August 23, 2026

Creating a talking-head video usually requires a studio, but Synthesys generates realistic videos with AI avatars in just a few steps. This guide walks you through creating professional video content with Synthesys, from script to final render.

Why Use AI Avatars for Video

Video is highly engaging, but producing it at scale is expensive and slow. Synthesys lets you create consistent, studio-quality presenters without actors or cameras, making it ideal for marketing, training, and sales teams.

Step 1: Pick an Avatar

Log in to Synthesys and browse the avatar library. Choose a presenter whose appearance and style fit your brand and audience. You can also create a custom avatar to represent your company.

Step 2: Write or Upload Your Script

Write your video script directly in the editor or paste an existing script. Keep sentences short and conversational, as this produces more natural AI narration. You can also use the AI script writer inside Synthesys to generate copy.

Step 3: Select a Voice and Language

Choose a text-to-speech voice that matches your avatar and message. Synthesys supports many languages and accents, so you can create multilingual videos for global campaigns.

Step 4: Preview and Adjust

Preview your video to check lip-sync, pacing, and voice quality. Adjust the script or voice settings as needed. Synthesys lets you fine-tune the performance before rendering the final version.

Step 5: Render and Download

Render your video in the aspect ratio you need for your platform, such as landscape for YouTube or vertical for social media. Download the file and publish it on your channels.

Pro Tips

Keep your script under a few minutes to hold viewer attention. Use a consistent avatar and voice to build brand recognition. Test different avatars and voices to find the combination that engages your audience best.

With Synthesys, you can produce high-quality presenter videos quickly and affordably, giving your marketing and training content a professional edge.
