How to Make AI Avatar Videos with Synthesia (Step-by-Step)
Creating professional videos without expensive equipment, actors, or filming crews has never been easier. Synthesia, the leading AI avatar video platform, enables anyone to produce polished videos in minutes using realistic AI avatars that speak your script in over 140 languages. Whether you’re creating corporate training content, marketing videos, or educational material, this comprehensive guide walks you through every step of the process.
Over 1 million users have already adopted Synthesia to streamline their video production workflows. The platform eliminates traditional video production bottlenecks—no camera, microphone, lighting setup, or editing skills required. Instead, you write a script, select an avatar, and Synthesia’s AI generates a professional video ready for distribution.
Getting Started: Setting Up Your Synthesia Account
Before you can create your first AI avatar video, you’ll need to establish a Synthesia account. The process is straightforward and takes approximately five minutes.

Visit Synthesia’s website and click the “Create Account” button on the homepage. You’ll have the option to sign up using your email address, Google account, or Microsoft account. Using existing credentials accelerates the process. After entering your information and verifying your email, you’ll be directed to the Synthesia dashboard.
Step 2: Choose Your Plan
Synthesia offers multiple subscription tiers to accommodate different needs and budgets. The Free plan allows limited video creation; the Starter plan ($28/month) includes basic features suitable for individuals and small teams; the Creator plan ($67/month) adds advanced customization options; and the Business plan ($276/month) serves enterprise needs. For testing purposes, the Free tier lets you create one complimentary video to explore the platform’s capabilities before committing financially.
Step 3: Familiarize Yourself with the Dashboard
Upon first login, you’ll see the main dashboard displaying your video projects, templates, and recent creations. The left-hand sidebar contains navigation options including “Videos,” “Templates,” “Avatars,” and “Settings.” Spend a few minutes exploring these sections to understand the platform layout. The interface is intuitive, but knowing where each feature resides saves time when you’re ready to create content.
Creating Your Video Script and Selecting Content Format
A quality script is foundational to an effective AI avatar video. Unlike traditional video production where you can improvise during filming, AI avatar videos require precise scripting because the avatar will speak exactly what you write.
Step 4: Draft Your Script
Before opening Synthesia, compose your script in a text editor or word processor. Keep these principles in mind:
- Clarity and Conciseness: Write as you speak. AI voices perform best with conversational language rather than overly formal text. A two-minute video typically contains 250-300 words.
- Natural Pacing: Include punctuation strategically. Periods signal pauses; semicolons create shorter pauses. Proper punctuation helps the AI voice sound more natural.
- Audience Alignment: Consider your target audience’s comprehension level and adjust vocabulary accordingly. Technical jargon works for expert audiences but may alienate general viewers.
- Call-to-Action: If the video’s purpose is conversion or engagement, include a clear call-to-action near the conclusion.
Example script for a corporate training video: “Welcome to our new customer service protocol. In this three-minute overview, we’ll cover three essential changes to our support process. First, all customer inquiries should be logged in the new CRM system within two hours of receipt. Second, response time expectations have been reduced to 24 hours for standard issues. Third, escalation procedures now require supervisor approval before customer transfer. Let’s examine each change in detail.”
Step 5: Determine Your Video Format
Synthesia supports two primary content input methods: text-based video creation and presentation uploads. For most users, text-based creation is more straightforward. You simply input your script, and Synthesia generates video. For presentation-based content, you can upload a PowerPoint or PDF, and Synthesia will create a video with an avatar presenting your slides. Choose the format matching your content type and workflow preferences.
Selecting and Customizing Your AI Avatar
Synthesia’s avatar selection is one of the platform’s standout features. With 230+ professionally designed avatars available across diverse demographics, ethnicities, and styles, you can find a representative that resonates with your audience.
Step 6: Navigate to the Avatar Selection Interface
In the Synthesia dashboard, click “Create Video” to start a new project. You’ll immediately see the avatar selection screen displaying thumbnail previews of available avatars. Each avatar shows basic information including name, gender presentation, and language compatibility. You can filter avatars by language, appearance, clothing style, and other parameters to narrow your options quickly.
Step 7: Preview Avatar Voice and Appearance
Before finalizing your selection, click on any avatar to hear a sample of their voice. This is crucial—avatar voice quality significantly impacts video professionalism. Some avatars have more natural intonation, clearer pronunciation, or better emotional range than others. Listen to multiple options to identify which voice best suits your content. A professional, calm voice might work for corporate training, while a more energetic voice suits marketing content aimed at younger audiences.
Step 8: Create a Custom Avatar (Optional but Recommended)
For organizations wanting branded content, Synthesia allows custom avatar creation using your own footage. Navigate to “Avatars” in the left sidebar and click “+ Create Avatar,” then select “Personal Avatar.” You’ll upload video footage of yourself (or a colleague) reading a script. Synthesia processes this footage over 24-48 hours to create a personalized avatar matching your appearance.
Requirements for custom avatar creation include a minimum of five minutes of video footage, well-lit recording environment, clear audio without background noise, and multiple angles showing your face and upper body. Custom avatars are available on the Creator ($67/month) and Business ($276/month) plans.
Step 9: Customize Avatar Appearance
After selecting your avatar, you can customize their appearance further. Options include:
- Clothing Color: Change outfit colors to match your brand palette or organizational colors.
- Background: Choose from virtual backgrounds including offices, classrooms, outdoor settings, or branded custom backgrounds.
- Look Name: Save your customization as a named “Look” for future videos, ensuring brand consistency across multiple projects.
- Logo Placement: Add your company logo to the avatar’s clothing or background (Creator and Business plans only).
These customizations ensure your videos maintain visual consistency with your brand identity and message.
Entering Your Script and Configuring Video Settings
With your avatar selected, you’re ready to input your script and configure technical settings that determine how your video renders.
Step 10: Input Your Script Text
In the main video editor, you’ll see a large text box labeled “Enter your script.” Paste or type your prepared script here. Synthesia has a maximum script length of approximately 10,000 characters per video, which typically accommodates 10-15 minutes of video content. If your content exceeds this limit, split it into multiple videos or condense your script.
As you type, Synthesia displays a real-time estimate of video length in the bottom right corner. This helps you gauge whether your script will fit your intended duration. Aim for natural content length rather than padding unnecessarily—viewers can sense artificially extended content.
Step 11: Select Your AI Voice and Language
Synthesia’s voice technology supports 140+ languages and accents, making it invaluable for global organizations. Below your script input area, you’ll see voice selection options. If you selected an avatar, their default voice appears, but you can change it to any available voice. For multilingual videos, you can create versions in different languages without re-recording or creating new avatars.
Voice customization options include:
- Speaking Speed: Adjust from slow (0.75x) to fast (1.5x) to match your content tone and audience comprehension needs.
- Tone/Emotion: Some avatars offer emotional variations—neutral, cheerful, serious—allowing you to match voice tone to content mood.
- Pronunciation Guides: For technical terms, brand names, or proper nouns, you can specify exact pronunciations to avoid AI mispronunciation.
Step 12: Configure Video and Background Settings
Beneath voice settings, configure your video output specifications:
- Video Resolution: Choose between 720p (standard definition) or 1080p (high definition). 1080p is recommended for professional distribution but requires slightly longer rendering time.
- Background Selection: Pick from Synthesia’s library of professional virtual backgrounds or upload your own branded background image.
- Avatar Positioning: Determine whether the avatar occupies the full screen or sits beside your presentation slides (if using presentation format).
- Captions: Enable automatic caption generation in your script’s language. Captions significantly improve accessibility and video performance on social platforms.
Generating, Reviewing, and Exporting Your Video
After configuring all settings, you’re ready to generate your video. This section covers the rendering process, quality review, and export options.
Step 13: Generate Your Video
Click the “Create Video” or “Generate” button (naming varies by interface version) to begin the rendering process. Synthesia processes your script, avatar selection, voice parameters, and background choices to generate your complete video file. Rendering time typically takes 2-5 minutes depending on video length and your current server load. Shorter videos (under 3 minutes) usually render within 2 minutes; longer content may take 5+ minutes.
A progress bar displays the rendering status. You can close the browser window or navigate away during this time—Synthesia will email you when your video is ready, or you can check back in your dashboard.
Step 14: Review Your Video in the Preview Player
Once rendering completes, Synthesia automatically displays your video in an embedded player. Watch your complete video from beginning to end, paying attention to:
- Avatar Synchronization: Does the avatar’s mouth movement match the spoken words? Minor lip-sync delays are normal, but severe misalignment indicates script issues requiring revision.
- Voice Quality: Does the AI voice sound natural? Are there awkward pronunciations or unnatural pauses?
- Pacing: Does the video flow logically? Are there abrupt transitions between concepts?
- Caption Accuracy: If captions are enabled, verify they match your spoken content and display properly throughout the video.
- Background Appropriateness: Does the background enhance or distract from your message?
If issues are identified, you can edit your script, change voice parameters, or select a different avatar, then regenerate the video. Synthesia allows unlimited regenerations, so don’t hesitate to make refinements until your video meets your standards.
Step 15: Download and Export Your Video
When satisfied with your video, click “Download” to export the final file. Synthesia provides your video in MP4 format, compatible with virtually all video platforms and devices. The downloaded file is typically 100-500MB depending on resolution and length.
Export options available include:
- Direct Download: Save to your computer immediately for local editing or storage.
- Cloud Storage Integration: Export directly to Google Drive, Dropbox, or OneDrive for easy team access and backup.
- Social Media Optimization: Generate format-specific versions for YouTube, LinkedIn, Facebook, or Instagram (Creator and Business plans).
- Shareable Link: Create a temporary shareable link for quick video previews without downloading.
Advanced Features and Customization Options
Beyond basic video creation, Synthesia offers advanced features for users wanting greater creative control and professional polish.
Multi-Avatar Videos
Create conversations or interviews featuring multiple avatars. Script sections can be assigned to different avatars, creating a dialogue format. This feature is excellent for creating engaging training content, interview-style explainer videos, or discussion-based educational content. Simply designate which avatar speaks each section using formatting cues in your script.
Template Library
Synthesia provides pre-designed templates for common video types including product demos, customer testimonials, training modules, and marketing explainers. Templates include pre-configured avatars, backgrounds, and script structures. Beginners benefit from templates by learning best practices while accelerating content creation.
Branded Kit Creation
Organizations can create branded kits combining custom avatars, branded backgrounds, color palettes, and logo placement. Team members can then create videos using these branded kits, ensuring visual consistency without requiring extensive customization per video. This feature is particularly valuable for enterprises managing video content across departments.
Video Localization
Create multilingual versions of your videos automatically. Translate your script into any of 140+ supported languages, then generate videos in those languages using the same avatar. The avatar’s lip-sync automatically adjusts to match the new language’s phonetics. This dramatically reduces localization costs for organizations serving global audiences.

Common Mistakes to Avoid
Learning from others’ experiences accelerates your mastery of Synthesia. Here are frequent mistakes beginners encounter:
Script Issues
Writing overly long scripts without considering video length is the most common error. Synthesia’s 10,000-character limit sometimes surprises users accustomed to traditional video scripts. Additionally, scripts with excessive punctuation or unusual formatting confuse the AI voice, resulting in unnatural pacing. Solution: Draft scripts conversationally, use preview estimates to verify length, and test-generate one short video before creating your full project.
Poor Audio Pronunciation
Technical terms, brand names, and proper nouns may be mispronounced by default AI voices. For example, “PostgreSQL” might be pronounced incorrectly. Rather than settling for incorrect pronunciation, use Synthesia’s pronunciation guide feature to specify exact pronunciation. Create a list of challenging terms before generating your video.
Inconsistent Avatar Selection Across Videos
Creating a video series with different avatars each episode confuses viewers expecting consistency. If producing multiple related videos, select the same avatar and create a “Look” to maintain visual consistency. Viewers recognize and relate to consistent presentation.
Ignoring Caption Accuracy
While Synthesia’s automatic captions are generally accurate, errors occasionally occur with specialized terminology or accented speech. Review captions carefully before publishing. Accurate captions improve accessibility and SEO performance for videos on platforms like YouTube.
Neglecting Video Optimization for Distribution Channels
A video perfect for LinkedIn may require different framing, length, or aspect ratio for YouTube or Instagram. Before finalizing your video, consider where you’ll distribute it and generate platform-specific versions if available through your plan tier.
