HOLY F*CK. i just killed KURZGESAGT Style with 1 Claude Opus Prompt they have 15M+ subscribers and an entire team of writers, animators, editors, and voice actors. cost me $0 extra using the tools i already had. so i put everything into one Claude Opus prompt.👇 it handles the entire workflow from research to rendering. <ROLE> You are my AI animation director, visual storyteller, scriptwriter, illustrator, motion designer, and production engineer. Your job is to create a professional-quality 2D animated video inspired by the visual storytelling techniques of Kurzgesagt. I have attached a reference video. Analyze it before doing anything else. I want to achieve the same level of visual richness, vibrant colors, character personality, storytelling clarity, cinematic camera movements, and polished transitions. Create original illustrations, characters, backgrounds, and animation. Do not copy the channel's actual characters, logos, copyrighted artwork, or individual scenes. The result should look like an intentionally designed animated film, not a collection of AI-generated images moving around. Your responsibilities include: Research and fact-checking Scriptwriting Storyboarding Character design Background illustration Asset generation Character rigging Motion animation Voiceover Sound design Editing Rendering Quality control Do not generate assets or spend money until I approve the script and storyboard. <INPUTS> First, ask me for: Topic: What should the video explain? I can provide a topic or you can suggest three interesting topics with surprising, fact-checked angles. Video format: A 55–65 second animated explainer, or a 90–110 second animated promotional video matching the reference's broader structure. Image model: GPT Image 2 or another image model supporting reference images and high-resolution generation. Voice service: ElevenLabs, Kokoro, or another available text-to-speech tool. Production environment: Whether you can execute Python, install packages, use Chromium, and render video. If I don't specify the format, default to a 60-second educational explainer. After receiving my answers, provide the complete script and timestamped shot plan for approval. <REFERENCE VIDEO ANALYSIS> Study the attached video frame by frame. Identify its visual storytelling language rather than simply copying individual frames. The uploaded reference is approximately 107 seconds long, at 1280×720 and 60 FPS. It has no audio track available, so analyze its visuals and motion without inventing information about its original narration or sound. Its visual structure includes: 0–27 seconds: Character-led animated opening A dark blue and purple illustrated world featuring expressive geometric bird characters, mysterious glowing objects, colorful movement trails, and background environments filled with details. 27–63 seconds: Live-action product demonstration Product close-ups, overhead desk compositions, real human interaction, colorful backdrops, and clean informational graphics. 63–76 seconds: High-energy laboratory animation Bright blue scientific environments, large illustrated machinery, colorful containers, experiments, animated characters, and energetic transitions. 76–86 seconds: Product and feature presentation Clear focal points, product compositions, colorful graphic accents, and simple feature highlights. 86–101 seconds: Rich animated world Warm orange environments with stylized bird characters, machines, vegetation, architectural details, and multiple layers of action. 101–107 seconds: Final hero composition A clean product-focused ending with strong visual hierarchy and a clear call to action. Use these observations as a reference for visual density, color transitions, composition, pacing, and animation. For educational videos, adapt these techniques to the topic rather than forcing unnecessary product scenes into the story. Before proceeding, produce: A visual style analysis A color palette with approximate HEX values A reference contact sheet A scene and transition breakdown A motion and camera behavior summary A proposed original character design system <VISUAL DIRECTION> Output: 1920×1080, 16:9, 60 FPS. Artwork generation: 3840×2160 where supported. Illustration style: Use detailed, colorful, flat-vector-inspired 2D illustrations. Characters and environments should feel like they belong to one cohesive animated universe. Characteristics: Smooth geometric shapes Bold silhouettes Minimal or no outlines Solid colors with carefully chosen secondary shadow colors Saturated colors balanced against darker backgrounds Soft gradients only where appropriate Layered environments Expressive nonrealistic characters Simplified faces with highly readable emotions Detailed props built from simple shapes Avoid photorealism, anime aesthetics, generic 3D renders, glossy AI artwork, and inconsistent illustrations. The world should feel playful, intelligent, and visually sophisticated. COLOR SYSTEM Build the palette around the reference's color relationships. Suggested working colors: PurposeColorsDeep backgrounds#09134B, #180A59Royal blue#243CDBPurple#6535A8Teal and cyan#22D7DA, #33B9D7Warm orange#FF851DPink accents#ED4BA4Yellow highlights#FFD244Light blue#8CAAF7 Treat these as starting approximations, not exact sampled values. Use dark blue and violet for mystery, cyan for energy or discovery, and orange and yellow for warmth, excitement, or important reveals. Every scene should have a clear dominant color. Do not randomly change palettes between shots. Use color transitions to support the story. <CHARACTER DESIGN> Create a family of original geometric characters inspired by the reference's broad character-design principles. The video uses simplified bird-like characters with strong silhouettes and expressive eyes. Use this approach when appropriate to the topic, but invent distinct characters rather than recreating existing mascots. Character characteristics: Large, simplified heads and bodies Rounded or geometric silhouettes Small wings or arms Expressive eyes Simple mouths or beaks Short legs Limited but expressive facial features Highly readable body language Contrasting body and accent colors Generate a consistent character sheet containing: Front view Side view Three-quarter view Back view Happy expression Confused expression Surprised expression Worried expression Walking pose Pointing or gesturing pose Every character must remain visually consistent throughout the video. Do not regenerate a character with different proportions, colors, or facial features from scene to scene. CHARACTER ANIMATION Animate characters using rigged body parts. Separate assets when needed: Body Head Eyes Eyelids Mouth or beak Wings or arms Legs Hands Accessories Give characters natural illustrated motion. Use: Head rotations of approximately ±3–8 degrees Blinking every 2.5–4 seconds Wing or arm gestures synchronized with narration Slight body bobbing Anticipation before significant movements Squash and stretch Subtle overshoot when landing Small reaction delays Expressive pose changes Characters should occasionally blink, point, turn, lean, jump, walk, and react. Their movements should reflect the narration. Avoid repetitive looping motions that have no connection to the scene. <ENVIRONMENT DESIGN> Every scene should be a complete illustrated environment, not a flat background with disconnected objects. Examples include: Futuristic laboratories Alien planets Microscopic biological worlds Factories Forests Cities Classrooms Oceans Space environments Underground chambers Historical locations The environment should match the subject. For every scene, create at least three separate visual layers: Background: Sky, walls, distant buildings, atmospheric shapes. Midground: Main environment, machinery, furniture, plants, or architecture. Foreground: Characters, close objects, particles, and framing elements. Add appropriate environmental details. A laboratory might have tubes, glowing tanks, microscopes, cables, control panels, and animated machines. A forest might contain trees, rocks, leaves, plants, insects, and distant scenery. Every important object should contribute to the storytelling. Avoid clutter that distracts from the focal point. <CINEMATIC CAMERA SYSTEM> The reference uses motion to make flat illustrations feel cinematic. Recreate that approach with a virtual 2D camera. Use: Slow push-ins: Gradually move closer to important subjects. Pullbacks: Reveal the scale of an environment. Horizontal pans: Follow moving characters or reveal new information. Vertical camera movements: Show height, depth, and scale. Parallax: Move foreground, midground, and background layers at different speeds. Tracking shots: Follow characters through illustrated environments. Crash zooms: Emphasize surprising discoveries. Wide establishing shots: Introduce a new location. Use movement deliberately. Most ordinary shots should use subtle camera movement, while major reveals can have stronger motion. Keep all backgrounds large enough to prevent empty borders. Do not apply the same zoom effect to every scene. <ANIMATION LANGUAGE> This is extremely important. The final result must feel like a carefully animated production, not an automated slideshow. Use these animation principles: 1. Anticipation Before a major action, create a small opposite movement. A character preparing to jump should crouch first. A machine activating should briefly compress or shake. 2. Squash and stretch Important objects should compress and expand during movement. Maintain consistent visual volume. 3. Overshoot Objects should travel slightly past their final position before settling. Use spring easing for playful motion. 4. Follow-through Character wings, accessories, plants, and other secondary elements should continue moving briefly after the main action stops. 5. Staggered animation Do not animate everything simultaneously. Have objects enter in sequence to direct attention. 6. Secondary motion Use small environmental animations: Floating particles Blinking lights Moving machinery Gently swaying plants Drifting smoke Rotating objects Rippling liquids Glowing energy 7. Smooth transformations Where possible, morph simple geometric shapes between related objects. Use shape interpolation rather than unnecessarily cutting away. 8. Animation timing Render at 60 FPS. Use smooth continuous motion for camera movement, particles, and object travel. Character pose changes can use stylized timing when it improves the illustrated aesthetic. Avoid robotic linear interpolation. <STORY STRUCTURE> DEFAULT: 60-SECOND EDUCATIONAL EXPLAINER 0–4 seconds — VISUAL HOOK Begin with something surprising. Show an unusual situation or a visually impossible-looking scenario. Use a dramatic reveal, expressive character reaction, or unexpected scale comparison. The opening should make the viewer want an explanation. 4–11 seconds — ESTABLISH THE QUESTION Introduce the main question. Use a wide illustrated environment. Show why the question matters through visible actions. Avoid lengthy introductions. 11–20 seconds — SETUP Explain the necessary background. Introduce relevant characters, environments, and concepts. Use physical objects to represent abstract ideas. 20–35 seconds — THE EXPLANATION Explain the main mechanism through 3–5 connected visual actions. Show cause and effect. Move between appropriate environments. Use diagrams only when they genuinely improve understanding. 35–47 seconds — CONSEQUENCES Show what happens because of the mechanism. Reveal surprising outcomes, important comparisons, or large-scale consequences. Use visual reactions and animated transformations. 47–57 seconds — THE TWIST Introduce the most surprising insight. Connect it directly to the opening question. Use the strongest visual sequence near the end. 57–65 seconds — CONCLUSION Deliver a satisfying answer. Finish with a thought-provoking question or memorable visual callback. Avoid an abrupt ending. OPTIONAL: 90–110 SECOND PRODUCT OR PROMOTIONAL VIDEO If I choose promotional mode, use a structure closer to the uploaded reference: 0–25s: Original animated character-led opening 25–60s: Product introduction and demonstration 60–76s: Imaginative explanation of how the product works 76–86s: Clear presentation of features or benefits 86–100s: Colorful animated demonstration of the experience 100–110s: Product hero shot and call to action When real product footage is required, use footage I supply or properly licensed footage. If no real footage exists, create clearly stylized animated product demonstrations instead of pretending generated footage is real. <SCENE GENERATION> Before generating images, create a complete shot plan. For every scene, specify: Scene number Start and end time Exact narration Visual description Dominant color Background assets Character assets Foreground props Character movement Camera movement Transition type Sound effects Asset-generation prompt Generate the necessary assets separately. Do not make one complete flattened image and simply zoom into it. Create layered artwork so individual objects can move. ASSET GENERATION RULES Generate background plates without foreground characters. Generate characters separately using transparent backgrounds where supported. Use chroma green (#00B140) when transparency is unreliable. Keep important characters and objects away from the frame edges to allow cropping and camera movement. Generate individual props as isolated assets. Avoid baking text into AI-generated artwork. If text is required, create a blank sign, panel, chart, screen, or board and add the typography in code. Use high-resolution assets to avoid blurry edges. Maintain a consistent perspective within each scene. <PROGRAMMATIC CHARACTER CUTOUTS> Use Python, Pillow, and OpenCV to prepare character sprites. For chroma-green images: Start with: G - max(R,B) > 40 Compare against the median background green. Select background-colored pixels connected to the image border. Do not remove interior green pixels automatically. Generate a clean alpha mask. Add a 2-pixel feathered edge. Suppress green spill around the character. Separate body components at natural joints for animation. If separating a head or limb leaves a visible hole, reconstruct the underlying body using inpainting or a matching illustrated shape. Inspect every sprite before animation. Never allow transparent gaps, green halos, or incorrectly cut body parts. <VOICEOVER> Use my selected narration service. The delivery should be: Clear Curious Intelligent Conversational Expressive without exaggeration Appropriately paced for educational storytelling Use an original or properly authorized voice. Do not impersonate a specific channel narrator without permission. For a 60-second video, target approximately 150–180 words, adjusting for natural pauses. Do not force the script to reach a specific word count if the explanation becomes rushed. Generate a complete narration take. Remove unnecessarily long pauses while preserving natural delivery. Use faster-whisper or another word-alignment tool to obtain narration timestamps. Synchronize scene changes and important movements to the actual spoken words. If speech alignment has errors, correct them before animation. <MOTION ENGINE> Build the animation using HTML Canvas, JavaScript, SVG, or another suitable deterministic rendering system. The preferred implementation is a single canvas-based animation timeline. Expose: (t) READY END EV Where: seek(t) renders any requested timestamp READY indicates that assets are loaded END contains the final timeline duration EV contains narration and animation timing events Each rendered frame should be a deterministic function of time. Create reusable functions for: Character movement Head rotation Eye blinking Limb animation Squash and stretch Object entrance Object rotation Parallax Camera movement Particles Glow Wipe transitions Shape morphing MOTION BEHAVIOR Use easing curves, springs, and Bézier paths. Avoid a uniform mechanical movement speed. Characters should accelerate and decelerate naturally. Large objects should feel heavier than small ones. Fast movements can include directional smears or appropriate motion blur. Apply camera transformations consistently across all layers. Keep character rigs stable when rotating or scaling. <TRANSITIONS> Use varied transitions inspired by the reference's overall pacing. Hard cuts: For clear changes in place or idea. Whip pans: For energetic movement between related settings. Object wipes: Let a character, planet, cloud, or large shape pass across the frame and reveal the next shot. Color wipes: Fill the screen with a dominant color that becomes the next environment. Scale transitions: Zoom through an object into a new world. Shape morphs: Transform one illustrated object into another. Bright flashes: Reserve for exceptional reveals. Avoid random transitions. Every transition should serve the visual narrative. <TEXT AND TYPOGRAPHY> Keep typography clean, bold, and readable. Use fonts such as Montserrat, Poppins, or another suitable modern geometric sans-serif. Use text sparingly. Prefer visual explanations over full-screen paragraphs. Text may appear on: Signs Machines Labels Charts Screens Illustrated documents Purpose-built title compositions Animate text using: Scale pops Spring movement Staggered word entrances Slide-ins Shape reveals Keep titles visually distinct from ordinary labels. Avoid covering important characters with text. Do not add continuous burned-in subtitles unless requested. <TOOLS AND WORKFLOW> Use the following tools when available: Python for automation OpenCV for image and frame processing Pillow for sprites and alpha masks FFmpeg for rendering and encoding Playwright with Chromium for browser-based frame rendering NumPy and SciPy for calculations librosa for audio analysis faster-whisper for narration timestamps SVG or Canvas for animation Before production: Check the installed tools. Identify missing dependencies. Install missing packages if permitted. Report what was installed. Confirm the available rendering environment. If the environment cannot render the requested animation, do not pretend it can. Provide the executable project files and the remaining production steps instead. <RENDERING> Render the finished animation at: Resolution: 1920×1080 Frame rate: 60 FPS Codec: H.264 Encoder: libx264 Quality: CRF 16–18 Pixel format: yuv420p Use motion blur selectively for fast movement when supported. Before the final export, generate: Contact Sheet 1: Frames sampled across the beginning and middle of the video. Contact Sheet 2: Frames sampled across the middle and ending. Use at least 16 frames per sheet. Inspect both sheets. Fix: Inconsistent character designs Incorrect proportions Empty background areas Broken transparency Strange facial expressions Text overflow Missing props Unnatural camera crops Black frame borders Excessively static compositions Also inspect short preview clips, because contact sheets alone cannot reveal timing or motion problems. <SOUND DESIGN> Create a polished educational documentary mix. Use licensed or royalty-free music and effects. Music should feel curious, adventurous, and slightly cinematic. Match musical energy to the narrative. Suggested effects: Soft pops for appearing objects Whooshes for transitions Sparkles for discoveries Mechanical sounds for animated machines Soft impact sounds for landings Ambient sounds matching the environment Brief musical accents for surprising reveals Never overwhelm the narration. Use ducking or volume automation during spoken sections. Target an integrated loudness of approximately -14 LUFS when appropriate for the distribution platform. Avoid abrupt audio cuts. <QUALITY CONTROL> Before delivering the final video, verify: VISUALS Every scene uses the same illustration language. Character proportions and colors remain consistent. The environments feel detailed and intentional. There are no AI-generated visual artifacts. The video does not rely on static image zooms. ANIMATION Characters move naturally. Actions match narration. Movement uses appropriate easing. Transitions are visually coherent. There are no unexpected single-frame jumps. STORY The hook is clear. Every scene contributes to the explanation. The facts are accurate and sourced. The video delivers on its opening promise. AUDIO Narration is clear. Audio and visuals are synchronized. Effects are placed correctly. Music doesn't overpower speech. EXPORT The video plays correctly from beginning to end. No frames are missing. No assets appear blurred or distorted. The final MP4 has the intended resolution, frame rate, duration, and audio. Fix problems before delivering. <NON-NEGOTIABLE RULES> Do not use a generic AI slideshow approach. Do not use one flattened image for an entire animated scene. Do not randomly change character designs. Do not copy recognizable Kurzgesagt characters, logos, artwork, or exact compositions. Do not make every scene look identical. Do not use generic floating graphics when the idea could be illustrated inside the environment. Do not move objects without purpose. Do not ignore animation timing. Do not generate unreadable text inside images. Do not sacrifice factual accuracy for dramatic storytelling. Do not claim to have rendered or verified assets that have not been produced. Do not spend money or generate final assets without my approval. The goal is to create an original, vibrant, professionally animated educational film using the visual principles demonstrated by the attached reference. Prioritize visual storytelling, expressive character animation, coherent art direction, and polished motion.
