To make online course videos with AI, start with the outcome a student should reach, break it into modules and 3 to 8-minute lessons, choose a recording style per lesson (screen, slides or camera), script or outline each lesson with an AI assistant, record in short segments, and let an AI editor remove silences and filler words, add captions and zooms, and export at 1080p. Then check the platform's rules: Udemy requires every video to be at least 720p and under 4 GB, with at least 30 minutes of video across at least 5 lectures, and Skillshare requires a class of at least 10 minutes with a project. Finally, cut 30 to 60-second clips from the lessons to market the course on Shorts, Reels, TikTok and LinkedIn.
This guide is for experts, educators, coaches and companies building a paid or free course. It covers planning, lesson length, recording styles, scripting, equipment, AI editing, narration options including faceless lessons, platform requirements, accessibility, marketing clips, updating and common mistakes. Facts are current as of October 2026.

Step 1: Plan the Course Around Outcomes, Not Topics
Courses that get finished are built backwards from what the student can do at the end. Write that sentence first (“By the end, you can build and publish a Shopify store that takes payments”), then list the five to eight capabilities it requires, which become modules, then the steps inside each capability, which become lessons. Every lesson title should be a verb phrase describing what the student does in it, and every lesson should end with the student having done it.
AI is useful here as a critic rather than an author. Paste your outline into ChatGPT or Claude and ask what a beginner would be confused by, which lessons depend on knowledge you haven't taught yet, and where a lesson tries to do two things. The free YouTube outline generator and YouTube content planner give you a structure to react to if the page is blank.
How Long Should Course Videos Be?
Three to eight minutes per lesson, with the occasional 10 to 12-minute lesson for a complex task. Short lessons are finished more often, are easier to update when one step changes, and show students progress in a sidebar. A 30-lesson course at 5 minutes each is two and a half hours, which is substantial on any platform.
Platform minimums matter at the low end. Udemy requires at least 30 minutes of video content and at least 5 separate lectures to publish, and each video must be at least 720p and under 4 GB; free Udemy courses published since March 2020 must be under two hours (Udemy Support). Skillshare requires a class of at least 10 minutes; its short-form classes run 2 to 15 minutes, standard classes usually run 20 to 60 minutes split into short lessons, and classes over 15 minutes need an intro, an outro and a class project students can post (Skillshare Help). Teachable, Thinkific, Kajabi and your own site set no minimums.
The free video length calculator converts a script's word count into runtime: at a teaching pace of about 130 words per minute, a 5-minute lesson is roughly 650 words.
Step 2: Choose a Recording Style for Each Lesson
Screen recording: for software, spreadsheets, code and any task done on a computer. The student sees exactly what to click. Record at 1920×1080 with the interface enlarged, and add a small webcam overlay in the intro if you want a face. Our tutorial video guide covers demo setup and free recorders.
Slides with narration: for concepts, frameworks and theory. Keep fewer than 15 words per slide and add a build or a diagram every 20 to 30 seconds; our PowerPoint to video guide has the export paths.
Camera: for introductions, motivation, demonstrations of physical skills and anything where trust matters. Talking-head lessons work best as the first video of each module and for the course welcome.
Faceless narrated video: for courses where the instructor doesn't appear or for concept lessons produced at volume. Narration over illustrative visuals with captions, built from a script in a tool such as Vidpal Studio. More on this below.
Most courses mix them: a camera welcome, slides for concepts, screen recordings for tasks, and a camera wrap-up. Consistency within a type (same layout, same caption style, same intro card) matters more than using one type everywhere.
Step 3: Script or Outline Each Lesson With AI
Task lessons (screen recordings) work from a bullet outline: the steps as verb phrases, the exact names of buttons and settings, the common error, and the result. Concept lessons work from a full script, because precision and pacing matter and captions need to be exact. Both should open by showing or stating the result of the lesson in the first 15 seconds, and both should close by telling the student what to do before the next lesson.
A prompt that works: “Write a 5-minute lesson script (about 650 words) for a beginner on [task]. Open by showing the finished result, list the prerequisites in one sentence, walk through the steps in order with the exact UI labels, explain the one mistake beginners make, and end with a one-line practice task. Short sentences, spoken language, no jokes.” Then correct the UI labels against the real software and read it aloud. The video script generator drafts a version from an outline if you prefer, and our guide to ChatGPT prompts for video scripts has more sequences.
Keep a glossary of your terms and a short style note (how you address the student, the words you avoid) and paste it into every prompt so the course sounds like one person.
Step 4: Equipment and Recording Setup
Audio decides whether a course feels professional. Use a USB microphone 10 to 20 centimeters from your mouth, in a room with soft furnishings, with fans and notifications off; a dynamic microphone forgives an untreated room. For camera lessons, a phone on a stand at eye level facing a window, a plain background and a lapel microphone are enough. For screen lessons, enlarge the pointer and the interface to 125 to 150 percent and use test data, never real customer records. Run the free screen recording checker if you record in a browser-based tool.
Record in short segments and repeat any sentence you fumble. Keep a second of silence before each restart. Don't stop to edit; AI handles the gaps, and short takes are easy to re-record when the software updates. Rehearse each task once before recording so the demo doesn't wander.
Step 5: Edit the Lessons With AI
Upload each recording to an AI editor and apply the same settings to every lesson. In Vidpal's AI Editing, the file is transcribed, silences and filler words are removed, captions are added from one of 75 presets, auto zooms emphasize moments, and auto b-roll covers talking-head stretches. For courses, keep zooms modest and never let b-roll cover a screen while a step is happening; keep a short pause after each click so students see the result. The guides to removing silences and filler words and adding sound effects and transitions cover the settings.
Export 16:9 at 1080p, which satisfies Udemy's 720p minimum with margin and looks sharp on a laptop. Name files by module and lesson number so uploads stay in order. Keep the project files: when a lesson needs updating, you re-record one segment and re-export rather than starting over.
Use the transcript the editor produced as the lesson's text version. Students search course text, platforms index it, and it becomes a downloadable resource with almost no extra work.
Faceless Course Lessons With AI Narration
Concept lessons don't need a face or a screen. Write the script, build the lesson in Vidpal Studio with a voice, stock footage or AI images in 20 styles matched to each scene, and captions; a 16:9 video of 1 to 10 minutes costs 5 credits. This suits courses produced at volume, courses in a voice other than the instructor's, and instructors who won't go on camera. Keep the visual style consistent across the course by using the same image style and caption preset, and open each lesson with the same short title card. Mix in a real camera welcome per module so students know who is teaching; see our guides to making faceless videos with AI and making educational Shorts for the production approach.
Two cautions. First, check the platform: some marketplaces have rules about AI-generated narration and most expect you to disclose it in the course description, so read the current quality guidelines before you build thirty lessons that way. Second, AI narration mispronounces technical terms and reads numbers oddly, so listen to every lesson before publishing and spell out tricky terms phonetically in the script. Our AI voiceover tools roundup compares the voices.
Platform Requirements: Udemy, Skillshare, Your Own Site
Udemy: each video at least 720p and under 4 GB; at least 30 minutes of video and 5 lectures; audio on both channels and in sync; no distracting background noise; Udemy recommends submitting a test video for feedback before recording the full course (Udemy Video Standards). Courses are reviewed before publishing.
Skillshare: at least 10 minutes of video; a class project; short-form classes of 2 to 15 minutes without a formal intro, or standard classes of 20 to 60 minutes with an intro, an outro and several lessons (Skillshare Class Quality Guidelines).
Teachable, Thinkific, Kajabi and self-hosted: no minimums, your pricing, and you own the student list. Hosting costs scale with video; the video hosting cost calculator estimates them, and the video compressor shrinks large exports.
YouTube: a free course as a playlist, or an unlisted playlist as a lead magnet. Chapters and clear titles matter more than on course platforms; our guide to making a long-form YouTube video with AI covers packaging.
Accessibility: Captions, Transcripts and Readability
Captions are not optional for a paid course. Students with hearing impairments, students watching in a second language and students on a train all need them, and accessibility standards such as WCAG require captions for prerecorded video. Upload an SRT or VTT file to the platform (AI editors export one, and the subtitle SRT generator creates one from a transcript) and provide the transcript as text. Check the captions for technical terms, because speech recognition mangles them. Enlarged interfaces, high-contrast caption presets and a pace of about 130 words per minute help everyone.
Step 6: Market the Course With Clips From the Lessons
The lessons are the marketing. Take the three most surprising or useful 30 to 60-second moments, cut them as 9:16 clips with captions, and post them to Shorts, Reels, TikTok and LinkedIn with the course link in the profile or the description. Vidpal's AI Clips extracts scored segments from a long upload automatically, covered in our podcast to clips guide and LinkedIn video guide.
Make a 60 to 90-second trailer that states the outcome, shows three moments from the lessons and names who the course is for; Udemy and Skillshare both display a promo video. Then publish one educational Short a week from the course material on a schedule; our guide to educational Shorts covers the format, and the scheduler page covers posting to several platforms at once.
Updating a Course Without Re-Recording It
Software changes and courses rot. Three habits keep updates cheap: record in short segments so one step can be replaced; keep slides and scripts in editable files so a changed number is a text edit; and prefer narrated or faceless lessons for the content most likely to change, since re-rendering a script is faster than re-filming a face. Review the course quarterly, re-record the lessons students report as outdated, and add a dated “what changed” lesson at the top.
Common Mistakes in Course Video Production
Teaching topics instead of outcomes: students buy a result. Build backwards from it.
Long lessons: a 25-minute lesson is five lessons. Split it.
Perfect production, weak audio: a clear voice on a plain screen beats a cinematic intro with echo.
No captions or transcript: it excludes students and fails accessibility requirements.
Recording before rehearsing: the demo wanders and the edit takes twice as long.
Ignoring platform minimums: a 25-minute course can't publish on Udemy.
Building the whole course before testing one module: publish a module or a free mini-course first, read the questions, then build the rest.
Key Takeaways
Takeaway one: plan from the student's end result to modules to 3 to 8-minute lessons titled as actions.
Takeaway two: choose screen, slides, camera or faceless narration per lesson, and keep the layout and caption style consistent.
Takeaway three: script concept lessons, outline task lessons, record in short segments with a good microphone, and let AI editing cut silences and add captions.
Takeaway four: Udemy requires 720p, under 4 GB per video, 30 minutes and 5 lectures; Skillshare requires 10 minutes and a project; self-hosted platforms set no minimums.
Takeaway five: captions and transcripts are required for accessibility, and clips cut from the lessons are the cheapest marketing you have.
Frequently Asked Questions
How long should online course videos be? Three to eight minutes per lesson, with a few longer lessons for complex tasks. Short lessons get finished, are easy to update and show progress. Across the course, meet the platform minimum: Udemy requires at least 30 minutes of video and 5 lectures, and Skillshare requires at least 10 minutes.
What are Udemy's video requirements? Each video must be at least 720p and under 4 GB, with audio on both channels and in sync and no distracting background noise. A course needs at least 30 minutes of video content and at least 5 separate lectures, and free courses published since March 2020 must be under two hours.
Can I use AI narration for course videos? Often, yes, especially for concept lessons built from a script, but check the platform's current quality guidelines and disclose AI narration in the course description. Listen to every lesson for mispronounced terms, and add a real camera welcome per module so students know who is teaching.
Do I need to show my face in course videos? No. Screen recordings, narrated slides and faceless narrated lessons all work. A short on-camera welcome at the start of the course and each module builds trust, but the lessons themselves can be screen or narration only.
What equipment do I need to record course videos? A USB or lapel microphone, a quiet room, and either a computer with a built-in screen recorder or a phone on a stand by a window. Good audio matters far more than the camera. Free recorders built into macOS and Windows are enough for most courses.
How do I add captions to course videos? Use an AI editor that transcribes the recording and burns in or exports captions, then upload the SRT or VTT file to the course platform and provide the transcript as text. Check technical terms by hand, since speech recognition often gets them wrong.
How do I market an online course with video? Cut 30 to 60-second clips from the lessons for Shorts, Reels, TikTok and LinkedIn, make a 60 to 90-second trailer that states the outcome, and post one educational Short a week from the course material. AI clipping tools select the segments from a long upload automatically.
