You know how much people love video.. And perhaps you also know you should be creating more of it.

Well, now is a great time to get started. 

Thanks to AI video generators, it's easier than ever to create videos from text without any need for camera equipment, actors, microphones, or even video editing skills. 

Not only is this method affordable, it's also scalable, making it a fantastic way to enhance your content creation efforts. 📹

In a few years, 95% of content on the internet will be generated by AI anyway, so why not give it a go before it becomes mainstream?

But what exactly is an AI video generator? 🧐

Good question! Let's define it as a tool that enables you to generate videos from text using AI presenters. While there are many other ways to use AI in video editing, for the purpose of this post, we will be focusing solely on this particular application.

In this blog post, you'll find a detailed overview of the most popular AI video generators on the market: Synthesia, Colossyan, Hour One, D-ID, Elai and Movio.

We’ll have a look into the realism of their AI avatars and voices, we’ll break down different pricing models, list some Pros and Cons, and give an objective conclusion based on these parameters. 

Ready to jump right in?

1. Synthesia

Synthesia is the world’s leading AI video generator that allows you to create videos with AI presenters from text.

It includes more than 55 video templates you can start from, and you can choose between more than 85 AI avatars that can speak your text in more than 120 languages and accents. 🌍

The tool is mainly being used for training videos, how-to videos and product marketing videos.

5 key stand-out features

  1. 120+ voices and accents
  2. 85+ diverse AI avatars
  3. 55+ video templates designed by professional designers
  4. The option to have a custom avatar created
  5. The option to add micro gestures to an avatar (winks, nods…)

Overview of Synthesia's AI avatars

As mentioned before, there are more than 85 stock avatars available in Synthesia and they’re constantly adding more. The selection is broad and diverse, covering different ages, ethnicities, races, and styles.

And yes, Synthesia’s AI avatars look very realistic. The team has just introduced micro gestures, which is currently in beta and allows users to add different gestures to the avatars. To make their communication more human via non-verbal cues, it’s possible to make them wink, nod, frown or raise an eyebrow. 🤨

Synthesia has more than 85 avatars, most of which come in two framings. On the right, you can see two of their avatars performing micro gestures.

Another point worth mentioning regarding AI avatars is the ability to create your own avatar based on video footage of yourself. However, this is an add-on feature and will cost you $1000/year.

Synthesia is constantly working to make avatars even better and is a pioneer in this field with its strong research department and academic background.

Here you can see more about how Synthesia’s AI avatars are made:

How are Synthesia AI avatars created?

Overview of languages and voices

In Synthesia, users can choose from a wide range of voices and accents (more than 400 options), which are constantly being improved. 🗣

For non-users, it’s very convenient that they can listen to all the voices on the website without having to register as a user. It’s also possible to create a clone of your own voice and use it in your videos. This option is supported by Synthesia’s partner Descript.

UX and UI

Synthesia STUDIO works in a browser and is very intuitive to use. 

In STUDIO, you can easily access templates, avatars, voices, stock footage, and it also allows you to upload your own brand assets. You can easily organize your projects using folders. 📁

The updated Synthesia STUDIO app's UI
Synthesia is the world’s leading AI video generator. It allows you to easily create videos from a browser in more than 120 languages.

What’s missing in Synthesia STUDIO is the collaboration aspect that would allow teams to work on projects together (like for example in Figma, Canva or Miro). According to the company's information on social media, this option is soon to be released.

Pricing breakdown

Synthesia offers users two paid plans:

➡️ Free demo: available on their website

➡️ Personal plan: $30/month for 10 minutes of video

➡️ Corporate plan: individual pricing for different users

To be honest, the personal plan is only sufficient for small users. It also has some limitations, such as 6 scenes per video. It’s an affordable way to get to know the technology and test it out, but for more demanding users it may not be enough.

Social proof

Synthesia is being used by 20.000 companies of all sizes, with many big logos among them, such as Reuters, Teleperformance, Amazon, and BBC.

They have an extensive library of case studies where you can see real examples of how and why companies large and small are using Synthesia to generate videos, with some concrete money and time savings.

The software currently has 394 reviews on G2 and has a rating of 4.8 out of 5, which makes it the category leader.

Synthesia has helped me to create YouTube channels offering video information about articles and guides I have in my projects. The operation is very simple and the creation is very fast. Creating different avatars in other languages has allowed me to make channels for my websites in English, Spanish and Portuguese. It's amazing, before Synthesia I never thought of having this. I recommend this application 100%. Arturo V.

Pros 👍

There are many reasons why you should give Synthesia a try:

And there are other reasons than the product itself:

  • The company is the pioneer in the field of AI video.
  • The company has an excellent knowledge base and regularly hosts webinars.
  • The company has a professional moderation team and follows the highest security standards.
  • They have a lively community of more than 2000 users on Facebook.

Cons 👎

  • No collaboration options yet
  • No resize option yet (1920×1080 pixels only)
  • The pricing plans could be more flexible

Conclusion

If you're looking for state-of-the-art AI video generation software, Synthesia is the right solution for you. Besides the realism of the avatars, you can start creating your video right away, since the interface is very intuitive. 

Their strong thought leadership, the highest security and ethical standards, and R&D culture show that the company is a true leader in the AI video space that you should definitely keep an eye on in the coming months.

2. Colossyan

Colossyan is an AI video generator that lets you create videos from text and add AI actors. The main use cases are learning and training videos, explainer videos, corporate communications, and marketing.

Here’s how it works:

Create AI videos with Colossyan

6 key stand-out features

  1. 70+ languages
  2. 30+ AI actors
  3. Multiple actors in one scene
  4. The option to adjust emotions and age of each AI actor 
  5. The option to resize your video to different aspect ratios
  6. The option to have a custom avatar created

Overview of Colossyan's AI avatars

Colossyan offers around 30 AI avatars to choose from, and you can also create your own, custom avatar for $1000/year. 

One feature that stands out is the ability to set the age and the emotions of each avatar with a single click. However, this is only available to enterprise clients.

Overview of languages and voices

In Colossyan, you can choose between more than 70 voices and accents. 🗣

The tool also allows for automated video translation between 26 selected languages, but we haven't tested the accuracy of these translations.

An overview of languages and voices on Colossyan
Colossyan supports more than 70 languages.

UX and UI

Colossyan Creator is fairly easy to use and navigate. The only thing that feels slightly counterintuitive is the script box being placed on the left side of the video, but that shouldn’t be too much of an obstacle. 

An overview of Colossyan Creator app
Colossyan AI video generation software is minimalist and easy to navigate. One feature we like is their voice selection menu.

Pricing breakdown

Colossyan offers three paid plans to their users:

➡️ Free demo: 5 minutes of video (with watermark)

➡️ Basic plan: from $21/month for 10 minutes of video

➡️ Pro plan: from $100/month for 40 minutes of video

➡️ Enterprise plan: custom prices

Each of these plans, of course, has some limitations and only the enterprise plan has all the features available. 

In summary, Colossyan’s plans may seem slightly complicated, but are very flexible and accessible to a wide range of users.

Social proof

We couldn’t find the information about the number of customers using Colossyan. 

On G2, it has 28 reviews, which are mostly positive:

So far it's features and intuitive nature of the UX, I was able to quickly and easily create my first video as a paid client. Also, the speed of creation was acceptable. G2 review

Pros 👍

  • Automated video translation
  • Multiple aspect ratios for your videos
  • Easy to use
  • Different pricing plans to choose from

Cons 👎

  • Lip syncing is a bit off, feels uncanny
  • Lack of diverse avatars
  • Lack of social proof with only 28 reviews on G2

Conclusion

Colossyan definitely is one of the best AI video generators on the market. They offer some really useful features (automated translations, multiple aspect ratios) and are constantly adding more.

Their avatars do not have the quality of Synthesia’s avatars. Still, their different pricing plans may make the tool more attractive to some. They also have a community of 300 members on Discord.

3. Hour One

Another AI video generator specializing in virtual humans in video is Hour One. Reals, their self-service video editing platform, makes it easy to create engaging videos from text in minutes. 

Here’s how it works:

Create AI videos with HourOne

4 key stand-out features

  1. 30+ AI characters
  2. 27 video templates
  3. 19 languages
  4. Brand kit option that allows you to define your brand color palette

Overview of Hour One's AI avatars

The tool includes more than 30 AI presenters that can narrate your video. They are based on real people, but look and act a bit robotic when used as AI avatars.

An overview of Hour One's AI avatars
There’s a wide range of AI avatars you can use as presenters in your videos.

Overview of languages and voices

With Hour One, you can create videos in 19 languages, and each of them has some voice and tone variants you can choose from.

One can only listen to the voices and accents in the editor, where they are named with personal names, which we don't find very informative and descriptive.

An overview of Hour One's languages and voices
In Reals you will find many AI voices in 19 different languages.

UX and UI

The interface of Reals is minimalistic, yet easy to navigate. The script box takes up most of the space, and we wish the visual part of the video was more prominent.

But as the platform doesn’t offer that much video editing capabilities, it makes sense it’s more focused on the script part. 

Hour One's Reals interface
Reals, the AI video generator by HourOne is easy to navigate, but we miss more flexibility when editing different scenes.

Pricing breakdown

Hour One offers its users three paid plans:

➡️ Free demo: 3 minutes of video

➡️ Lite plan: from $30/month for 10 minutes of video

➡️ Business plan: from $229/month for up to 20 minutes of video

➡️ Enterprise plan: custom pricing for industrial-grade AI video production

What we like about the pricing is that you can pay extra for additional minutes of video generated:  $5/minute on the Lite plan and $15/minute on the Business plan. The other AI video generators mentioned in this article do not allow you to simply buy extra minutes.

Social proof

Hour One is not on G2, so we couldn’t find any possible independent reviews. However, some big logos are using the tool for their video creation: Berlitz, DreamWorks, NBC Universal, to name a few.

Pros 👍

  • It allows you to define your brand colors for better consistency
  • Tiered and affordable pricing plans
  • The option to buy extra minutes if needed
  • The option to generate images from text within the editor

Cons 👎

  • Not possible to change fonts
  • The editor is a bit slow and glitchy from time to time
  • AI avatars don’t seem lifelike, their realism is not there yet

Conclusion

Having put the tool under the microscope, we can say that Hour One is a robust and affordable AI video generator.

But regardless of the fact that some big logos use it, it doesn't make us feel like we could trust it 100%. Also, the realism of the AI avatars is far from the AI avatars available in Synthesia, for example.

4. D-ID

Another name that comes up when discussing best AI video generators you may consider to create videos with AI is D-ID. 

While all the already mentioned platforms (Synthesia, Colossyan, Hour One) focus on text-to-video generation using AI avatars, D-ID also allows you to create videos from still images of faces.

Recently, Creative Reality™ Studio was introduced, a platform that combines several generative AI applications:

  • text generation with GPT-3
  • text-to-image generation with Stable Diffusion
  • their own face animation AI technology

See more about it in this short video:

D-ID Avatars

3 key stand-out features

  1. Live portrait feature that allows you to get a talking head video from still images
  2. AI text-to-image generation within the tool 
  3. AI script generation within the tool

Overview of the AI avatars

When it comes to AI avatars, you have 3 options:

1️⃣ Lifelike AI avatars: There are 29 presenters available in the video editor, 4 of which are marked as “high quality.” These look like real people when static, but their animated appearance in video clips still feels pretty much uncanny.

2️⃣ AI avatar from a still image: You can upload a frontal-facing still image, and the tool will turn it into an AI avatar speaking out the words you want them to speak.

3️⃣ Cartoonish AI avatars: These avatars are fully generated by AI, and you can also generate new avatars based on your text prompts. 

We believe that realism is not the primary goal when it comes to cartoony avatars, but it can be said that it is also lacking when using D-ID’s lifelike characters. 

Overview of D-ID's AI avatars
D-ID offers many options for selecting your AI avatar. You can create one from a still portrait, generate one using AI, or use one of their AI avatars.

Overview of languages and voices

There are 119 languages and accents you can choose from. We especially like that after selecting the voice, you can further define its style (shouting, whispering, sad, excited…) to make it even more expressive.

It’s also possible to upload your own audio file.

An overview of D-ID's languages and voices
This is how selecting a voice looks like in D-ID’s video editor.

UX and UI

The interface of D-ID is easy to navigate, but we did miss some more video editing capabilities.

Overview of D-ID's interface and UX

Pricing breakdown

D-ID offers three paid plans to their users:

➡️ Free demo: 5 minutes of video

➡️ Lite plan: from $5.99/month for 10 minutes of video

➡️ Business plan: from $49.99/month for up to 15 minutes of video

➡️ Enterprise plan: custom prices and plans

The plans come with different limitations, especially when it comes to presenters available and watermarks.

Social proof

There’s been some buzz around D-ID in the media lately. However, we miss some more social proof and user reviews when browsing the internet (only 1 review on G2).

Pros 👍

  • All-in-one generative AI tool
  • The ability to generate videos from still images
  • Many creative use cases using cartoonish AI avatars

Cons 👎

  • Lack of avatar realism
  • Lack of video editing capabilities
  • No resize option

Conclusion

The biggest breakthrough of D-ID is its recently launched multimodal AI video creation platform that combines text, image, and video generation using AI.

While this opens up many possibilities for creative expression, D- ID 's AI avatars lack human realism. Our prediction is they’re going to focus more on the creative aspect of combining different media formats rather than traversing the uncanny valley of their lifelike avatars.

5. Elai

Elai.io is another text-to-video platform that allows you to make videos with AI presenters from your browser. It was founded in 2021 and is a relatively new player in this space. 

So let’s take a closer look at how it works and how it differs from the other AI video generators mentioned in this article.Here’s a quick video product tour:

Elai

4 key stand-out features

  1. 65+ languages
  2. 25+ avatars available
  3. Different aspect ratios for videos
  4. Different types of avatars

Overview of Elai's AI avatars

There are 25+ realistic AI avatars to choose from when making videos with Elai. 

However, what really stands out is the option to have your own avatar created – which you can do in 4 different ways:

1️⃣ Selfie avatar (based on footage you can film with a smartphone or webcam)
2️⃣ Studio avatar (based on high-quality studio footage)
3️⃣ Photo avatar (based on a photo)
4️⃣ Animated mascot (based on an illustration of a mascot)

Note that these are all add-on options, and the less effort it requires, the more uncanny it will look in your video.

Overview of Elai's AI avatars
In Elai, you can filter avatars by outfit/occupation. It also offers 4 different types of custom avatars.

Overview of languages and voices

The tool allows you to create videos in more than 65 languages. There is a descriptive list of languages available on their website, but unfortunately it’s not possible to listen to them before using them in a video.

Overview of Elai's languages and voices
There are 65 languages available, and you can find the right one using a search bar.

UX and UI

The in-browser video generation platform is easy to navigate.

We especially like some filtering options that make creating videos even easier.

An overview of Elai's app interface
The tool is easy to navigate and offers many different horizontal, square and vertical templates.

Pricing breakdown

Elai.io offers three paid plans to their users:

➡️ Free demo: 1 minute of video

➡️ Basic plan: from $29/month for 15 minutes of video

➡️ Advanced plan: from $99/month for 15 minutes of video

➡️ Corporate plan: custom prices

The pricing plans allow for a lot of flexibility, so users can easily choose the one that works best for them.

Social proof

Since the company is new to the market, it’s understandable it doesn’t have much social proof yet. They have 1 case study on their website, a few hundred followers on LinkedIn, and only 2 reviews on G2.

There can be some issues when rendering videos though, but this is nothing compared to the huge benefits of the service. I believe that all the minor problems will be solved in the near future, and this platform will become even more perfect! G2 review

Pros 👍

  • Multiple aspect ratios available
  • Pre-designed templates in different aspect ratios
  • Unlimited number of slides

Cons 👎

  • Lip syncing feels uncanny
  • Lack of social proof
  • The editor is slow

Conclusion

Elai delivers what it promises. It’s an easy way to create AI videos, and a very accessible one too.

The convenience of creating a custom AI avatar based on an image or smartphone-quality footage can be very appealing, but it’s not the best solution if you’re looking for high-quality lip syncing and realistic avatar performance.

6. Movio

Movio was founded in 2020 and is another hot AI video generator. It’s great for anyone who wants to create engaging and professional videos for marketing, sales, training, and learning.

It works in 20 languages, includes more than 80 AI presenters and some other interesting features:

Movio

5 key stand-out features

  1. 80+ AI avatars
  2. 36 templates
  3. 20 languages
  4. Face-swap option within the platform
  5. Landscape and portrait format for your videos

Overview of the AI avatars

In Movio you can choose between 80+ stock avatars. Some of them are modelled after real people, and others are entirely computer generated. 

Most of their AI avatars come in different outfits (up to 5 different outfits per avatar), which can be useful when using a specific avatar as one of your brand representatives/assets. 

You can also make your own custom avatar in 4 different ways:

1️⃣ TalkingPhoto option: upload a photo and bring it to life 

2️⃣ Avatar Lite option: get a custom avatar with no professional setup required

3️⃣ Avatar Pro option: get a high-quality avatar based on a 2-minute shot

4️⃣ CG avatar: get a human-like 3D avatar to act as a mascot

Another unique option that Movio offers is the face swap feature in their editor.

You simply upload your photo and swap your face onto an existing AI avatar. 🎭

An overview of Movio's AI avatars
3 different ways to create your avatar in Movio.

Overview of languages and voices

There are 20 languages supported and more than 200 voices available. You can give them a listen on the website.

We like that when in the editor, you can further tweak the voices using a special feature.

Overview of Movio's languages and voices
Choosing the voice you want is easy, and you can also set the speed of the selected voice.

UX and UI

The video editor is easy to navigate and the video creation process is simple. There are some filtering options that even speed up the process. 

Unlike other AI video generators we mention in this article, Movio’s video editor works with a timeline. So instead of slides and scenes, here you have a timeline with different elements that appear in your video.

Overview of Movio's interface
In Movio, you edit your videos using the built-in timeline. 

Pricing breakdown

Movio offers three paid plans to their users:

➡️ Free demo: 1 minute of video

➡️ Essential plan: from $30/month for 10 minutes of video

➡️ Pro plan: from $225/month for 90 minutes of video

➡️ Enterprise plan: custom prices

With this flexible pricing, users can easily choose the option that works best for them.

Social proof

When looking for social proof, we couldn’t find much of it. What we miss are some logos using the tech, and also some real user stories. 

However, we were surprised at how lively their communities are. Their Facebook community has 9000 members, and there are 1141 active members on their Discord server. 

On G2, they currently have 43 mostly positive reviews. Here’s one of them:

It's exactly what I was looking for! Very easy to use, and simple and it has a whole of exciting options: the type of persons, the match with the voices, and the dashboard it's too simple to use.

Pros 👍

  • Referral scheme
  • Big and active community on Facebook and Discord
  • The option to change the speed of a selected voice

Cons 👎

  • Realism is not there yet
  • No actual case studies proving business value of the tool
  • Video templates only contain 1 slide

Conclusion

At the moment, Movio may not yet be the most advanced tool in its class, especially regarding avatar realism.

But as with the other tools presented in this article, we believe it has great potential for further development in the future.

And the winner is...

So that would be our honest overview of the most popular AI video generators at the moment.

As you can see, there are quite some nuances to them.

While some focus on the realism of AI avatars, others tend towards less lifelike presenters. Some employ professional content moderators, while others are less strict when it comes to moderation. Some focus on narrow use cases, while others focus on a wide range of more creative uses of AI video.

The choice, of course, is yours. There are many factors to consider and it all depends on your needs.

However, if we had to name the best one, it would definitely be Synthesia

It has the best quality of AI avatars, video editing capabilities, and a clear standpoint on where they position themselves as a company within the ever-evolving AI space. 

Let’s say we’ve done our job with testing the best AI video generators – and now it’s your turn. 😉
