The fastest way to create a course marketing video with AI: write a script in ChatGPT, record and edit it in Descript, add branded graphics in Canva, then export multiple formats for each platform. The entire process takes under two hours once you have done it once, and it replaces a workflow that used to require a videographer, an editor, and a graphic designer. You do not need any of those people. You need your expertise, a decent microphone, and these three tools.
What you’ll walk away with:
- A course promotional video showcasing your teaching style
- Multiple format exports optimized for different platforms
- A repeatable workflow without professional equipment
Why AI for marketing videos
Most course creators never make a marketing video. They know they should — video outperforms every other content format for engagement and trust-building — but the production process feels overwhelming. Writing a script is hard. Recording feels awkward. Editing requires software they have never used. Adding graphics means learning yet another tool. So the video never gets made, and they rely on text and static images to sell a course that is inherently about the experience of learning from them.
AI changes the math on each of these steps. ChatGPT can draft a script structure in minutes. Descript lets you edit video by editing text — delete a sentence from the transcript and the corresponding video disappears. Canva provides templates that turn a plain recording into something that looks professionally branded. None of these tools eliminate the need for your judgment. All of them eliminate the technical barriers that kept the video from existing in the first place.
Research from Wyzowl's annual video marketing survey consistently finds that over 80% of marketers say video directly increases sales. For course creators, the effect is even more pronounced because your product is you teaching. A two-minute video where you explain a concept from your course gives prospective students something no sales page can: a real preview of what learning from you actually feels like.
Step by step: script to published video
Prompt ChatGPT for a video script
Start with a clear brief. Tell ChatGPT who your course is for, what transformation it delivers, and what you want this specific video to accomplish. A launch announcement video has different goals than a testimonial compilation or a "what you'll learn" overview. Ask for a script that runs 150 to 250 words for a 60 to 90 second video. Include a voice note: paste a paragraph of your own writing and tell ChatGPT to match that tone, avoiding hype language, countdown urgency, and phrases like "don't miss out."
The script should follow a simple structure: open with the problem your students face, describe what changes when they go through your course, and end with a clear next step. That is all a marketing video needs to do. ChatGPT will give you a workable draft. Your job is to rewrite any line that does not sound like something you would actually say out loud.
Record in Descript
Open Descript and use its built-in recorder. You can record with your webcam, screen share, or both. Read your script naturally — Descript will generate a full transcript automatically, so you do not need to be perfect on the first take. If you stumble on a line, pause, and say it again. You will clean it up in the next step.
A quiet room and a USB microphone are enough. You do not need studio lighting or a professional backdrop. Descript's AI features will handle audio cleanup. What matters is that you sound like yourself — relaxed, knowledgeable, talking to one person rather than performing for a crowd.
Edit with AI features in Descript
This is where Descript changes the game. Your recording appears as a text transcript. Delete a word or sentence from the transcript and the corresponding audio and video are removed automatically. Use Descript's filler word removal to strip out every "um," "uh," and "you know" in one click. Apply Studio Sound to clean up background noise and normalize your audio levels. If you recorded multiple takes of the same line, keep the best one by deleting the others from the transcript.
The result is a clean, tight recording that sounds polished without sounding over-produced. The text-based editing approach means you spend minutes editing instead of hours learning timeline-based software.
Add branded graphics in Canva
Export your edited video from Descript, then bring it into Canva. Use one of Canva's video templates as a starting point — there are templates designed specifically for course promos, social ads, and testimonial videos. Add your logo, your course title, a subtitle with the key transformation, and any text overlays that reinforce the main message. Canva's auto-caption feature adds readable subtitles, which matter because most social video is initially watched on mute.
Keep the graphics simple. A lower-third with your name and course title, a brief text hook in the first three seconds, and a closing card with a URL or CTA. Over- designing a marketing video makes it look like an ad. Under-designing it makes it look unfinished. One or two branded elements is the right balance.
Create multiple formats
One recording should produce at least three outputs. Use Canva to resize your video: 16:9 landscape for YouTube and your course landing page, 9:16 vertical for Instagram Reels and YouTube Shorts, and 1:1 square for LinkedIn and email thumbnails. You do not need to re-record or re-edit anything — Canva handles the reframing. Adjust the text positioning for each format so nothing gets cropped.
Distribute with context
Post each version on its platform with a caption that adds value beyond the video itself. A line about what inspired the course, a question for the audience, or a brief story that connects to the video's topic. Include a link to your course page. Do not rely on the video alone to drive enrollment — the caption, the pinned comment, and the bio link all work together.
The human layer
AI handles the script scaffolding, the audio cleanup, and the graphic templates. What it cannot handle is the reason someone should care. The moment in your video that actually converts a viewer into a student is almost never the cleanest edit or the sharpest graphic. It is the sentence where your real enthusiasm for the subject comes through. It is the specific example from your teaching experience that no AI could generate because no AI has your experience.
Use AI to remove the friction from production. Then make sure the substance — your teaching perspective, your real results, your direct description of what students will gain — is unmistakably yours.
Course creator tips
- Start with your best teaching moment, not a sales pitch. Open your video with a real insight or practical tip from your course. This shows prospective students how you teach, which builds more trust than any promotional language. Save the enrollment CTA for the last ten seconds.
- Record three versions of your opening line. The first sentence determines whether someone keeps watching. Record a few variations and pick the one that sounds most natural. Descript makes this easy — just delete the takes you do not want from the transcript.
- Repurpose before you create from scratch. If you already have course lesson recordings, pull a two-minute segment that works as a standalone marketing clip. Adding a branded intro and outro in Canva turns existing content into fresh marketing material without another recording session.
What it gets wrong
ChatGPT scripts default to a promotional tone that sounds like every other marketing video on the internet. Phrases like "are you ready to transform your life" and "this course will change everything" will appear in the first draft no matter what instructions you give. Rewrite them. Your prospective students have heard those phrases thousands of times and they have learned to ignore them. Specificity is more persuasive than enthusiasm.
Descript's AI editing is excellent for cleanup but can occasionally remove pauses that served a purpose — a beat before an important point, a moment of natural emphasis. Listen to the edited version all the way through and restore any pauses that made the delivery feel more human.
Canva templates can make every video look the same if you use them without modification. Change the colors to match your brand, swap the default fonts, and resist the urge to use every animation option available. A video that looks like a Canva template tells viewers you spent ten minutes on it. A video with your own branding and restrained design tells them you are serious about your course.
Frequently asked questions
Do I need to be on camera for marketing videos?
You do not need to be on camera, but it helps. Talking-head video builds trust faster than slides or text animations because prospective students see who they will be learning from. If you are not comfortable on camera, start with a voice-over approach using screen recordings or Canva animations. Many course creators ease into camera presence over time once they see how much stronger the connection is.
How long should a course marketing video be?
For social platforms, aim for 30 to 90 seconds. For a sales page or course landing page, two to four minutes works well because visitors have already expressed interest by navigating there. The governing principle is the same as any teaching: say what needs to be said and stop. A 45-second video that delivers one clear idea outperforms a three-minute video that wanders.
Can I use these tools if I have no video editing experience?
Yes. Descript is designed around text-based editing, so if you can edit a document you can edit a video. Canva uses drag-and-drop templates that require no design training. The learning curve for both is measured in hours, not weeks. The AI features in each tool handle the technically difficult parts like noise removal, background replacement, and caption generation.
Where your videos send people
Every marketing video ends with a next step — a link in the description, a URL on the closing card, a "check the link in my bio" call to action. That link points to your course page. When someone clicks through after watching you teach for 90 seconds, they should land somewhere that feels just as straightforward: a clear description of what they'll learn, a simple way to enroll, and no friction between interest and action.
Ruzuku's course builder gives you that landing experience out of the box — a sales page, enrollment, payment, and your full course all in one place. No stitching together separate tools for each piece. Your video does the hard work of earning attention. Your course platform handles everything that comes after the click.
