Create a polished educational explainer video based on the single teaching point provided below.
## User Input
**Teaching point:**
{{Supply and Demand}}
## Main Task
Automatically analyze the teaching point and determine:
* the most relevant subject
* the appropriate learner level
* the essential definitions and background knowledge
* the clearest teaching sequence
* the most suitable visual explanations
* one practical worked example
* common mistakes or misunderstandings
* one short practice question
Do not require the user to provide a script, outline, examples, narration, visual style, or scene directions.
Create one complete educational explainer video divided into exactly **6 sequential scenes**.
The six scenes should feel like six animated pages of the same visual learning book.
Each scene must have:
* one clear learning purpose
* one major visual focus
* concise on-screen text
* synchronized narration
* smooth educational animation
* a natural transition into the next scene
Do not show all six scenes together as a collage, grid, split screen, or page overview.
## Video Structure
### Scene 1: Title and Learning Goal
Introduce the topic with a strong visual opening.
Include:
* a clear lesson title
* a short subtitle
* one sentence explaining what the learner will understand
* one central animated visual related to the topic
The opening should immediately communicate the subject and purpose of the lesson.
Example narration structure:
“Today, we are learning about {{teaching point}}. By the end of this lesson, you will understand how it works and how to use it.”
Keep the introduction brief and engaging.
### Scene 2: Concept Introduction
Explain the basic meaning of the concept.
Include:
* a simple definition
* why the concept matters
* essential vocabulary
* one visual analogy or real-world example
Animate the information gradually rather than displaying everything at once.
For example:
* labels appear beside relevant objects
* key words highlight as they are spoken
* arrows reveal relationships
* visual components assemble step by step
Avoid introducing too much technical information at once.
### Scene 3: Core Explanation
Explain the central rule, process, principle, formula, or structure.
Break the concept into small, logical steps.
Use the visual format that best fits the topic:
* animated diagram
* number line
* equation breakdown
* sentence structure
* cause-and-effect flow
* scientific process
* timeline
* comparison
* labeled model
* step-by-step transformation
Reveal each component only when it is mentioned in the narration.
When using a formula:
* introduce each symbol separately
* explain what each variable means
* show the relationship visually
* include correct units where necessary
Do not present unexplained formulas or terminology.
### Scene 4: Worked Example
Show one clear example from beginning to end.
Start with a realistic problem, sentence, question, or situation.
Then demonstrate the solution step by step.
For mathematics or physics:
* display the problem
* identify the known information
* select the correct formula or method
* substitute the values
* show each calculation
* highlight the final answer with the correct unit
For grammar or language:
* show a sentence or language example
* identify the relevant rule
* highlight the important words
* revise or analyze the sentence step by step
* reveal the correct final version
For science:
* show a process, experiment, natural event, or cause-and-effect example
* animate each stage in the correct order
* connect the visual evidence to the main concept
For history or social studies:
* show a specific event, decision, comparison, or historical sequence
* clearly distinguish causes, actions, and outcomes
The example must be accurate and understandable without outside explanation.
### Scene 5: Common Mistakes and Helpful Tips
Show two or three common misunderstandings.
Use a clear visual comparison such as:
* incorrect versus correct
* misconception versus fact
* weak example versus improved example
* wrong method versus correct method
Briefly explain:
* what the mistake is
* why it happens
* how to correct it
* one memorable tip
Use supportive language.
Do not shame the learner or make mistakes feel frightening.
Use visual signals carefully:
* a subtle red indicator for incorrect information
* a green check for correct information
* highlighting or arrows to show what changed
### Scene 6: Summary and Mini Practice
Conclude the lesson with:
* three concise key takeaways
* one short practice question
* a brief pause for the learner to think
* the correct answer and a simple explanation
Show the practice question first without immediately revealing the answer.
Use a visible countdown, thinking animation, or short pause.
Then reveal the answer step by step.
End with a confident closing line such as:
“Now you know how {{teaching point}} works and how to apply it.”
The final frame should show the lesson title and one memorable takeaway.
## Automatic Subject Adaptation
Adapt the explanation, visuals, pacing, and animation to the detected subject.
### Mathematics
Use:
* equations
* number lines
* graphs
* shapes
* geometric models
* visual quantities
* color-coded calculation steps
* aligned mathematical notation
Animate calculations one step at a time.
Ensure all values, operations, symbols, and answers are mathematically correct.
Do not skip important calculation steps.
### English Grammar and Language Learning
Use:
* sentence cards
* highlighted words
* animated punctuation
* grammar labels
* word transformations
* speech bubbles
* incorrect-and-correct sentence comparisons
Keep example sentences natural and age appropriate.
Check all spelling, grammar, punctuation, and word usage carefully.
### Physics
Use:
* real-world objects
* force arrows
* motion paths
* vectors
* graphs
* labeled variables
* formula breakdowns
* correct scientific units
Motion and forces must behave realistically.
Arrows must point in scientifically accurate directions.
### Biology and Chemistry
Use:
* labeled scientific illustrations
* process animations
* molecule or cell diagrams
* magnified details
* stage-by-stage transformations
* cause-and-effect arrows
Keep anatomy, chemical structures, biological processes, and scientific relationships accurate.
Avoid visually dramatic effects that distort the science.
### History and Social Studies
Use:
* animated maps
* timelines
* historical objects
* location markers
* cause-and-effect chains
* comparison cards
* chronological transitions
Do not invent people, dates, quotations, locations, or historical events.
Clearly distinguish established facts from interpretations.
### Writing and Study Skills
Use:
* annotated examples
* paragraph structures
* planning diagrams
* checklists
* before-and-after revisions
* color-coded writing components
Show how the skill can be applied, not just described.
## Visual Style
Use a modern animated visual-book style suitable for students and young adults.
The overall video should feel:
* intelligent
* clear
* contemporary
* inviting
* educational
* visually organized
* professional without feeling rigid
Use:
* one major visual focus per scene
* clean backgrounds
* spacious layouts
* rounded educational cards
* subtle depth and shadows
* smooth icon and diagram animation
* consistent typography
* a coordinated color palette
* strong text-to-background contrast
Maintain the same:
* illustration style
* color system
* typography
* transition language
* icon design
* character design
* animation quality
across all six scenes.
Avoid overly childish classroom graphics unless the topic clearly targets young children.
Avoid excessive decoration, random stickers, visual clutter, or unrelated animations.
## Narration Rules
Generate a complete voice-over script automatically.
The narration should:
* sound natural and knowledgeable
* use clear, conversational language
* explain each visual as it appears
* avoid unnecessary repetition
* define unfamiliar vocabulary
* use age-appropriate wording
* maintain a calm educational pace
Keep each spoken sentence concise.
Do not make the narration sound robotic, overly enthusiastic, or like an advertisement.
Use one consistent narrator voice throughout the video.
The narrator’s spoken explanation must match the visuals and on-screen text exactly.
## On-Screen Text Rules
Keep on-screen text brief and readable.
Use text mainly for:
* titles
* definitions
* keywords
* formulas
* labels
* example steps
* takeaways
* the practice question
Do not place the full narration on screen as subtitles unless subtitles are specifically enabled.
Do not use:
* long paragraphs
* tiny text
* unreadable formulas
* excessive labels
* decorative text that adds no educational value
Display no more than one main heading and a small amount of supporting text at the same time.
All visible text must be correctly spelled and grammatically accurate.
## Animation Rules
Use purposeful animation that helps explain the concept.
Suitable animations include:
* objects appearing in sequence
* arrows tracing movement or relationships
* words highlighting as they are discussed
* formulas assembling step by step
* diagrams building from simple to complex
* numbers moving into equations
* sentence components shifting into the correct order
* maps zooming toward relevant locations
* process stages transforming smoothly
Do not use random movement merely to keep the screen active.
Avoid:
* rapid camera movement
* excessive zooming
* distracting transitions
* shaky elements
* flashing text
* chaotic particle effects
* objects changing shape unintentionally
* diagrams appearing before they are explained
All animation should support comprehension.
## Accuracy and Logic Rules
Educational accuracy is the highest priority.
Before generating the video:
* verify the definition
* check all facts
* check mathematical calculations
* check formulas, symbols, and units
* check spelling and grammar
* ensure diagrams match the narration
* ensure the example has a valid solution
* ensure the practice question tests the lesson directly
* ensure the revealed answer is correct
When the topic has multiple meanings, choose the most widely taught introductory interpretation and clearly define it.
Do not fabricate information to complete a scene.
Do not introduce advanced concepts that have not been explained.
## Timing and Transitions
Give each scene enough time for the learner to understand the information.
Suggested pacing:
* Scene 1: brief introduction
* Scene 2: basic concept
* Scene 3: detailed explanation
* Scene 4: worked example
* Scene 5: mistakes and tips
* Scene 6: recap and practice
Use smooth page-turn, card-slide, diagram-build, or gentle camera transitions.
Transitions should connect related ideas rather than interrupt the lesson.
Do not cut to the next scene before the narration and visual explanation are complete.
## Output Requirements
Generate one complete educational explainer video with exactly **6 sequential scenes**.
Treat each scene as one animated page of a visual learning book.
The final output must include:
* six clearly structured scenes
* synchronized narration
* concise on-screen text
* subject-appropriate educational visuals
* smooth transitions
* one worked example
* common mistakes
* one practice question and answer
The final video must feel like one coherent lesson that moves naturally from introduction to explanation, application, correction, and practice.
