Creating Educational Videos with AI

- Outcome
- One short lesson video
Always start with the script, never the tool
Every one of these tools turns text into video. The video is only as good as the script, so write it first in your assistant from Module 2, then paste it in.
Video script prompt
You are a [subject] teacher writing a narration script for a 3-minute explainer video for [level] students. Topic: [topic]. Structure: hook (15s) → one core idea → worked example → common mistake → 15s recap with a question for students. Rules: - Spoken language, short sentences, no bullet points inside the narration. - Around 380–420 words total (about 3 minutes at teaching pace). - After each paragraph, add [VISUAL: ...] describing what should appear on screen. - Do not invent statistics or references.
The [VISUAL] trick
The four tools and what each is for
Google Vids
Slide-style lesson video
- Free access
- Free tier with a Google account; fuller features via Workspace/Education
- Best for
- Structured lesson videos with narration, built like a deck
Vids feels like Slides with a timeline. You give it a topic or paste your script, it builds scenes with stock visuals, and you can narrate yourself or use a built-in AI voice. Easiest starting point if your school already uses Google.
- 1
Open Vids and choose 'Help me create'
Paste your script or a Docs link, and state the audience and length. - 2
Review the generated scene list
Delete scenes you do not need. One idea per scene. - 3
Replace weak stock visuals
Swap in your own diagram, screenshot or photo from Drive. - 4
Record or generate narration
Read the script yourself for warmth, or pick an AI voice for speed. - 5
Turn on captions and export
Share the link or download the MP4 for your LMS.
Google Flow
AI-generated video scenes
- Free access
- Free monthly credits with a Google account; limits apply
- Best for
- Short cinematic clips of things you cannot film: processes, history, abstractions
Flow generates video from a text description of a scene. Use it for the 5–10 second visuals that make a concept land — blood moving through a vessel, a volcano forming, a historical street scene — then drop those clips into your main video.
Prompt shape: subject + action + setting + camera + style. “A slow close-up of water droplets condensing on a cold glass, warm morning light, documentary style, no text.”
- Keep clips short and use them as illustration, not narration.
- Never use generated video as evidence of a real event — say on screen that it is an illustration.
- Generate two or three variations; credits are limited so keep prompts specific.
HeyGen
AI avatar presenter
- Free access
- Free tier: short videos per month with watermark
- Best for
- A consistent human presenter, multilingual versions of the same lesson
HeyGen puts a realistic presenter on screen reading your script. Ideal when you want a face and voice without recording yourself, or when you need the same lesson in English and Bahasa Malaysia.
- 1
Pick a stock avatar and voice
Match the register to your learners; test one paragraph before generating the whole video. - 2
Paste the script only
Remove your [VISUAL] notes — the avatar would read them aloud. - 3
Add pauses and emphasis
Short sentences and commas control pacing better than long clauses. - 4
Translate for a second version
Use its translate feature to produce a Bahasa Malaysia edition of the same video. - 5
Export and check pronunciation
Fix subject terms and names by respelling them phonetically in the script.
Disclose it. Add a line in the description: this presenter is an AI avatar; the content was written and checked by me.
InVideo AI
Script-to-video & AI editing
- Free access
- Free plan: limited AI minutes per week, exports watermarked
- Best for
- Fast complete videos from a prompt, plus captioning and voice-over editing
InVideo takes a topic or full script and assembles a finished video: stock footage, voice-over, background music and captions. Then you edit by instruction — “make scene 3 shorter, change the voice, add subtitles in Malay” — instead of dragging clips on a timeline.
- 1
Give it your script plus the audience
Specify length, tone, and 'educational explainer for [level] students'. - 2
Let it build the first cut
Expect roughly 70% usable. Do not fix details yet. - 3
Edit by instruction
Ask it to trim, swap footage, change voice, or rewrite one scene. - 4
Generate captions
Auto-subtitles, then read them once — subject terms are often misheard. - 5
Export
Free exports carry a watermark; that is usually fine for classroom use.

Captions, accessibility and quality control
- <strong>Always caption.</strong> Students watch on phones, in noisy rooms, and some need captions to follow at all.
- <strong>Read the captions once.</strong> AI transcription mangles subject terminology and local names.
- <strong>Check every on-screen number and label</strong> before sharing — generated visuals invent text happily.
- <strong>Keep it under four minutes.</strong> Two focused videos beat one long one for revision.
- <strong>State that AI was used</strong> in the video description, and that you verified the content.
Do not put student faces or names into these tools
Hands-on task
Build a short instructional video
Goal: A captioned video under three minutes on one concept your students find difficult.
