Creating videos isn't a matter of pressing the record button and hoping for the best. It involves scriptwriting, hiring and training actors, investing in studios and equipment, and more. In other words, video creation requires time, money, and energy.

All I did was give it a topic and my target audience. Then, it instantly generated this entirely customizable video, including the script, scenes, and AI actors.

How to Use Synthesia for AI Video Creation

Now that we know everything that Synthesia is capable of let's put these features to use.

Synthesia does not offer a free trial or plan. You can create a free AI video by selecting that option on the homepage, but it's very limited. I went with one of the paid plans to get a complete feel for the software.

Here's how I've used Synthesia to generate an AI video in minutes and how you can, too!

Selecting "Create account" on the Synthesia homepage.

I started by going to the Synthesia homepage and chose “Create account” on the top right.

Choosing the Starter plan for my Synthesia account.

Next, Synthesia asked me which plan I wanted to move forward with. I chose the Starter plan, but feel free to choose whatever plan suits your needs the most, like the Enterprise plan for large companies.

The Synthesia studio.

Once my account was created, I was taken to the Synthesia studio to create an AI video!

Synthesia walked me through how to get started with a brief tutorial. The interface was clean and intuitive, making it easy to navigate its features.

Selecting the "New video" button and selecting "Generate video with AI."

If you want Synthesia to generate an entire video (including the scenes and script), select the back arrow on the top left to get to your Home screen. From there, select “New video” on the top right and “Generate video with AI.”

By selecting “New video,” you can start creating a video from scratch, import a slideshow to convert the slides into the background or choose from one of the 65+ templates.

Generating a video with AI using Synthesia.

When generating a video with AI, you can choose from over 65 video templates to suit the topic of your video or keep the default one if you're unsure. You'll also have to give it a topic.

Optionally, Synthesia will ask you who your target audience is, the language, context, objective, persona, and tone.

Selecting Continue in editor on an AI generated video using Synthesia.

Check out this video I generated on why Synthesia is the #1 AI generator targeted toward educators who want to create professional training videos! I kept it on the default template. Within minutes, I had an entire AI-generated video that looked professional and polished. Talk about a huge time-saver.

I liked this video more, so I selected “Continue in editor” to start editing this video instead of my original one.

Editing the script in the Synthesia video editor.

At the bottom, I could manually edit the script. Overall, I was happy with what Synthesia had generated, so I only made minor tweaks!

Selecting the language button and previewing AI voices when using Synthesia.

I could also choose from over 120 languages and accents in this section by selecting the language button. I previewed some voices by selecting the play button next to them, but I was happy with the default voice Synthesia gave me.

The script editing tools available with Synthesia.

There were also four tools in the center that I could apply by placing my cursor anywhere in the script:

  • Gesture: Add a head nod or eyebrow raise.
  • Marker: Add a marker to animate elements in your video.
  • Pause: Add pauses between words.
  • Diction: Add pronunciations to specific words.

Adding an eyebrow raise gesture to the script in Synthesia.

When adding a gesture, I placed my cursor where I wanted it and selected the type of gesture I wanted to apply. I added an eyebrow raise before “why” in my script.

Adding an animation to text using Synthesia.

Markers are a bit more complicated. Hopefully, this simplifies things:

  1. Add a marker
  2. Select a video element
  3. Click an enter/exit animation
  4. Select the marker from the dropdown menu
  5. Choose the type of animation and adjust the settings

I didn't add animations, as Synthesia automatically applied some to my video.

Adding a pause to the script in Synthesia.

To insert a pause, I placed the cursor where I wanted it in the script and entered the number of seconds.

Changing the pronunciation of a word in the script using Diction in Synthesia.

Diction lets you change the pronunciation of specific words. In this example, I highlighted “Hello” in the script and changed the pronunciation to “hullo.”

I previewed it, and it works well. However, I ended up removing it as I preferred the original pronunciation.

Check out Synthesia's Diction Guide for more pronunciation, phonetic spelling, and abbreviation information.

The scenes in the left panel in the Synthesia editor.

I could look through the scenes in the left panel or add a new one by hitting the “+” at the bottom.

Editing a scene's layout, background color, media, music, and scene transition.

I could save time designing each scene on the right by changing the layout/template, background, background media, music, or transitions.

Additionally, I could upload my own or source images, videos, and music from Shutterstock when adding background media and music. There are sixteen scene transitions, so I had plenty of options to make my video visually appealing and engaging.

Highlighting the Avatar, text, shape, media, and record options at the top of the Synthesia editor.

At the top, I could choose from one of the other 150+ avatars or create a custom avatar. I could add different text types, shapes, and media or make a screen recording!

Changing the text and logo on a Synthesia slide.

You can also make edits directly in the slides. I added more text by double-clicking on the text box, replacing the logo placeholder by selecting it, and adding my own! I found it incredibly easy to make adjustments and move elements around.

Generating an AI video with Synthesia.

Once I was happy with everything, it was time to preview and export.

I previewed my video by hitting the play button in the top right corner. Next, I added a title and description and hit “Generate.”

I appreciated that Synthesia could include captions automatically and that it told me how long it would take to process.

Here is the final result with captions!

Why Synthesia is the #1 AI Video Generator

I was happy that her eyebrows raised near the beginning of the video, where I placed the gesture in the script. I was also impressed by how incredibly natural the AI voice sounded, especially since I barely edited it.

Overall, I'm impressed with how the video came out. Her lips synchronize with the script, and the transitions between scenes seamlessly make the video flow nicely.

Synthesia Alternatives

While is a popular AI video generator, exploring alternative options is essential to find the one that best suits your video creation needs.

Here are some of the best AI video alternatives that I've tried!


Pictory homepage.

Pictory is an AI video generator that aims to streamline the process of creating videos, generate leads, and enhance sales by producing highly shareable video content. The platform has a user-friendly interface, making it easy for beginners and professionals to navigate.

The most apparent difference between and Pictory is that Pictory does not offer AI avatars but relies on stock images and videos for video creation. Synthesia also has millions of pictures and videos you can incorporate into your videos from Shutterstock, but with the addition of AI avatars.

Pictory also only supports English for text-to-video, while Synthesia offers 120+ voices and accents. Pictory also offers far fewer templates than Synthesia (up to 10 on the Teams plan), while Synthesia provides over 65 templates.

Despite both being excellent AI video generators, the uses for both platforms are quite different. Pictory is best for creating video highlights, summarizing long videos, turning scripts into videos, etc. Meanwhile, Synthesia is best for all training videos using AI avatars.

Whichever one you choose, you can be confident that you'll easily create high-quality videos! Synthesia and Pictory offer unique features catering to different video creation needs.

The Synthesys homepage.

Synthesys, another AI video generation platform, lets you create professional AI content at scale using AI voices, humans, and images.

Both Synthesia and Synthesys allow you to create content using AI avatars. However, Synthesia offers over 150 AI avatars to choose from, while Synthesys has over 60 avatars to choose from.

The number of languages to choose from is similar, with Synthesys offering over 140 languages and Synthesia offering over 120 languages and accents. They also have a similar amount of templates: Synthesys has over 50 templates to choose from, while Synthesia has over 65.

The most significant difference between the two platforms is Synthesys has a built-in AI image generator. At the same time, Synthesia offers subtle gestures such as head nods, and eyebrow raises you can apply to your avatar for more lifelike and expressive video creation. You can also generate entire videos (including the script) instantly with Synthesia, which is a huge time-saver.

If you're looking for the platform for the most authentic AI avatar and time-saving features like the AI video generator, go for Synthesia. If you want an excellent AI video generator with additional built-in features like an AI image generator, choose Synthesys!

Deepbrain AI

The Deepbrain AI homepage.

Deepbrain AI specializes in creating AI-generated videos in minutes just by providing a script. With Deepbrain AI, creating AI-generated videos has never been easier.

Synthesia and Deepbrain AI are similar in most ways. Deepbrain offers over 100 AI avatars, while Synthesia offers slightly more, with over 150. Synthesia also has more languages (over 120), while Deepbrain provides over 80 languages. However, you can use both to generate entire AI videos instantly with a script!

The AI avatars on both are some of the most realistic. However, after generating videos from both, Deepbrain's AI avatars look more believable, while Synthesia's AI voices sound more natural.

You can also use Deepbrain AI's avatars for interviewing potential employees, which you cannot do with Synthesia. However, you have more control over how your AI avatar acts with the option to apply gestures like head nods and eyebrow raises.

Regardless of your chosen platform, Deepbrain AI and Synthesia are excellent options for creating AI-generated videos. With their extensive libraries of video templates, support for multiple languages, and advanced editing capabilities, they produce excellent, high-quality results.

Synthesia Review: Is it the #1 AI Video Generator?

The question we've all been waiting for: Does Synthesia live up to its claim of being the best AI video generator?

After testing multiple AI video generators, I can honestly say that Synthesia is among the best AI video generators. It's difficult to definitively say that it's the best overall since that's subjective and dependent on personal opinion and specific circumstances.

I can confidently say in terms of video quality and AI voices, Synthesia is among the best. The templates are also clean and professional, differentiating them from other video generators.

I also prefer the Synthesia interface the most out of any other AI video generator I've tried. It's clean and easy to navigate, and the interface looks good. There's no other way to describe it.

One of the things that sets Synthesia apart from most AI video generators is how quick and easy it is to generate an AI video. Give it a topic and target demographic, and within seconds, you'll have an entire video with all of the scenes, script, and avatars, which you can edit how you want.

Another feature that I've never seen before was the gestures (head nods/eyebrow raises) you could apply to the AI avatars. This added a layer of realism that I'd never seen in any other video generator, and it's incredible how these subtle gestures can make the avatars come alive.

Overall, Synthesia offers a powerful solution for AI-generated videos and is worth considering for those looking to create high-quality training videos and other types of content! You may also want to check out Sora AI, another AI video generator great for content creators, sales teams, and teachers who want to convert text to video instantly.
