Course videos without re-recording: turn decks into sellable lessons
Re-recording is the most expensive part of selling a course. Import the deck, let AI write and voice the lesson, align captions and motion, render locally — and when the content changes, only the changed pages are redone.
Three traps every course seller knows
One update means a full re-record
Product changes, expired examples, new regulations: record again, edit again, upload again. By the third version you don't want to touch the course.
Production costs more than the content
A 20-lesson course is typically three to six weeks of filming and editing, quoted per finished minute, with every revision billed again.
No camera presence, so it reads like a script
Tension, filler words, endless retakes — the course you finally publish is one you wouldn't watch yourself.
From deck to sellable course in three steps
- 1
Turn the deck into the curriculum
One deck per lesson, split by concept: twenty lessons become twenty projects, and the deck structure becomes the course structure.
- 2
AI drafts, you supply the judgement
AI writes per-page narration; you fix the professional judgement and the examples, then generate the voice. Mistakes cost nothing.

All publishing assets in one pass
Captions, chapter timestamps, cover, title, description and tags export with the video, ready for the course platform.
What course sellers actually care about
Edit one page, redo one page
Update the deck and only the changed pages get new narration and captions; everything else stays exactly as rendered.
Four narration modes
Solo for teaching, two-host for interviews, teacher–student for Q&A lessons, news anchor for updates — different texture per course type.
Course-grade finish
Five caption styles, six scene animations and Ken Burns motion make the lesson look like a course rather than a screen recording.
Chapter timestamps, generated
Long lessons are chaptered so students can jump to the part they need — completion rates follow.
Rendered on your machine
Video renders on your own Mac, and decks and films stay in the app sandbox instead of a stranger's server.

What course creators ask first
Do I have to re-record when the course changes?
No. Re-import the new deck, regenerate voice and captions only for the changed pages, render again. Untouched pages keep their narration, captions and timing — no re-alignment.
How long does a 20-lesson course take?
About 20–30 minutes per 10–15-page lesson for script, voice and render, so twenty lessons fit into two or three focused days. The saved time belongs to content and marketing, not audio editing.
Can I publish to course platforms?
Yes. Export standard MP4 (up to 4K) with a sidecar .srt, cover, title, description and tags — usable on any platform that accepts video uploads. For a preview clip, use split export on the first two lessons.
Can the whole course look consistent?
Yes. Fix the voice, caption style, intro and animation style across lessons; the platform templates keep framing and caption position identical, so lessons don't look stitched together.
What does it cost?
About 352 credits per 10-page lesson (≈$0.58); import, editing, voice previews, rendering and export are free, and 600 welcome credits get you started. A 20-lesson course of 10-page lessons works out to roughly $11.55 of AI cost — see [pricing](/pricing).
