Synthesia Review 2024: Features, Pros and Cons

Artificial intelligence (AI) is transforming how businesses create content. One platform leading this revolution is Synthesia – an AI-powered video creation tool.

With Synthesia, anyone can make realistic videos using virtual human avatars. This removes the need for hiring actors or renting equipment.

In this comprehensive review, we’ll explore everything you need to know about Synthesia in 2024.

Let’s begin.

Overview of Synthesia

Synthesia Review

Synthesia utilizes AI to generate human-like avatars that act as presenters in your videos.

The avatars mimic expressions, mannerisms and emotions to seem real. They read out any script you provide with accuracy.

Synthesia makes video production exponentially easier. No film crews or editing skills required.

Quick Verdict on Synthesia

In our tests, Synthesia scores a 4.8/5 overall.

We compared it to similar tools like HeyGen and Visme. Synthesia stood out for its:

  • Ease of use – simple scripting and avatar selection
  • Options – 140+ avatars and 120+ languages

For quickly making professional videos, Synthesia is a top choice today.

Now let’s analyze its key pros and cons.

Synthesia Pros and Cons

Synthesia has many advantages that make video creation almost effortless. But there are some drawbacks too.

Pros of Synthesia ????

Realistic Videos Without Studio Costs:

Traditionally, creating high-quality videos required:

  • Renting filming equipment
  • Hiring actors
  • Renting studio space
  • Professional editing

All this could cost thousands per video!

With Synthesia, the AI avatars act as talent. There’s no need for expensive studios or gear.

You get broadcast-quality results at a fraction of the cost.

140+ Avatars and Counting:

Synthesia offers immense choice for your AI presenter:

  • Various skin tones
  • Unique voices
  • Different ages and genders

With over 140 options today, you can pick an avatar tailored for your audience.

Plus new avatars are continually added.

Simple Video Creation:

You don’t need any prior video or tech skills to use Synthesia. The process is straightforward:

  1. Select an avatar
  2. Enter your script
  3. Download the final video

The AI handles animating the avatars and syncing speech. Even complex product or software demos are easy.

Cons of Synthesia ????

However, Synthesia has some limitations to consider:

Artificial Look On Close Inspection:

The avatars look impressively lifelike at first glance. But on very close inspection, their computer-generated nature shows through:

  • Speech can seem unnaturally perfect at times
  • Facial expressions may not seem entirely human

As AI progresses, realism will keep improving. But for now, it’s not flawless.

Restrictive Personal Plan Limits:

The Starter plan has tight usage caps:

  • Only 120 minutes of video per year which clearly not enough.

For individuals or very small teams, this is restrictive. Upgrading to Enterprise is expensive.

Costly Custom Avatars

Making a custom avatar with your face and voice costs $1000 per year. It’s a premium feature.

For most use cases, the existing avatars should suffice. But the custom option is pricey.

In summary, Synthesia simplifies video production tremendously via AI avatars. But subtleties in their speech and expressions reveal their synthetic origins. And lower tiers have tight limits.

Now let’s examine how we tested Synthesia for this review.

Research Methodology

We thoroughly evaluated Synthesia based on key criteria for ease of use, output quality and capabilities.

Our team tested Synthesia extensively by:

  • Creating over 20 videos with various avatars and languages
  • Evaluating video and audio quality
  • Assessing the platform’s ease of use
  • Comparing output to real human presenters
  • Reviewing advanced features like voice cloning

We measured metrics like:

  • Time to create a video
  • Naturalness of avatars
  • Audio clarity
  • Editing capabilities
  • Customization options

Based on these tests, we gave Synthesia an overall score of 4.8 out of 5.

Benefits of Synthesia for Video Creation

Synthesia makes creating professional videos as easy as writing a script. With its AI-powered avatars, it’s revolutionizing video production. For many use cases, Synthesia can replace the need for:

✔️ Professional actors

You get studio-quality results at a fraction of the cost and time.

Some examples of videos you can make:

  • eLearning: Interactive training modules, how-to lessons

  • HR: Onboarding materials, employee orientations

The applications are vast. Synthesia streamlines video creation for business, education and content creation.

Key Alternatives to Synthesia

  • HeyGen: AI video maker with limited avatar and language support
  • D-ID: Video and image editing via AI avatars
  • Speechify: Text-to-speech video generator with no avatars

For both quality and ease of use, Synthesia scores highest. Next, let’s explore what exactly Synthesia offers.

So your avatar can present videos for global audiences.

The platform accurately reproduces regional accents and dialects. This increases realism and resonance for local viewers.

For example, your avatar can seamlessly switch between:

  • American English

And many more.

Ease of Video Creation

Ease of Video Creation

Synthesia makes video production incredibly simple. Just follow these steps:

  1. Select your avatar
  2. Enter your script
  3. Make minor tweaks like gestures
  4. Download your completed video

The complex AI powering realistic speech, animations and lip sync happens automatically.

You don’t need any technical or editing skills. Synthesia handles the heavy lifting so you can focus on your message.

Custom Avatars

Want an avatar with your own face and voice? Synthesia offers custom models.

The process:

  1. Record a 10-15 minute video of yourself speaking according to guidelines
  2. Submit to Synthesia team for model development
  3. Your customized avatar is created within 10 days

Now an AI-generated version of you can present videos! It mimics your unique:

  • Facial expressions
  • Mouth shapes as you talk
  • Vocal qualities

The cost is $1000 per avatar annually. For most use cases, the ready-made models suffice. But it’s a cool premium option.

Micro Gestures

Subtle gestures make avatars more lifelike. With Synthesia you can add micro movements like:

  • Raising eyebrows
  • Tilting head
  • Rolling eyes
  • Smirking
  • And more

These complement your script with natural motions. Your avatar fidgets, reacts and gestures just like a human presenter would.

Voice Cloning

Want your own voice instead of a text-to-speech model? Synthesia can clone your unique vocal qualities.

To create a voice clone:

  1. Record yourself readingpreset texts.
  2. Submit the recordings to Synthesia.
  3. Your digital voice print is created.

Now your avatar can present videos in a voice indistinguishable from your own. Cloning costs extra, but takes realism up another notch.

How to Create Videos with Synthesia

Let’s walk through how to produce a video with Synthesia step-by-step.

1. Select a Template

Select a template

Synthesia boasts over 200 free templates, giving you a wide range to pick from. Choose one that aligns with your vision, and feel free to tweak it to your liking. If nothing catches your eye, there’s always the option to craft a template from the ground up.

2. Edit the Script:

Edit the script

A script is key, whether for training purposes or explaining a product. Don’t have one? No worries! Synthesia’s AI can generate one for you. Plus, with its multilingual capabilities, you can create videos in your local language.

3. Select an Avatar:

Stick with the template’s avatar or choose another. If you’re inclined towards a more personal touch, opt for a digital twin – an avatar that resembles and sounds like you. This requires a green screen video of yourself and a bit of patience (about 10 days) for creation. If you’re in a hurry, existing avatars are readily available for immediate use.

That’s all there is to it!

Once your video is complete, share it on your website or social media to engage your audience. With Synthesia, creating professional and personalized videos is just a few clicks away!
