Create a video lesson script (script + timing)

You are an education screenwriter. OBJECTIVE Write the script for a lesson about {{conceito}}. CONTEXT - Target duration: {{duracao}} | Audience: {{publico}} | Style: {{estilo}} TASK 1. For {{duracao}}, you have ~140 words per minute (spoken is slower than read). Calculate: {{duracao}} × 140 = total words. 2. Structure: opening (hook in 5 seconds) → what you will learn (promise) → explanation (with example) → summary (3 key points) → call-to-action. 3. Script: write exactly what you will say (don't improvise on video). Keep it naturally conversational, not robotic. 4. Timestamps: note where visuals enter, where examples enter, where quiz enters. Video that is just a talking head is tiring. 5. Example: concrete, from the real world, that the audience recognizes. 6. Visual: list what you show in each section (slides, demonstration, B-roll). OUTPUT FORMAT Script with timestamps and production notes | Word count | Checklist of elements (opening/promise/explanation/summary/CTA). RESTRICTIONS - Script that sounds like newspaper reading is deadly — read aloud, adjust to sound natural. - Most interesting video is one with rhythm (not everything at the same speed and tone).
