Personal Experience with Synthesia.io
I started using Synthesia for one simple reason: I was tired of recording the same video multiple times.
Filming sounds easy until you actually do it consistently. Setting up lights. Fixing audio. Repeating lines. Editing mistakes. It takes time and energy. As someone creating AI-style UGC content, I needed something faster and more predictable.
When I first tried Synthesia, I didn’t expect much. I assumed it would feel robotic. But the setup was straightforward. I picked an avatar, pasted my script, selected a voice, and generated the video. No camera. No microphone. No retakes. That alone saved me hours.
The avatars are not perfect. If you look closely, you can still notice slight stiffness in expressions. Emotional storytelling is limited. But for product demos, SaaS walkthroughs, explainer videos, or affiliate reviews, it works well. In fact, for AI UGC content, the polished digital look fits naturally.
What I appreciate most is the flexibility. If a hook doesn’t work, I rewrite the first few lines and regenerate the video. If I want to test another language, I can do that without hiring voice actors. It makes experimentation easier and less expensive.
That said, I wouldn’t use it for deeply personal content. If your brand depends on strong facial expressions and emotional connection, recording yourself is still more powerful. Synthesia is efficient, but it doesn’t replace real human presence.

How does the video creation process work in Synthesia.io, step by step?
To make a video with Synthesia.io, you start by defining what you want your video to say and achieve.

Can I import my existing content like slides or documents into Synthesia.io to create videos?
Yes, Synthesia.io can transform existing materials into video format.
Rather than starting from scratch, you can upload PowerPoint presentations, PDFs, Word documents, or even plain text files into the platform.
The AI automatically parses your content and breaks it into video scenes for you, turning text into narrated visual sections with appropriate pacing and layout.
Once the initial draft is generated, you retain full control to adjust scripts, timing, avatars, and visual elements scene by scene before final production.
This feature is especially useful for repurposing training materials, internal documents, or presentations into engaging video content without manual recording or editing.
Does Synthesia.io support multilingual video creation and localization?
Absolutely, one of the strengths of Synthesia.io is its multilingual support.
The platform supports over 140–160 languages and dialects, allowing you to generate voiceovers and subtitles in different languages without needing human translators or voice actors for every version. When planning multilingual content, best practice is to create one master video and then duplicate that video for each language you need; you can then replace the script with your translated text while keeping visuals and pacing consistent.
Synthesia’s language tools automatically match the selected voices to your script language, making it much easier to localize content for a global audience in minutes rather than hours.
