Mejores características de Synthesia

I’ve tested dozens of video creation tools. Here are the features that make Synthesia stand out.

1. Avatares de IA

Synthesia offers over 240 ai avatars you can use in your videos.

Each avatar looks like a real person. You pick the gender, age, and style that fits your brand.

The avatar quality keeps getting better. The latest models show natural facial expressions and head movements.

You can also create a custom avatar based on your own likeness. This costs $1,000/year. But it means your face shows up in every video — without you recording a single thing.

Users can even customize avatar performances by adding gestures like head nods and raised eyebrows.

2. Texto a voz

The text to speech engine supports 140+ languages and accents.

You type your script. Synthesia turns it into natural-sounding ai voices.

You can change the voice and language at any time. You can add pauses for emphasis.

The platform also offers AI clonación de voz. Record a short sample. Then your own voice reads every script going forward.

Not gonna lie — the ai generated voices still sound slightly robotic in some accents. But for training and internal communications, they work well.

3. Plantillas personalizables

Synthesia gives you 60+ professional templates to start with.

Or you can start from a blank canvas.

Each template looks clean and polished. Pick one, swap the text, choose your avatar, and you’re done.

You can also turn a powerpoint presentation into a video. Upload your slide deck and Synthesia converts it — keeping your original design. Speaker notes become the script automatically.

4. Editor de vídeo con IA

The user interface feels like making powerpoint presentaciones.

You drag and drop elements. Add text, images, and screen recordings.

The editor lets you upload your own media — logos, backgrounds, and brand colors.

You can edit any video without starting over. Change a word, swap an avatar, or update a scene. The tool handles the rest.

This makes video making fast even for people with zero editing skills.

5. Colaboración y compartición

Your team can work on videos together.

The platform allows team members to comment on videos linked to specific timestamps.

Share draft videos with stakeholders for feedback. Make changes in real time.

This is a huge win for creating corporate training content. No more email chains with feedback. Everything lives inside the platform.

6. Asistente de video con IA

Don’t know what to say? The AI asistente Escribe tu guion por ti.

Tell it your topic and target audience. It drafts a full script in seconds.

You can also paste a blog post or document. Synthesia turns it into video content automatically.

This feature alone saves time — especially when you need to create videos from existing training product materials.

7. Grabador de pantalla con IA

Need to make a demo or product walkthrough?

The built-in screen recorder captures your screen. Then Synthesia pairs it with an ai avatar presenter.

The result? A polished how to video that looks like you hired a production company.

This feature is perfect for software demos and step-by-step guides. Businesses use it to create engaging product walkthroughs for their customers.

8. Traducción en un solo clic

This is one of the new features that blew me away.

Click one button. Your entire video gets translated into another language.

The avatar’s lip movements sync to the new language. The voice matches the translation.

Synthesia supports multiple languages — over 140 of them. This means you can reach global teams without creating separate videos from scratch.

For education management and global training, this is a game-changer.

9. Vídeos interactivos

Synthesia lets you create interactive videos with clickable elements.

Add buttons, quizzes, and branching paths. Viewers choose what to watch next.

This is perfect for training videos where different employees need different information.

It also helps enhance engagement. People stay focused when they can interact with personalized content.

Mi experiencia con Synthesia

Esto es lo que realmente sucedió cuando usé Síntesis:

El proyecto: I created an employee onboarding series for a client with remote teams across 4 countries.

Cronología: 60 días de uso activo.

Resultados:

Lo que me sorprendió: The speed was amazing. I finished an entire 8-video onboarding series in two days. Before Synthesia, that would have taken two months and cost over $20,000.

Lo que me frustró: The synchronization between the avatar’s speech and lip movements is sometimes inconsistent. I also wish the ai voices had more emotional range. Some synthesia videos sound a bit flat.

¿Lo volvería a usar? Sí, sin pregunta. For training and internal content, nothing comes close. I just wouldn’t use it for a high-stakes investor presentation where first impressions matter.

Some users have noted that while the quality of Synthesia’s videos is impressive, it’s not suitable for every use case. But for creating videos at scale, it changes your life.

Reflexiones finales

Obtén Synthesia si: You need to create high quality training videos, onboarding content, or how to videos regularly — especially in different languages.

No tomes Synthesia si: You need emotionally engaging marketing content where real actors would perform better.

Mi veredicto: After 60 days of using Synthesia, I’m a believer. It’s not perfect — the avatars still need work on facial movements and emotional range. But for business video creation, nothing else saves this much time and money.

Synthesia is primarily targeted towards business, marketing, and learning and development teams for scalable video content production. If that’s you, this tool deserves a spot in your stack.

Puntuación: 4,6/5
