SHORT 04 • VIDEO INSTRUCTIONS & AI PROMPTS
CBSE Class 10 Science | Ch 1: Chemical Reactions and Equations | 9:16 • 1080×1920 • 48 sec
Production brief
Format: Faceless, premium vertical 9:16 YouTube Short, 48 seconds, 6 scenes. Voice: friendly Indian teacher in conversational Hinglish. Mood: exciting but scientifically precise. Palette: deep navy, cyan, white and yellow; keep formulas large and legible.
Safe-frame: keep essential text away from the lower 25% and right 15% where interface overlays may appear. Do not show children handling burning magnesium. Do not encourage any home experiments.
Global AI video prompt
Create photorealistic virtual chemistry demonstration footage blended with elegant 2D motion graphics. Use a controlled magnesium ribbon combustion experiment: extremely bright white light, white magnesium oxide product. Correct balanced equation 2Mg + O₂ → 2MgO. Never depict magnesium oxide as smoke of a different colour. For any molecular animation, use abstract atom counters rather than invented chemical reaction mechanisms. Produce separate vertical clips according to the following shot list, no background narration embedded in generated visuals; add all text and formulae as verified editing overlays.
Timed scene storyboard and individual generation prompts
Scene 01 | 00:00–00:04 | Hook
Visual / AI scene prompt: Cinematic macro of a silver-grey magnesium ribbon held with tongs inside a controlled virtual school laboratory. Abrupt transition to an intensely bright white combustion glow, expose highlights carefully for readability. On-screen: “WHY SO BRIGHT?” Do not show a student performing this.
Narration cue (reference only): Kabhi magnesium ribbon ko jalte dekha hai? Itni dazzling white light kyun?
Scene 02 | 00:04–00:11 | Observation
Visual / AI scene prompt: Wide view: science instructor wearing eye protection handles magnesium with tongs behind a safety screen; virtual controlled flame. Show air/oxygen nearby; avoid fictitious green or blue fire. On-screen: “Magnesium + Oxygen”.
Narration cue (reference only): Teacher-supervised experiment mein magnesium oxygen ke saath react karta hai.
Scene 03 | 00:11–00:20 | New substance
Visual / AI scene prompt: Match cut: intense white glow fades to white MgO powder in a heat-resistant dish. Label Mg (magnesium ribbon) → MgO (white solid). Show two distinct substances visually. No literal molecular pathway claims.
Narration cue (reference only): Reaction ke baad banta hai ek naya substance — white magnesium oxide powder.
Scene 04 | 00:20–00:32 | Equation
Visual / AI scene prompt: Clean vector equation appears one component at a time: 2Mg + O₂ → 2MgO. Animate counting Mg:2→2 and O:2→2 using abstract counters only. Typeset equation as overlay, not AI generated lettering.
Narration cue (reference only): Balanced equation hai: two M G plus O two gives two M G O. Dono sides par magnesium aur oxygen atoms equal hain.
Scene 05 | 00:32–00:40 | Why bright?
Visual / AI scene prompt: Scientific virtual flame clip with glow carefully not overblown; animated outward arrows labelled “Heat” and “White Light”. On-screen: “Combination + Exothermic Reaction”.
Narration cue (reference only): Ye reaction energy heat aur bright white light ke form mein release karta hai.
Scene 06 | 00:40–00:48 | Recap + CTA
Visual / AI scene prompt: Fast recap cards: “MgO = White solid”; “2Mg + O₂ → 2MgO”; shield icon “Teacher-supervised only”. Finish with “Class 10 Science • Next Short →”. Never invite home experimentation.
Narration cue (reference only): Exam tip: Magnesium oxide white hota hai! Aur yaad rakho, burning magnesium ko directly mat dekho. Next science short dekho!
Exact overlay text and equation
• WHY SO BRIGHT?
• Magnesium + Oxygen
• MgO = White Solid
• 2Mg + O₂ → 2MgO
• Mg atoms: 2 = 2 | O atoms: 2 = 2
• HEAT + BRIGHT WHITE LIGHT
• Combination + Exothermic
• Safety: supervised laboratory only
Edit, audio and QA
• 0–3 seconds: impactful hook; quick cuts but never sacrifice readability.
• Voiceover should lead each visual, using exact matching timestamps in the companion document. Add concise English subtitles with word-level highlights.
• Sound: subtle cinematic whoosh at 0:01, short controlled ignition effect at 0:05, gentle musical pulse throughout at least 18 dB below narration. Do not simulate explosive sounds.
• At scene 04, pause briefly after showing the equation for viewers to count atoms.
• Science check: 2Mg + O₂ → 2MgO; white MgO product; energy as heat and bright white light; magnesium and oxygen conserved.
• Safety check: do not stare directly at burning magnesium; teacher supervision and suitable laboratory precautions required.
• Export: MP4 H.264, 1080×1920, 30 fps, AAC audio, captions burned in.
