How to edit course and lesson videos with AI

What makes a lesson video easy to follow?

People watching a lesson need orientation. They want to know the topic, which step they're on and the one thing to remember. A captioned talking head alone can leave them lost, while on-screen structure gives them anchors.

• A short title that says what the video teaches.
• A card at the start of each part.
• One key point shown when you make it.
• Captions so the lesson works in a noisy room or without sound.

What does Explainer add to your clip?

Explainer keeps you large and sharp over a softened copy of your own shot, and puts a title line and one simple visual above your head. Header cards open each part, and short points appear as you say them, so viewers know where they are.

Captions sit on a dark pill under your chin and follow your voice word by word, with the key word in gold. It makes vertical 9:16 video.

What is a sensible workflow for a course?

1. Plan each lesson as one idea in a short clip, so each header card and key point has a clear job.
2. Film to camera with even light and clear audio.
3. Run each clip through Explainer and review the stills.
4. Fix any caption words, especially jargon and names.
5. Render, then add any intro or outro in your editor.

Explainer outputs vertical 9:16. If your course platform needs widescreen video, Layers supports 16:9; see its page.

What does it not do?

• It does not write your lesson or check your facts.
• It does not add screen recordings or slides. Combine it with your screen-recording tool if you need those.
• It is not a long-form course editor. Test it on a short lesson first.
