A minimalist single-line flat-vector animation depicts a journey from a sudden idea, represented by a lightbulb, to browsing a website, connecting with a service provider, and completing a home project.
Create a 16:9 horizontal screen business explainer animation in a flat single-line hand-drawn style. The overall style: an off-white paper background #F2F0E4 fills every scene (the background is always this off-white, no gray or gradient backgrounds allowed). All characters, furniture, interfaces, and icons are outlined with a single extremely thin dark charcoal gray line, with consistent line width, as if drawn on paper with a 0.3mm technical pen. Only one accent color is allowed throughout the film: lemon yellow #EDE04A, used for character pants, web highlight bars, lightbulbs, shields, and map color blocks. Yellow is a pure flat color, no outlines or color overflow. No gradients, no shadows, no texture grain. The screen has a lot of white space, with only one main visual subject and two or three small props per scene. The composition is always centered slightly below, leaving breathing room at the top. There are two fixed characters whose appearance must be completely consistent throughout the film: Character A is a young man with curly hair, represented by seven or eight spiral lines, dot eyes, a white long-sleeved shirt (outlined only, not filled), lemon yellow trousers, and black single-line shoes. Character B is a craftsman wearing a baseball cap with the brim forward, a beard represented by short arcs, overalls entirely filled with lemon yellow, and two clear straps on the chest. The rhythm is fast-paced but not chaotic, with clean horizontal wipes or element pop-up transitions between shots. The camera remains completely still within each shot. The shots are as follows: Shot 1 (Opening Hook): Character A is initially slumped on a single-line outlined two-seater sofa (the sofa has rounded armrests, three clear seat cushions, and a small three-tier side table with two books). Suddenly, he springs up straight, and a large lemon yellow lightbulb pops up above his head with a 'bang'. The lightbulb magnifies to occupy the top third of the screen, with its filament drawn as a small lightning bolt symbol, accompanied by two radiating short lines when it pops up. Shot 2: Cuts to a desk scene. Character A sits at the desk, with an open laptop on it. A line-art web browser window pops up on the screen: a top address bar, three small dots on the top left, and a rectangular banner in the middle filled with lemon yellow. A cursor arrow quickly clicks twice, and the window slightly compresses and rebounds with each click. Shot 3: A dozen small lemon yellow squares fly out of the screen, connected by thin straight lines to form a continuously expanding net-like structure in the air. The nodes of the net light up yellow one by one, and the entire net gently undulates as if breathing. Shot 4: The line net contracts and disappears. Character A slides in from the left side of the screen, and Character B slides in from the right, carrying a paint roller. They stop in the center, look each other up and down, lean forward slightly, and small question marks pop up above their heads and quickly dissipate. Shot 5: A lemon yellow shield with a checkmark pops up between them. After the shield settles, they shake hands, and three short emphasis lines pop up at the handshake point. Shot 6: Cuts to a whiteboard hanging on two thin lines. Three line-art icons pop up one by one from left to right on the whiteboard: a single person icon, a shield, and a piggy bank (pig-shaped with a coin slot). Each icon enters by first enlarging by ten percent, then rebounding to its original size. The two characters stand small below the whiteboard, looking up. Shot 7: A line-art wallet is centered. A padlock falls onto the wallet from above, and the shackle clicks shut. At the moment of locking, four short lines pop up on both sides of the wallet, indicating vibration. Then the lock body is filled with lemon yellow. Shot 8: Cuts to a corner of a room. Character B stands on a step stool, painting a wall with a roller. As the roller moves, the entire wall section instantly turns lemon yellow. Three strokes are painted, with the color appearing immediately after the roller. A line-art paint bucket is on the floor. Shot 9: Cuts to a single-line world map. Lemon yellow color blocks start from a point in Europe and quickly spread like ink stains to all continents. Simultaneously, seven or eight small icons pop up one by one at various locations on the map: a wrench, a roller, a lightbulb, a house. Each icon is accompanied by a circle of small bubbles. Shot 10 (Ending): A line-art laptop is centered and magnified. A lemon yellow shield with a checkmark pops up on the screen. Below the shield, a black sans-serif uppercase short word "DONE" pops up in a yellow horizontal bar, with slightly wide letter spacing. Then the entire screen gently floats up and freezes. All elements enter with elastic overshoot (first exceeding ten percent, then rebounding) and exit cleanly without lingering. At no point should there be more than five elements on screen. AUDIO: Please generate a brand new original, royalty-free instrumental background music as the base track (not an existing song or famous melody), and pair it with a warm, friendly, and fast-paced English male voice-over, synchronized with the screen rhythm, clearly and naturally narrating: "Painting your walls? Stop hunting for the right worker. On this platform you reach trusted service providers directly, with no middlemen and no overpaying. Smart contracts protect every deal: your payment waits safely in escrow, and only when the job is done and you are happy is the money released. Fast, safe and fair, the easiest way to get your home projects done." The voice-over must be natural and fluent and finish before the end of the video. No other human voices besides the voice-over. Music volume should be lower than the voice-over. No Chinese throughout the film. The only readable text allowed on screen is the word "DONE". No real brand names, URLs, logos, or watermarks. Prohibitions: gradients, photo materials, realistic rendering, camera shake, camera push/pull, gray background, two simultaneous focal points on screen.
