How to Convert Training Materials to Video with AI

Learning and Development EvangelistΒ at Synthesia

Convert PDFs, PowerPoints, and Docs into engaging videos in 160+ languages.

If you're in L&D, you probably have a content library that's underutilized. And I'm not just talking about eLearning courses that no one finishes. I'm talking about content sitting in PowerPoint decks, PDFs, Word docs, and internal wikis.

When teams come to us, it's often because they're sitting on a gold mine of institutional knowledge that's stuck in formats employees aren't referencing. So they want to turn their training materials into engaging videos, and quickly.

But here's the reality. Converting a text-heavy, boring PowerPoint into a video will give you a bad training video. That's because engagement is correlated with effective learning design. And even AI can't turn poorly designed content into an effective training video.

Here's how to do it well.

Step 1: Confirm the content is worth converting

You've probably heard "garbage in, garbage out" applied to AI. If you put in poorly designed content, you're going to get a well-produced version of the same problem.

That's why, before you convert anything into a video, you need to do a quick quality check. Ask one question of every piece of content: does this have a clear learning objective and measurable outcome?

Decision tree, should your training content be a video?
A quick check before you convert anything

Every video you create should be grounded in a learning objective and performance outcome. You can use a template like this:Β 

This video is for [specific role] who currently [context or gap]. After watching, [specific role] should be able to [observable action] so that [business outcome].

If your content doesn't pass that bar, ask yourself: is it worth redesigning before converting? If yes, proceed. If no, that's okay. Not everything needs to be a video.

How long should a training video be?

Keep training videos concise. A quick explainer may only need to be a microlearning that's 90 seconds long. A more detailed process walkthrough might run 8 minutes. What matters is that each video covers one clear objective.

That means a 60-slide deck probably shouldn't become a single video. Either plan for substantial editing, or plan to create a series of videos.

One thing worth knowing: a recording of a workshop session and a training video are not the same thing. A recording captures a conversation. A training video is designed around a single outcome. Converting one into the other takes more editing than most people expect. Video-based learning works because of how it's designed.

Step 2. Generate an outline

Once you've confirmed your content is worth converting, it's time to generate an outline. Go to our AI video generator and upload a file, like a one-page document outlining the key reminders from an SOP.

If you're interested in following along, here's an example of a PDF training that I've converted into a video below.

After you upload your file and click generate, you'll land in our AI Assistant, which builds an outline like the one below. You can edit the text or delete entire scenes before moving on.

How this works for different file types

PowerPoint: Each slide becomes its own scene. If you turn on "Convert speaker notes into script" during import, your speaker notes are pulled in as the script for each scene automatically. It's worth adding notes before uploading if your deck doesn't have them.

Google Slides: Export to PowerPoint first (File β†’ Download β†’ Microsoft PowerPoint), since Google Slides doesn't support a direct upload today. From there, it imports the same way a PowerPoint deck would, including speaker notes.

Word docs: Upload directly. Synthesia analyzes the content and breaks it into logical scenes automatically. There's a 4,500-word limit per document, so if you're working with a long file, plan to split it into a short series.

Google Docs: Export as a Word document first (File β†’ Download β†’ Microsoft Word), since Google Docs doesn't support a direct upload today. From there, it imports the same way a Word doc would.

Step 3: Create your first draft

When you click "Continue to editor," you'll land in Storyboard, Synthesia's script-focused view within the editor. This shows you what the AI has generated based on the input you've provided. In my example, there are no visuals, only text, so the AI will recommend an avatar as well as images, motion graphics, b-rolls, and more for my scenes.

I can give the Assistant feedback by chatting in the sidebar, or switch to Canvas to directly modify my scenes.

Step 4: Choose your avatar

With a draft ready, it's up to you what to focus on next. Some people like to start with their avatar, since they guide the viewer through the video. You can customize their appearance (branded puffer vests, anyone?), pose, and even location to align with your workplace. I've selected Inna for my training video, and am using her voice, which is described as "Encouraging".

Customize your avatar

Pay close attention to their tone, accent, and pronunciation. If your company has a name like ours, you'll want to standardize how that gets said across your content.

You can also go avatar-free and use narration only. Having an avatar onscreen adds to cognitive load, so for dense procedural content it's worth considering.

Step 5. Customize your scenes

Next, you can direct your attention to customizing the scenes. Think one idea per scene. If you want to add any visualizations, like motion graphics or B-roll, or interactivity, remember to keep attention focused.

Preview your video before generating, and double-check that everything from the pronunciation to the flow makes sense.Β 

Preview your scenes

Some generated assets may appear as placeholders or low-fidelity previews until you generate the final video. Here's an example of how IΒ converted the PDFΒ to video.

Step 6. Publish and share

When you've generated your video, you can localize it into over 160 languages with a few clicks. If you’re localizing videos, be sure to include native speakers when you conduct any pilots.Β 

Once you're satisfied with your video, you'll want to publish it and work through a few decisions.

  1. Do you need to localize the video? (If so, follow these localization instructions.)
  2. Where will the video live (e.g., an LMS), and how will employees find it?
  3. Who will have access, and what happens when it's shared?
  4. How will you update content without creating confusion or outdated versions?

Each of these decisions will impact your measurement goals (more on that next).Β 

If you want to see how a company transformed their content library, read about how BD Rowa, a pharmacy automation and robotics company, cut content production time by 75% by transitioning from slide decks and emailed updates to training videos.

Step 7: Measure the impact

Before you try to convert an entire content library into video, I highly recommend evaluating whether the transition to video is worth it for your organization. Often, I find users are so excited by the possibilities of quickly creating training videos that they forget to measure if the transition made any impact.

So here's how to do that. First, go back to your learning objective and performance outcome statement (the bolded one I told you to fill in earlier). Then, identify a few signals that you're meeting expectations.

A quick A/B test worth running

Host the PDF and the video in a trackable format (whether that's xAPI or SCORM, in an LMS or headless platform) and see which gets more clicks. For the video, also check how many people complete it.

Then partner with the team to understand if employees are following the new workflow, where the process is breaking down, and whether the group using the PDF versus the video are better following instructions. Finally, tie that to a business outcome. Ask the team in charge what their leadership cares about. This is what I call good enough measurement.

Remember, you don't want to replace one content library that no one uses with another one. The entire point of converting content into video is to explore whether another medium is more impactful for your employees.

If you want to talk to our team about transitioning a content library, or any other content challenges you're facing, book some time.

Frequently asked questions

Can AI make a training video from a PDF, DOC, or PPT?

Yes. You can upload your PDF, Word document, or PowerPoint into Synthesia's video generator to generate a first draft of a training video. That being said, the quality of your output will depend on the structure of your document or slides.Β 

If they are grounded in effective learning design (e.g., they have a clear objective, are well-structured, and progress towards an outcome), then the quality of the first draft will be better.

Will AI change the meaning of my training content?

No. Synthesia's AI Assistant will generate a draft based on the inputs you share. That being said, AI can make mistakes. You should always verify and review the content generated before accepting it as accurate. Nothing should be published without a human review.

Can I edit the script, scenes, or their order after AI generates the video?

Yes. You can edit the script, reorder or edit individual scenes, and adjust pacing before generating anything final. If you need to make changes after publishing, updating the video saves as a new version, so you always have a record of what changed.

How do you make a training video from a PowerPoint?

First, make sure your deck is training-ready: give it a clear structure, keep speaker notes relevant (they'll be adapted into the avatar's script), and rework any text-heavy slides (walls of text don't adapt well to video).

The better the quality of your PPT, the better the quality of your first draft from Synthesia's AI video generator. If you'd rather not rework the deck first, you can upload it as-is and spend more time editing inside the platform instead β€” either approach works, it's just a trade-off between upfront prep and in-platform editing.

How do I turn a long PDF into a video course?

To turn a long PDF into a video course, start by identifying learning objectives. One objective per video is a good rule of thumb. A 50-page document might contain 5–10 distinct objectives, sometimes more.

An LLM can help speed this up. Try a prompt like: "You are an experienced instructional designer. Read this document and identify 5–10 distinct learning objectives, each specific enough to become its own short video."

Once you've identified the learning objectives you want to keep, use the ADDIE framework to structure the full course, applying the same one-objective-per-video approach to each video within it.

Note:Β Our AI video generator limits document uploads to 4,500 words.

How do I add interactive elements like quizzes or branching to my training videos?

In Synthesia, you can add a variety of interactive components, like knowledge checks, branching scenarios, and clickable buttons.

You can learn more about what makes a training video interactive, and find step-by-step instructions for adding interactivity in our documentation.

What metrics should I track to measure the impact of converting training materials into video?

Start with your learning objective and performance outcome. Figure out what behavior you were trying to change and how you can measure it. You’re looking for a snapshot measurement and an impact measurement, something you can get shortly after launching the video (e.g., completion rates or passing rates on an assessment), plus a business outcome.

For the latter, talk to your stakeholders to understand what KPIs they care about and how you can establish a baseline to determine whether or not your training materials impacted that metric.
