Synthesia AI review: What Is Synthesia?

synthesia ai video generator

The Synthesia AI video creator was founded in 2017 by high-level researchers and entrepreneurs from UCL, TUM, Stanford, Foundry, and Cambridge. This game-changing synthetic media software is an AI video generator that creates videos from text prompts. 

Synthesia is already a global leader in synthetic media and works with some of the world’s most notable media brands, such as British Broadcasting Corporation (BBC), McDonald’s, Reuters, Accenture, WPP, and Ernst & Young.

You can use Synthesia to create engaging videos for e-learning, customer onboarding, YouTube channels, websites, advertisements, and other marketing materials. With this AI video generator, you don’t need a studio, actors, video recording, or audio equipment to make a high-quality video.

How Does Synthesia AI Work?

Creating a video with Synthesia is simple. All you need to do is follow a few steps, and the tool does the rest. Here’s a step-by-step guide to creating a video with Synthesia:

1. Choose a Suitable Presenter or Create Your Own

In the Synthesia panel, you’ll find more than 40 presenters to choose from. If you’re on a premium plan, you can also create and customize your own avatar. After choosing or creating the avatar, you can change the following aspects: 

  • Background
  • Images
  • Music
  • Shapes

2. Write Down a Script

You’ll need to write a script for your video before beginning the video creation process. You also have the option of uploading a video you currently have in your library so that Synthesia can create a duplicate video in a different language. Simply choose the target language, accent, and voice, and Synthesia will generate the video for you in minutes.

3. Let Synthesia Process the Script and Create a Video

If you’re creating a video from scratch, the AI tool will rely on your script as the basis for your video. After writing the script and selecting your preferred language, the AI tool will begin generating the video. 

4. Download and Stream the Video

This is usually the last step after Synthesia completes processing your video. Once it’s ready, you’ll be prompted to save, stream or share your video.

Popular Use Cases of Synthesia

You can use your Synthesia-created videos for just about anything, but here are some of the most popular uses: 

  • E-commerce videos
  • Tutorials
  • How-to videos
  • E-learning
  • Corporate communications
  • Visual chatbots

Key Features

Here are some of the most notable features of the Synthesia video creator:

Converts Text Into Video in Minutes

The Synthesia AI video generator tool transforms plain text into a professional video within minutes. It can create a high-quality video up to 30 minutes long. 

Customized Avatars

If you don’t wish to use one of the built-in presenters, you can create your own deepfake avatar. Creating a customized avatar only takes about five minutes. 

To do this, upload an image of yourself, then let the AI tool generate an avatar for you. 

Note that this avatar creation feature is not free. This add-on costs around $1,000.

  • Shoot your own video.
  • Submit the video to Synthesia.
  • Pay for the add-on feature.
  • Wait for the processing, which can take up to 10 days.
  • Access the avatar in your Synthesia studio application.

Note that to prevent abuse of the system, Synthesia requires consent from anyone planning to create a custom avatar. You’ll need to record a video and read out a consent script provided by Synthesia. Then, you’ll upload it as part of your footage.

  • Creates videos in over 40 languages
  • Exports videos to user’s Learning Management System

Synthesia Cons

Synthesia AI Pricing

synthesia ai video creator

Synthesia has a free trial, which is limited to 200 words for the first video. On the free trial, you can select a video style, write a script, and then let Synthesia create the video. 

You’ll also need to provide an email address to receive a link to the video, which will arrive in about two minutes after video processing. 

After your free trial, Synthesia has two paid plans: Personal and Corporate. 

Personal Plan

The Personal plan costs $30 per month. Some of its features include: 

  • Text to video support
  • 10 video credits each month (each credit is equivalent to 1 minute of video)
  • Up to 50 different languages
  • MP4 downloads
  • Pre-built templates
  • Video sharing pages

Limitations of the Personal Plan

While the personal plan might be a great fit, it does come with some limitations, as explained below. 

Limited Monthly Credits

If you use up your allocated monthly credits, you’ll need to buy 10 extra credits for $30. That means you can’t exceed a cumulative video length of 10 minutes per month unless you spend more money.

Limited Video Length

The Personal plan is limited to a video length of 10 minutes, no matter the number of credits. This means that if you want to create longer videos, you’ll need to upgrade to the Corporate plan.

Limited Amount of the Number of Videos You Can Merge

The number of videos you can merge into a single video is limited to six. For this reason, you’ll need to plan accordingly on how you’ll use the multi-slide feature.   

Paid Advertising Campaigns Restrictions

Synthesia prohibits using its videos with built-in avatars in social media paid advertising campaigns, such as Facebook or Instagram ads. But you can still embed the videos on your website or post them on your social media page as long as you don’t promote them. 

If you want to use Synthesia-made videos with built-in avatars in paid advertising, you’ll need to upgrade to the Corporate plan or buy the custom avatar feature for $1,000.

Lack of Custom Avatars

A personal plan user will need to upgrade to the corporate plan to access custom avatars. 

Lacks API Access

You’ll need to upgrade to the Corporate plan if you want to use the Synthesia API to create custom videos with a few lines of code.

Corporate Plan

The Corporate plan pricing depends on your needs and use cases. For the exact pricing, users are required to contact support.

Synthesia’s Corporate plan includes: 

  • All personal plan features
  • Up to 50 slides for a single video
  • Audio uploads
  • Custom fonts and avatars
  • API access
  • Priority support
  • Access to premium services

You can request a demo to try out the Corporate plan before purchasing it. To do this, visit’s website pricing page and click on Book a Demo. After that, fill in and submit your personal information in the contact form that appears. 

Users who want to create short videos or promos would likely do better on the Personal plan. However, if you want advanced features such as API access and long-length videos, the Corporate plan is probably a better option.
