How I Create Videos Using Synthesia AI Video Generator (2025 Edition)
If you had told me two years ago that I'd be publishing full video content weekly without touching a camera or microphone, I would have laughed. But now? That’s exactly what I do — thanks to Synthesia AI Video Generator.
This post is not about theory — it’s about how I personally use Synthesia in my workflow to save hours, cut costs, and create professional video content for my tech blog and YouTube channel.
Why I Switched to AI Video Creation
Before Synthesia, I spent hours recording, editing, and voicing over videos. I was burned out, especially with tight turnarounds and inconsistent lighting/audio issues.
After testing a few AI tools, I landed on Synthesia — an AI video generation platform that lets you convert text into realistic videos using digital avatars. No equipment needed. Just paste your script, choose an avatar, and export.
Honestly, I was shocked by how natural the avatars looked. And for explainer-style tech content? It’s perfect.
My Workflow With Synthesia AI (Step-by-Step)
-
Script Creation with ChatGPT: I first use ChatGPT to generate a structured script for my video, tailored for my niche.
-
Polishing the Script: I review the script, cut the fluff, and make sure it sounds natural when spoken. Pro tip: Keep sentences under 15 words for smooth delivery.
-
Login to Synthesia.io: After logging in, I choose from dozens of avatars — from business-casual to techy personas.
-
Upload the Script: I paste the script into Synthesia’s slide editor and assign different segments to different avatars if needed.
-
Customize Background: I use my brand colors, add my website, and include supporting visuals like graphs, screenshots, or animations.
-
Generate & Download: Once done, Synthesia processes the video (usually under 10 minutes) and I download it in HD.
This entire workflow — from idea to finished video — takes less than 1 hour.
Real-World Use Cases I’ve Tried
YouTube Tutorials
With Synthesia, I’ve published 15+ tutorial videos in the last 3 months. My audience loves the clean presentation, and I didn’t need to show my face once.
Email Marketing Explainers
I embed Synthesia videos in my emails (using tools like ActiveCampaign). This increases open rates and engagement.
Product Reviews & Comparisons
I used it to create a visual comparison between MailEmpire AI vs. other marketing tools — a blog now ranking top 3 in Google. See my related post: Marketing Automation for Salesforce.
My Honest Thoughts After 90 Days of Use
Pros:
- Fast production — zero camera or editing skills required
- Professional look — great for building trust
- Multilingual support — ideal for global reach
Cons:
- Can feel robotic for long-form content
- Some avatars are more expressive than others
- Monthly pricing can be steep for beginners
That said, the ROI is absolutely worth it if you publish content regularly.
What About Pricing?
I use Synthesia’s Starter Plan, which is enough for most creators. For more flexibility (custom avatars, team access), consider the Creator Plan.
Final Thoughts: Is Synthesia AI Video Generator Worth It?
If you’re a content creator, startup founder, educator, or marketer — and you’re looking to scale your content without scaling your workload — Synthesia is a game-changer.
In my case, it helped me go from publishing 1 video/month to 8+ videos/month across platforms.
Pair it with tools like ChatGPT (for scriptwriting), Canva (for visuals), and MailEmpire (for distribution), and you have a mini production studio in your laptop.
Let me know if you try Synthesia or want my free video script template — I’d love to hear what you’re building.
