This is the exact pipeline for turning your Zoom classroom into a polished AI lecture MOOC.
PHASE 1 — Extract Teaching Structure (AI Automated)
Step 1. Extract Transcript
Tools:
•
Zoom transcript

Step 3. Convert to Script
Your AI will:
•
rewrite teacher speech → MOOC-friendly narration
•
clean filler words
•
tighten explanations
•
add examples where needed
•
structure into a script with cues
Outputs:
•
Clean explainer script

This step is 100% AI-automated once the prompt template is perfected.
PHASE 2 — Generate Visuals (AI Automated)
Step 4. Generate Presenter Avatar
Tools:

These replace your actual Zoom classroom visuals with something more MOOC-like.
PHASE 3 — Generate Voice (AI Automated)
Step 6. Generate Voiceover
Tools:
•
ElevenLabs voice clone

Or choose prebuilt academic voice
Input:
•
Clean script from Phase 1
Output:
•

Optional: teacher’s own cloned voice (if permitted)
PHASE 4 — Assemble the Video (Partially Manual)
Step 7. Timeline Assembly
Tools:
•
Veed.io
•
