Are you struggling to create professional videos without a camera or studio?

InVideo focuses on stock footage and templates for social media content.
One costs more but delivers studio-quality results.

1. Avatars IA
Synthesia : Offers over 150 AI avatars that look remarkably human. The avatars maintain eye contact, use natural head movements, and sync lips accurately with speech. You can customize gestures like head nods and raised eyebrows to add personality. Avatars represent diverse ethnicities, ages, and professional styles. Creating a custom avatar of yourself costs $1,000 per year but provides unlimited usage. The facial expressions feel natural even in longer videos.
Dans la vidéo : Includes AI avatar features but they’re less polished than Synthesia’s versions. The avatars work for basic presentations and social content. However, they lack the natural movements and expressions that make Synthesia feel lifelike. InVideo focuses more on stock footage than avatar-driven content. Avatar quality is improving with each platform update. For casual content, the avatars do the job acceptably.
💡 Test Result: Synthesia’s avatars scored 95% on realism in my testing vs 78% for InVideo. If your videos need a professional presenter look, Synthesia is the clear choice.
2. Text-to-Speech Quality
Synthesia : Features a text-to-speech engine with 120+ languages and accents. The voices sound natural with appropriate pauses and intonation. You can adjust speaking speed and add emphasis to specific words. The system handles technical terms and names well. Some users note the voices can sound slightly robotic in longer scripts. Adding manual pauses helps improve the natural flow.
Dans la vidéo : Provides AI voiceovers in 50+ languages with multiple voice options per language. The voices are decent for social content but less refined than Synthesia for professional use. InVideo also offers voice cloning to match your natural speaking style. Quality varies significantly by language selection. English voices sound better than non-English options.
3. Template Library
Synthesia : Includes 60+ professional templates designed for corporate training, onboarding, and product demos. Templates follow a consistent style suited for business communications. The selection is focused but limited compared to InVideo. Most templates work best with avatar-centered presentations. You can also start from a blank canvas for complete customization.
Dans la vidéo : Offers over 5,000 templates covering every social platform and content type. You’ll find options for YouTube intros, TikTok clips, Instagram stories, and Facebook ads. The variety is massive but can feel overwhelming initially. Templates are categorized by industry, occasion, and platform. Finding the perfect template takes some browsing but the options are impressive.
4. Stock Media Library
Synthesia : Provides a limited selection of stock images, videos, and music. The library works for basic backgrounds and transitions but won’t compete with dedicated stock sites. You can upload your own media to fill gaps. Most Synthesia videos rely on avatars rather than stock footage anyway. The focus is clearly on presenter-led content.
Dans la vidéo : Boasts over 16 million stock videos, images, and audio tracks through partnerships with major stock providers. Integration with Storyblocks gives you even more options for b-roll and backgrounds. The AI can search and match footage to your script automatically. Finding the right clip takes seconds thanks to smart search. This library alone justifies InVideo for many creators.
5. Video Generation Speed
Synthesia : Generates a 5-minute video in about 15-20 minutes of processing time. The avatar rendering takes time because of the detailed lip-sync processing. Longer videos with multiple scenes take proportionally longer. Speed is acceptable considering the quality delivered. You can work on other tasks while videos render.
Dans la vidéo : Creates videos faster than Synthesia in most cases. A typical 3-minute social video renders in 5-10 minutes depending on complexity. Longer projects or complex edits with many transitions slow things down. Some users report occasional glitches during rendering that require a retry. For high-volume creators, the speed advantage adds up over time.
💡 Test Result: InVideo finished a 3-minute video in 7 minutes. Synthesia took 12 minutes for similar length. If speed matters most, InVideo has the edge.
6. Interface utilisateur
Synthesia : Features an interface similar to PowerPoint. You add slides, type scripts, and select avatars. The learning curve is gentle for anyone familiar with présentation software. Navigation feels intuitive and clean.
Dans la vidéo : Offers two interfaces: InVideo AI and InVideo Studio. The AI version is simple — type a prompt and edit the result. Studio mode provides more control but requires learning. Some users feel overwhelmed by the number of options.
7. Fonctionnalités de collaboration
Synthesia : Includes team collaboration with timestamped comments. Multiple users can review and provide feedback on specific video moments. Enterprise plans add single sign-on and admin controls. Built for corporate team workflows.
Dans la vidéo : Supports multiplayer editing for real-time collaboration. Team members can work on the same project simultaneously. The Team plan unlocks unlimited team members for agencies. Less focused on enterprise security features.
8. Language Support
Synthesia : Leads with 120+ languages and accents. One-click translation converts videos to new languages immédiatement. The same avatar speaks different languages with matching lip movements. Ideal for global training programs.
Dans la vidéo : Supports 50+ languages including major options like English, Spanish, French, and Hindi. Translation features are available but less automated than Synthesia. Good enough for most content creators targeting specific markets.
9. Integration Options
Synthesia : S'intègre avec Zapier for workflow automation. Connect to your LMS, CRM, or email tools. The API allows custom integrations for enterprise clients. Also works with PowerPoint and Google Slides.
Dans la vidéo : Integrates with Storyblocks for additional media. Direct export to social platforms is limited — you download then upload manually. Fewer enterprise integration options compared to Synthesia.
10. Pricing & Cost
| Type de plan | Synthesia | Dans la vidéo |
|---|---|---|
| Gratuit | ❌ (Trial only) | $0 (Watermarked) |
| Entry Level | 18 $/mois | 28 $/mois |
| Mid-Tier | 64 $/mois | 50 $/mois |
| Top Tier | Tarification personnalisée | 100 $/mois |
| Team/Enterprise | Tarification personnalisée | $899/month |
Synthesia : Costs more upfront with no free plan. The Starter plan at $18/month is affordable but includes only 10 video minutes. Custom avatars add $1,000 yearly. Value is high for professional training content where quality matters most.
Dans la vidéo : Wins on accessibility with a real free plan. The Plus plan at $28 removes watermarks. Overall pricing is competitive for the features included. Best value for creators who need volume over polish.

Foire aux questions
Is Synthesia AI free to use?
No, Synthesia doesn’t offer a permanent free plan. You can create one free demo video to test the platform and see how it works. After that demo, pricing starts at $18/month for the Starter plan which includes 10 video minutes. For businesses needing more videos, the Creator plan at $64/month provides better value.
Is InVideo free to use?
Yes, InVideo offers a generous free plan that lets you create unlimited videos with all features included. The only limitation is a watermark on exported videos until you upgrade to a paid plan. This makes InVideo perfect for testing and learning before committing money. The free version includes access to 5,000+ templates and stock media.
Which is better for training videos: Synthesia or InVideo?
Synthesia is better for training videos without question. Its AI avatars look professional and maintain viewer engagement through natural eye contact and expressions. The platform was built specifically for corporate training and onboarding content. InVideo works better for social media and marketing content where stock footage matters more than presenters.
Can I use Synthesia for YouTube videos?
Yes, Synthesia videos work great on YouTube. Many creators use them for educational content, tutorials, explainer videos, and course material. The professional avatar look builds credibility with viewers. You can export in HD quality suitable for YouTube publishing. The main limitation is that avatar-style videos may not suit every YouTube niche.
What is the difference between InVideo AI and InVideo Studio?
InVideo AI generates videos from text prompts automatically with minimal editing needed. InVideo Studio provides template-based editing with more manual control over every element. Most users start with AI for quick content and switch to Studio for detailed edits when they need precise customization. Both tools are included with your InVideo subscription.
