When it comes to creating videos in Synthesia, the script is just one part of the story. How your video looks, especially your avatar’s outfit and the background, plays a huge role in how your message is received.
If your avatar looks like they belong in the context of your message, and your background supports that story visually, your video instantly feels more relevant, polished, and trustworthy.
Why visuals matter in AI video
Even with an AI presenter, viewers pick up on the same visual cues they would in any video:
Is the speaker dressed appropriately?
Does the background match the message?
Does this look like it was thoughtfully put together?
When visuals align with the content, your message feels clearer and more credible. When they don’t, your video risks feeling generic or mismatched.
Make your Avatar fit the message
Think about how you’d dress a real presenter:
Formal outfits for professional or external communication
Casual looks for internal updates or informal training
Industry-specific clothing (e.g., scrubs, uniforms, lab coats) for authenticity and credibility
When your avatar looks the part, viewers are more likely to stay engaged and take the message seriously.
Set the scene with the right background
Backgrounds do more than fill space — they provide context.
Use a modern office for product demos or sales content
Pick a neutral background to keep focus on the message
Add an industry-specific environment for relevance to the situation

This is a great way to:
Add variety to your edits
Visually reinforce key points from your script
Make your avatar feel like part of a real-world environment
It’s especially powerful in training or promotional content where realism and visual context improve clarity and retention.
