<task> Create a complete, highly professional video featuring this style of animation about the subject:Why Does Your Shadow Change Length During the Day? from A to Z. </task> <format_and_output> * Video Ratio: Vertical format (9:16 aspect ratio for TikTok/Reels/Shorts). * Script Language: Output the voiceover script in English. </format_and_output> <content_and_script> * Subject Detection & Hooking: Automatically detect the subject type across any niche, domain, or topic (e.g., historical story, scientific concept, mystery, human biology, life hack, psychology, mythology, or any other subject). Choose the optimal narrative format, visual structure, and pacing to strongly hook the audience—flexibly utilizing techniques like an opening pattern interrupt, high-stakes framing, or curiosity gaps depending on what best suits the topic. * Content Trimming: You have full authority to ignore or omit any details, technical fluff, or background facts that are unnecessary or could negatively impact pacing, clarity, or viewer retention. Keep only what drives maximum engagement. * Accuracy & Tone: Base the content strictly on accurate, verified facts. * Engagement & Flow: Avoid boring, slow, or overly complex explanations. Keep viewer curiosity high by revealing insights dynamically without stalling the story momentum. * Script Clarity: Explain the concept so a 10-year-old can understand it instantly (no jargon without simple definitions). * Sentence Structure: Short, punchy sentences (maximum 10 to 12 words per sentence). * Seamless Loop: Formulate the final voiceover sentence to naturally and fluidly connect back into the opening hook line for an uninterrupted infinite loop. </content_and_script> <visual_style> * Style: Modern, high-end 2D pixel illustration style with rich multi-tone shading, expressive silhouettes, dynamic lighting, and spatial depth (e.g., isometric pixel perspective, room cross-sections, and detailed layered backgrounds). * Negative Filter: Strictly avoid primitive, unshaded single-color boxes or flat MS-Paint style blocks. Characters, anatomical figures, historical assets, and objects must look professionally detailed with depth, clear outlines, and polished visual appeal. * Visual Metaphors & Progression: Use clear visual metaphors (e.g., toggles, meters, icons, animated state changes, scale shifts) as visual micro-rewards to keep concepts simple and visually engaging. * Palette: Choose any visual color palette or mood that best fits the subject while maintaining high contrast and readability on mobile screens. </visual_style> <audio_and_pacing> * Subtitles: Subtitles are crucial (display a maximum of 1 to 3 words on screen at a time in the bottom center). * Music: Do NOT add any background music (I will add it myself). * Sound Effects: Increase the volume of the sound effects (SFX) (amplified retro pixel clicks, pops, whooshes, and impact booms). * Duration: Must be between [ 50 - 90 ] seconds (choose the optimal length within this range). * Quality & Pacing: Professional-level animation with a strong hook in the first few seconds. Maintain active visual progression naturally adapted to the rhythm of the story, ensuring no single visual frame remains completely static. </audio_and_pacing> <deliverables> 1. The final video file. 2. The voiceover script (as a text file) so I can generate the audio separately. </deliverables> use internet tousd study how you will give the video so peaple love it and watch it, +hook is so importante, and improuve animation, detaille, quality, make no mistakes, I want a video profeionele that only studios can make, so that mene taht the animation doit etre riches, a lote of sound effect, a lote of scenes, without scene repitition, use internet to take all information you want, and dowload all ressources you want, and do watever you want, so you can use browser use to exceed your limite, I do NOT want a low-resolution final video or a production strategy that sacrifices the final visual quality to save rendering time. * Duration update: The final video must be between 35 and 60 seconds. This replaces the earlier 50-to-90-second duration range. Choose the best duration within 35 to 60 seconds for the subject and story. Keep the narration concise enough to sound natural and unhurried. * Before production, research the subject using reliable, relevant sources. Verify every factual claim that appears in the narration or visuals. Prefer authoritative sources such as scientific institutions, museums, universities, peer-reviewed publications, and reputable reference organizations. Do not invent facts, statistics, quotes, or sources. * Also study relevant professional examples and references for visual storytelling, animation, pacing, and mobile-first short-form videos. Use them for general inspiration only. Do not copy another creator’s script, distinctive style, characters, or assets. * Use original, generated, or properly licensed production assets. Do not use copyrighted material unless its use is clearly permitted. Keep a concise source and asset note for any external factual reference or asset used. * Design the video for immediate comprehension and strong viewer interest. Make the opening image and first spoken line instantly understandable and intriguing. Build curiosity with a clear question, surprising contrast, visual reveal, or other hook that genuinely fits the subject. Do not use misleading clickbait. * Give every scene a clear purpose. Make the story progress visually from scene to scene, with varied compositions, camera movement, scale, character action, lighting, and visual metaphors. Avoid repeated scenes, recycled shots, unnecessary transitions, and static frames. Use polished animation timing, appealing motion, expressive poses, depth, layered environments, and deliberate visual transitions. * Make the visuals easy to understand even when viewed on a small phone screen. Keep the main subject prominent, use strong contrast, and avoid clutter. Each important visual should reinforce the spoken idea rather than distract from it. * Write the narration in simple, natural, conversational English that a 10-year-old can understand immediately. Use vivid but familiar words, short sentences, and clear explanations. Preserve the original maximum of 10 to 12 words per spoken sentence. Remove jargon, filler, repeated ideas, and unnecessary setup. * Make the on-screen subtitles highly readable, accurately synchronized, and easy to grasp at a glance. Preserve the original limit of 1 to 3 words displayed at a time. Break the narration into meaningful subtitle chunks, emphasizing the most important words without obscuring faces or key visuals. Check spelling, timing, contrast, and safe placement for vertical mobile viewing. * Create an exceptionally detailed, performance-ready voiceover script as a separate text file. Include the exact narration verbatim, divided by scene and aligned to approximate timestamps. Do not include performance directions in the spoken lines. * For each scene or spoken line, add clear voice-performance directions for the narrator: intended emotion, energy, vocal tone, pace, emphasis on specific words, pauses, breaths, sentence endings, and transitions into the next line. Include pronunciation guidance for unusual names or technical words. Keep these directions specific and actionable, not vague. * Define an overall voice profile for the complete narration, including the desired age impression, vocal character, warmth, clarity, energy, conversational style, and consistency. The voice should sound confident, friendly, expressive, and natural—not robotic, exaggerated, rushed, or monotonous. * Pace the voice so every word is easy to hear and understand. Leave enough space for important reveals and visual moments. Keep narration intelligible above sound effects at all times. Sound effects may be vivid and impactful, but must never mask words or cause unpleasant volume spikes. Do not add background music. * Before delivery, review the complete video and voiceover together. Check that the duration is within 35 to 60 seconds, every visual matches the narration, the subtitles are synchronized and readable, the facts are accurate, the narration is natural and easy to follow, and the audio is clean. Fix any errors before exporting. * Deliver the final video and the detailed, performance-ready voiceover script. Include a concise source and asset note separately, not as part of the spoken narration. USE INTEERNET TO GET ALL ANALYSES AND IMFORMATION YOU WANT
