Create AI videos with 230+ avatars in 140+ languages.
Convert your webpages into engaging AI videos in 140+ languages.
Last month, I found myself drowning in content. Our marketing team had produced dozens of excellent blog posts, help articles, and product pages, but they weren't getting the engagement we hoped for. I knew video was the answer. After all, people retain 95% of a message when they watch it in a video compared to just 10% when reading text, but the thought of scripting, filming, and editing videos for all that content made me want to curl up under my desk.
That's when I stumbled upon Synthesia's URL-to-video feature. What would have taken me weeks of work suddenly became possible in minutes. I've since transformed over 30 webpages into engaging videos, and I'm excited to share exactly how you can do the same.
Step-by-step: from webpage/URL to AI video
1. Preparing your webpage or URL
Not all webpages are created equal when it comes to video conversion. I've learned through trial and error that the best candidates have:
- Clear, well-structured content with distinct sections
- A logical flow of information
- Minimal clutter like ads, pop-ups, or excessive links
I typically start with high-value content like product pages or help center articles. For example, last week I converted our "Getting Started" guide, which was buried in our help center but contained valuable onboarding information. The resulting video now welcomes every new customer to our platform.
2. Accessing Synthesia's AI video assistant
After logging into my Synthesia account, I navigate to the AI video assistant section (it's right on the dashboard). There's a simple field where I paste the URL I want to convert. The first time I tried this with our product comparison page, I was genuinely surprised at how quickly the AI analyzed the content and prepared a draft summary.
The system doesn't just copy-paste your content, it intelligently extracts the most important points and organizes them into a logical video structure. It's like having a content strategist and video producer rolled into one.
3. Refining the AI's summary and video structure
This is where the magic happens. Synthesia presents me with an AI-generated summary and slide breakdown based on the webpage content. I can then:
- Adjust the target audience (I usually select "general audience" for social media or "professional" for B2B content)
- Set my preferred tone (conversational works best for most of my videos)
- Choose the length (I find 1-2 minutes optimal for social sharing)
- Reorganize sections by dragging and dropping
One lesson I've learned: limit each scene to one key idea. In my first videos, I tried cramming too much information into each slide, which made them harder to follow. Now I break things down into bite-sized chunks, which dramatically improves viewer retention.
4. Choosing the right video template
Synthesia offers dozens of templates, and selecting the right one makes a huge difference. For our LinkedIn content, I use professional templates with clean lines and subtle animations. For more casual platforms like Instagram, I choose templates with bolder colors and dynamic transitions.
Last month, I created the same product announcement video in three different templates for different platforms. Our LinkedIn version had 3x the engagement of our previous text-only posts.
5. Selecting and customizing avatars and voice
This might be my favorite part of the process. Synthesia offers a diverse range of realistic AI avatars with natural speech patterns and expressions. I typically select avatars that reflect our company's diversity and match the content's tone.
For longer videos, I've found that switching between 2-3 different avatars keeps viewers engaged. For our product tutorials, I use Anna, who has a friendly but professional demeanor, while for more technical content, I often choose Michael, who conveys authority well.
The AI voices sound remarkably human - a far cry from the robotic text-to-speech avatars I was using before. You can even adjust the speaking pace and emphasis on key words.
6. Editing script, slides, and visuals
While the AI does an impressive job with the initial script, I always review and edit for our brand voice. I typically:
- Shorten sentences for better flow
- Add transition phrases between sections
- Include our standard calls-to-action
The visual editor lets me add our logo, product screenshots, and even charts from the original webpage. Recently, I incorporated animated graphs from our pricing page, which helped visualize the value proposition much more effectively than static text ever could.
7. Localizing and making the video accessible
One of the unexpected benefits I've discovered is how easy it is to create multilingual versions of our videos. With a few clicks, I can translate and regenerate the entire video in Spanish for our Latin American market or German for our European customers.
I always enable auto-captions, which has significantly improved our accessibility and allows people to watch our videos in sound-sensitive environments. Our engagement metrics showed a 22% increase after we started consistently adding captions.
8. Generating and exporting the video
Once everything is set, I click "Generate," and within minutes (seriously, it's that fast), Synthesia produces a polished video. I can download the MP4 file directly or share via a link.
If I spot an error or want to make a change, I don't need to start from scratch. I just edit the specific section and regenerate, which is something that would take hours in traditional video editing.
Best practices & extra tips
Script quality
The AI gives you a great starting point, but I always review for our specific terminology and tone. I've created a simple checklist I run through:
- Is this how we would say it?
- Have we removed unnecessary jargon?
- Does it sound conversational rather than robotic?
Branding consistency
I've uploaded our brand kit to Synthesia, including our logo, color palette, and fonts. This ensures every video looks and feels like part of our brand family, regardless of who creates it or which template we use.
Reuse and revision
Our product features change frequently, and before Synthesia, updating videos was a nightmare. Now, when we launch a new feature, I can update the corresponding video in minutes rather than scheduling a new video shoot.
Ideal use cases
I've had the most success converting:
- Tutorial articles into step-by-step video guides
- Complex pricing pages into clear video explanations
- Customer testimonials into engaging video stories
- Monthly blog posts into weekly social video content
Support & resources
Whenever I get stuck, Synthesia's knowledge base and academy have been invaluable.
Conclusion
Converting webpages to videos used to be a luxury only big companies with video teams could afford. Now, I can transform any piece of content into an engaging video in minutes, not days. This has allowed us to reach audiences who never engage with written content and breathe new life into our existing materials.
The best part? I'm not a video expert. Before discovering this tool, my video editing skills were limited to trimming clips on my iPhone. If I can do it, trust me, you can too.
