery book-trailer mood, matching the exact color palette and rendering style of the reference image (deep navy blue, brick-red, cream, mustard-orange, charcoal-black), split-screen composition divided by a hard vertical line down the center. LEFT HALF: an imposing wealthy family house at night, completely dark, no lights in any window, tall iron gate silhouette in front, deep navy-black tones, rain streaking down. RIGHT HALF: a narrow nightlife alley glowing with neon signage in brick-red and mustard-orange, wet pavement reflecting the lights. Bold flat color-block illustration style, soft painterly gradients, clean flat shapes, orthographic flat perspective. No text, no visible human faces, no oversized or distorted figures at the frame edges.Image 3 โ Cat Connects Two Scenes (hook)

Flat 2D painterly illustration, noir mystery book-trailer mood, split-screen composition divided by a hard vertical line down the center. LEFT HALF: an imposing wealthy family house at night, completely dark, no lights in any window, tall iron gate silhouette in front, deep navy-black tones, rain streaking down. RIGHT HALF: a narrow nightlife alley glowing with neon signage in brick-red and mustard-orange, wet pavement reflecting the lights. A single orange tabby cat is shown mid-stride crossing the vertical dividing line at the center of the frame, its front half emerging from the left (house) side and its back half still in the right (alley) side, visually stitching the two halves together as if the same cat links both locations. Bold flat color-block illustration style, soft painterly gradients, clean flat shapes, orthographic flat perspective. No text, no visible human faces.Image 4 โ Investigation Corridor

Flat 2D painterly illustration, noir mystery book-trailer mood. Two silhouette figures, a tall man and a shorter woman, walking side by side into a deep orthographic corridor with repeating door-frame arches receding into the distance, strong one-point perspective, deep navy and charcoal tones. An orange tabby cat walks ahead of them down a side path branching off the corridor, as if leading somewhere else. In the foreground, partially overlapping, a large investigation corkboard is visible with scattered case photos and a few strands of red thread just beginning to connect two clusters of pins. Bold flat color-block illustration style, soft painterly gradients, clean flat shapes, orthographic flat perspective. No text, no visible faces.Image 5 โ Case Files Close-up

Flat 2D painterly illustration, noir mystery book-trailer mood, close-up composition. Two case-file folders lying open side by side on a wooden desk, viewed from a top-down orthographic angle. Each folder page has simple labeled sections rendered as flat shapes: a section for fingerprints and a section for a hair sample, both sections rendered completely blank and empty, stark and conspicuous against the otherwise filled page. A pair of silhouette hands rests at the edge of the frame near the folders. Deep navy and brick-red accents on cream paper tones, dramatic single overhead light source creating a spotlight pool on the desk, the rest of the frame falling into charcoal-black shadow. Bold flat color-block illustration style, soft painterly gradients, clean flat shapes, orthographic flat perspective. No readable text, no visible faces.Image 6 โ Pinboard Montage (hook: Untouched Valuables)

Flat 2D painterly illustration, noir mystery book-trailer mood, dynamic montage composition. A large investigation corkboard filling the frame, covered with scattered crime-scene photographs pinned in a fast, overlapping arrangement suggesting rapid motion. One photo near the center has a bold red circle drawn around a wristwatch and a gold necklace still sitting untouched at a crime scene, with a small hand-drawn scribble mark beside it. Another photo has a bold red circle around a tiny cat silhouette caught in the corner of the frame. Dense red string crisscrosses between clusters of pins across a city map pinned beneath the photos, more tangled and thick than before, suggesting the case has grown. Deep navy, brick-red, and mustard tones on cream paper. Bold flat color-block illustration style, soft painterly gradients, clean flat shapes, orthographic flat perspective. No readable text, no visible faces.Image 7 โ Night Stakeout (hook: Two Unrelated Victim Groups)

Flat 2D painterly illustration, noir mystery book-trailer mood. Interior view from inside a parked car at night, seen through the rain-streaked windshield which distorts streetlight glow into soft glowing streaks. A tall male silhouette sits in the driver's seat, an orange tabby cat sits calmly on the passenger seat beside him, both facing forward looking out through the windshield in the same direction. On the dashboard, two photographs are held side by side by the man's silhouette hand: one showing a wealthy elderly figure, one showing a young woman, as if comparing the two victim groups for a hidden connection. Deep navy and charcoal tones dominate, with warm brick-red and mustard streetlight glow bleeding through the windshield. Bold flat color-block illustration style, soft painterly gradients, clean flat shapes, orthographic flat perspective. No readable text, no visible faces.Image 8 โ Near Miss

Flat 2D painterly illustration, noir mystery book-trailer mood, tense dramatic composition, matching the exact color palette and rendering style of the reference image. A dark narrow alley at night, rain falling. A tall silhouette figure in a raincoat is caught mid-motion slipping around a corner into deep shadow, just barely escaping. A police flashlight beam sweeps across the frame from the opposite direction, its bright warm-white cone of light illuminating the empty space where the figure was a split second earlier, narrowly missing him. An orange tabby cat is shown mid-yowl on a nearby ledge, mouth open in an alarmed cry, too late to matter. Deep navy-black shadows dominate, with a stark warm-white flashlight beam cutting through as the main light source. Bold flat color-block illustration style, soft painterly gradients, clean flat shapes, orthographic flat perspective, high dramatic tension. No readable text, no visible faces.Image 9 โ Media Pressure (hook: Censoring the word "serial killer")

Flat 2D painterly illustration, noir mystery book-trailer mood, matching the exact color palette and rendering style of the reference image (deep navy blue, brick-red, cream, mustard-orange, charcoal-black). Simple, clear composition: a television news reporter silhouette stands mid-broadcast holding a microphone, mouth open mid-sentence, framed centrally against a cream-colored building backdrop with a rain-streaked navy sky above. A bold hand-drawn black scribble mark visually redacts a portion of the on-screen caption area in front of the reporter, as if a word was struck out mid-broadcast. Rain falls throughout. No crowd, no other figures, no readable text, no visible face, no oversized or distorted figures. Bold flat color-block illustration style, soft painterly gradients, clean flat shapes, orthographic flat perspective.Image 10 โ Reveal Shot

Flat 2D painterly illustration, noir mystery book-trailer mood, matching the exact color palette and rendering style of the reference image (deep navy blue, brick-red, cream, mustard-orange, charcoal-black). A single silhouette figure wearing a mustard-yellow raincoat, turned to face the camera, walking toward the viewer through a dark corridor of flashing camera lights. His hands are held together in front of him, visibly bound by handcuffs. His face is a plain solid charcoal-black silhouette shape with no facial features at all, same flat silhouette style as other figures in this series โ no flash glare or light effect on the face itself. The camera flashes are rendered as soft bursts of warm cream-white light radiating from both sides of the frame in the background, against a deep navy-black backdrop, creating a chaotic media-scrum atmosphere, but the flashes stay off to the sides and do not wash out or overlap the figure's face. The figure's silhouette is solid charcoal-black except for the mustard-yellow raincoat and the glint of the handcuffs. Bold flat color-block illustration style, soft painterly gradients, clean flat shapes, orthographic flat perspective, dramatic high-contrast composition. No text, no other identifiable figures, no oversized or distorted shapes.Image 11 โ End Card (Book Cover / Promo Key Art)

Photorealistic minimalist book promotional key art. A single hardcover book stands upright at a slight leaning angle, resting on a floor that meets a solid flat deep navy-blue wall backdrop (hex #1D3557). Dramatic single-source side lighting rakes across the scene, casting a long dramatic shadow of the book across the floor. Clean empty floor, no props. The book cover artwork (facing the camera) is a flat 2D painterly illustration: a rain-soaked city street at night, a silhouette figure in a mustard-yellow raincoat facing the viewer with hands bound in handcuffs, face a plain black silhouette, rendered in navy/brick-red/cream/mustard tones. Bold clean sans-serif title text "THE RAINCOAT" is printed across the upper portion of the book cover in cream-white letters, with a short tagline in smaller mustard-orange text beneath it: "One yellow raincoat. The one thing this whole city will never forget." followed by a CTA line "Find the answer today โ at leading bookstores nationwide." and the "StoryBooks" imprint. Sharp product photography lighting, shallow depth of field, the book in crisp focus.Video Generation Prompts

Images used: Image 1, Image 2, Image 3, Image 4




Flat 2D color-block illustration style throughout, exact color palette locked to the reference: deep navy blue (#1D3557), brick-red (#B33B3B), cream (#EDE4D3), mustard-orange (#D98E3F), charcoal-black (#101010). No camera shake, no warping or morphing of character/object proportions, no style drift between shots. Any on-screen lettering uses a bold clean flat sans-serif in cream-white, matching the same typeface style as the book cover title โ no serif fonts, no gradient text, no 3D text effects.
Shot 1 (0:00โ0:02): Static wide shot of a rain-soaked city street at dusk with a slow push-in. Continuous diagonal rain falls, clouds drift slowly. Bold flat-color letter shapes spelling "THE RAINCOAT" slide into frame from the left edge in horizontal color-block bands (alternating navy and brick-red backgrounds behind cream letters), stacking into place until the full title is visible and holds for a beat.
Transition (0:02โ0:025): the camera rapidly zooms in toward the buildings in the middle-distance of the street, arriving within half a second at a close framing of a single building facade filling the right half of the frame.
Shot 2 (0:025โ0:045): that building resolves into the right half of a split-screen composition โ a dark wealthy house behind an iron gate, completely still, rain falling. Simultaneously the left half of the frame slides in from off-screen-left, revealing a narrow alley glowing with flickering neon signage. A female silhouette walks steadily across the neon-lit left half. Rain falls on both halves.
Continuous action (0:045โ0:065): an orange tabby cat enters from the left edge of frame and walks in one smooth continuous stride diagonally across the seam dividing the two halves, fully crossing into the right (alley) side, no cut.
Transition (0:065โ0:07): as the cat continues past the right edge of frame, the camera pans and pushes forward in the same direction of the cat's motion, carrying momentum directly into the next scene.
Shot 4 (0:07โ0:095): the camera arrives in a deep one-point-perspective corridor, dollying slowly forward as two silhouette figures (a tall man, a shorter woman) walk deeper into it; the same cat is seen leading ahead before peeling off down a side path. A foreground investigation corkboard with red thread has a subtle parallax sway as the camera moves past it.
Final transition (0:095โ0:10): as the camera continues its forward dolly, it passes through the last archway of the corridor. The dark negative space inside that final archway smoothly shifts color from deep charcoal-black to solid flat green (hex #00FF00) over the course of the movement, as if the doorway itself leads into the green space โ a continuous, motivated color-morph rather than a hard cut. By the time the camera fully passes through the archway, the entire frame holds on flat solid green, static, for the last beat of the clip.Video 2 โ Shots 5-8 (Digging Deeper โ Near Capture)
Images used: Image 5, Image 6, Image 7, Image 8




Flat 2D color-block illustration style throughout, exact color palette locked: deep navy blue (#1D3557), brick-red (#B33B3B), cream (#EDE4D3), mustard-orange (#D98E3F), charcoal-black (#101010). No camera shake, no warping or morphing of character/object proportions, no style drift between shots. Any on-screen lettering uses a bold clean flat sans-serif in cream-white, matching the book cover title typeface.
Shot 5 (0:00โ0:02): Frame opens in near-total darkness. A sudden bright flash of warm yellow light snaps on, illuminating the two open case files. A pair of silhouette hands flips through both files back and forth rapidly, comparing pages. Red handwritten-style annotation labels snap onto screen next to the empty sections: "FINGERPRINTS: NONE" and "HAIR: NONE", followed by "NO TRACE OF THE KILLER" stamped below.
Transition (0:02โ0:025): the orange circular vignette framing the case files throughout shot 5 contracts smoothly inward, tightening into a smaller red circle โ landing exactly as the red circle drawn around a wristwatch and necklace on the investigation corkboard.
Shot 6 (0:025โ0:045): the camera whips and zooms rapidly between individual pinned photos on the corkboard in quick continuous succession, red string snapping taut between pin clusters. The handwritten label "NOTHING TAKEN?" snaps onto screen beside the circled watch and necklace.
Transition (0:045โ0:05): quick whip-cut into the car interior.
Shot 7 (0:05โ0:075): Inside a parked car, rain falls outside the windows. The cat sits on the passenger seat looking out the window, ears perking up. The cat suddenly yowls and leaps out through a gap in the window. The man scrambles out of the car, grabs a flashlight, and runs after the cat โ quick whip-cuts between 2-3 dynamic angles (side tracking view, low-angle running view), bold motion speed-lines trailing both the man and cat as they sprint into a narrow alley. Fast, urgent pacing throughout.
Shot 8 (0:075โ0:095): the cat chases ahead of the man toward a cloaked figure fleeing deeper into the alley. The flashlight beam swings and catches a brief glimpse of the fleeing figure โ then he's gone, vanished into the dark. The man and the cat both stop, turning to look at each other in a shared beat of realization. Hold this look for a full extra beat; rain intensifies slightly during the pause.
Final transition (0:095โ0:10): the flashlight beam in the man's hand widens and swells to fill the entire frame, its warm yellow-white light smoothly shifting color into solid flat green (hex #00FF00) as it takes over the screen completely, holding static for the last beat.Video 3 โ Shots 9-11 (Pressure โ Reveal โ Cover)
Images used: Image 9, Image 10, Image 11



Flat 2D color-block illustration style throughout, exact color palette locked: deep navy blue (#1D3557), brick-red (#B33B3B), cream (#EDE4D3), mustard-orange (#D98E3F), charcoal-black (#101010), transitioning into photorealistic product photography only for the final shot. No camera shake, no warping or morphing of proportions. Any lettering uses bold clean flat sans-serif in cream-white, matching the book cover typeface.
Shot 9 (0:00โ0:02): Slow push-in on a news reporter silhouette mid-broadcast, mouth moving continuously, microphone bobbing slightly. A bold black scribble/redaction mark flickers on and off over the caption area, its flickering frequency accelerating steadily faster as the shot progresses. Continuous rain falls throughout.
Transition (0:02โ0:025): the redaction mark's flicker frequency peaks into a rapid strobe, which hard-cuts directly into warm-white camera flash bursts taking over the frame.
Shot 10 (0:025โ0:055): the mustard-yellow raincoat silhouette walks steadily forward toward the camera down a corridor. Camera flashes strobe rapidly and irregularly from both sides throughout. His cuffed hands swing gently with his walking rhythm. His face stays a plain flat black silhouette with no flash glare on it. Building tension as he approaches.
Transition (0:055โ0:07): at the closest point, without freezing, the camera begins a continuous smooth zoom-out/dolly-back. As it pulls away, the edges of the frame reveal themselves to be the border of a physical book cover.
Shot 11 (0:07โ0:095): the zoom-out continues until the full book is revealed, standing upright at a slight angle on a dark navy tabletop, its cover showing the frozen raincoat image with the title "THE RAINCOAT" at the top. Photorealistic product lighting, a soft dramatic shadow, faint atmospheric haze drifting in the background.
Final hold (0:095โ0:10): camera settles to a complete static hold on the book, no further movement.Suno Prompt
