Slides to lecture videos
Turn your slides into a course of lectures
Lecture Video Maker turns a teacher's slide deck and lecture notes into a whole course of lecture videos, one MP4 per lesson with each slide on screen, the narration, and subtitles, plus an SRT file beside every video. The narration can use a clone of the teacher's own voice, made once for the whole course, and a digital-human teacher made from one photo can open and close each lesson. Lecture Video Maker works in Claude Code, Codex, Cursor, and other agents that run Skills.

A finished video for every lecture
Your slides on screen
Each slide stays on screen while the voice explains it, just as you teach it.
The teacher's own voice
Clone your voice once for every lesson, or pick a narrator that suits the subject.
A whole course in order
One subtitled video per knowledge point, made lesson by lesson in teaching order.
How it is made
Every slide gets a script the teacher approves
Speaker notes become the script; a slide without notes gets one written from what it shows, in the teacher's register.
Use speaker notes as the script · Choose rigorous, warm, or concise · Settle readings of names and terms
Your own voice, and a digital teacher when you want one
Clone the teacher's voice once, add a corner photo, or let a digital-human teacher open each lesson or chapter.
Clone the teacher's voice once · Add a corner photo · Open lessons with a digital teacher
One lecture video per knowledge point
Watch a short pilot first, then the course is made lesson by lesson in teaching order, each video with its subtitles.
Start with a three-minute pilot · One video per knowledge point · Subtitles on every video
