Convert blog posts into engaging AI videos in 140+ languages.
Last month, I found myself staring at our company blog analytics with a mix of pride and frustration. The content was solid, with well-researched posts that our team had spent hours crafting, but the reach was plateauing. The same few hundred readers would engage, but we weren't breaking through to new audiences.
That's when I stumbled upon Synthesia's AI video creation tool. On a whim, I decided to convert one of our popular blog posts into a video. The process took me less than 15 minutes, and the results? That single video brought in more new leads in a week than the original blog post had in a month.
Since then, I've been regularly turning our blog content into videos, expanding our reach across platforms where our audience prefers watching to reading.
Let me walk you through exactly how I do it.
Why turn blog posts into video?
The stats don't lie: according to Wyzowl, 73% of consumers prefer watching short videos to learn about products or services. I've experienced this firsthand with our newsletter. Its click-through rates jumped by 26% when we started including video thumbnails alongside blog links.
What I've found most valuable is how video helps us reach people who never would have read our blog in the first place. Our target audience includes busy professionals who often don't have time to read a 1,500-word article but will gladly watch a 3-minute video covering the same content during their commute.
Before implementing video, our average content engagement time was about 2 minutes. Now, with complementary videos, we're seeing combined engagement times of over 5 minutes per piece of content. That extra attention translates directly to more conversions.
Step-by-step: How I use Synthesia to convert blog posts to video
1. Start with a well-structured blog post
I've learned that not every blog post converts equally well to video. Posts with clear sections, subheadings, and a logical flow work best. Before starting, I sometimes tweak the original post, breaking up paragraphs and ensuring there's a clear structure.
For example, when converting our "5 Customer Retention Strategies" post, I first reorganized it to make sure each strategy had its own distinct section with a clear takeaway. Then I simply copied the URL.
2. Open Synthesia's AI video assistant
After logging into my Synthesia dashboard, I head straight to the "AI video assistant" feature and click "URL". This is where the magic happens. I paste in the blog URL and watch as the AI analyzes the content and automatically drafts a video script.
The first time I saw this, I was genuinely surprised, as it it pulled out the key points while maintaining the core message of our post. No need to write anything from scratch!
3. Tweak and refine the script
While the AI does an impressive job, I always take a few minutes to review the draft script. Sometimes it misses nuances or includes sections that don't translate well to video.
I've developed a habit of making dense, technical sections more conversational. For instance, instead of "Implementation of this strategy resulted in a 24% increase in customer satisfaction scores," I might change it to "When we tried this approach, our customer satisfaction jumped by 24%."
Pro Tip: I keep each scene focused on one main point. If I notice a scene covering multiple concepts, I split it up. This dramatically improves viewer retention.
4. Choose the right video template
Synthesia offers various templates optimized for different purposes. For LinkedIn, I use their professional presentation templates. For Instagram, I opt for square formats with more visual elements and less text.
The template selection has a significant impact on engagement. When we shared the same content using a training-style template versus a social media template on Twitter, the social template got 3x more shares.
5. Personalize with avatars, voices, and visuals
This is where I add our brand personality. I select an AI avatar that represents our company well and is professional but approachable. For voice, I choose one that matches our brand tone (slightly conversational but authoritative).
I've created a brand kit in Synthesia with our logo, color scheme, and preferred fonts. This ensures every video looks and feels consistent with our other marketing materials, which has significantly improved our brand recognition.
6. Fine-tune slides for impact
The default slides Synthesia creates are good, but I always make adjustments:
- Shortening text on busy slides
- Adding emphasis to key statistics or quotes
- Rearranging the order of some points for better flow
I constantly preview the video as I make these changes. My goal is to keep it engaging enough that I would want to watch it myself.
7. Translate or localize (optional)
Since we have customers in several European countries, I sometimes use the auto-translate feature to create versions in Spanish and French. This has opened up entirely new audience segments with minimal additional effort.
Even when I don't translate, I always add captions. They've improved our accessibility and allow people to watch without sound in public places.
8. Generate and download the video
With everything set, I click "Generate" and wait just a few minutes for Synthesia to create the video. Once it's ready, I download the MP4 file and upload it to our various platforms.
What I love most is the ability to go back and make updates. When information changes, I don't create a whole new video. Instead I just edit the existing project and regenerate it.
Best practices & tips I've learned
After creating dozens of these videos, I've picked up some useful insights:
- The sweet spot for our audience is 2-3 minutes - anything longer sees a drop-off in completion rates
- Adding customer quotes or testimonials as text overlays increases credibility
- Using a mix of avatar scenes and full-screen graphics keeps the visual experience interesting
- Our highest-performing videos use the pattern: problem → solution → proof → action step
I've had particular success using Synthesia for product tutorials, industry news summaries, and quick tips videos. These formats have generated the most shares and comments.
It's easier than you think
When I first considered adding video to our content mix, I imagined weeks of production time, hiring videographers, or learning complex editing software. Synthesia changed that calculation entirely.
Now, video is an integrated part of our content strategy, not an occasional luxury. Every important blog post gets a video companion, expanding our reach and engaging audiences who would never have discovered us otherwise.
If you're sitting on a goldmine of blog content that could reach new audiences through video, I encourage you to give this process a try. The barrier to entry is lower than it's ever been, and the potential upside is enormous.
