How to create AI videos using Synthesia

Create an AI Video in 4 Minutes with Synthesia ⚡️

You can create an AI video in 5 simple steps with Synthesia:

Step 1: Create a new video

Step 2: Paste in your script

Step 3: Choose an AI avatar

Step 4: Edit your video

Step 5: Generate your video

Let's get started!

Step 1: Create a new video

Log in to Synthesia, then click 'New video'. You can start from blank or choose one of a wide variety of templates. I recommend you choose a template for the best results. You can customise everything later.

Tip 💡

Speed up the design process by using a video template

If you don't have an eye for design, or you simply want to save even more time, use professionally-designed video templates.

Synthesia has 55+ video templates for a wide range of video types, from training videos, marketing videos, explainer videos, promo videos, video presentations, and so much more.

And, you can still adjust every element to your liking!

After selecting a template you can click the ‘Add scene’ button on the left to see the various layout options that come with your chosen template. You can use these scenes to start to build out the structure of your video.

Step 2: Paste in your script

‎Synthesia's is an AI video generator based on a text-to-video model - which means that you can create videos just by typing text.

One option is to just upload a document: Synthesia can handle PDF documents, PowerPoint files, Word documents, and TXT files.

However, for the best results I recommend you review your text and transform it into a video script. It's not as difficult as it may seem, but it makes a world of difference to the video creation process. We have a dedicated guide to creating video scripts to help you out.

Once you have that ready, copy your video script and paste it into the script box scene by scene. Synthesia will use that text to generate a text-to-speech voiceover for your avatar.

Your avatar can speak in more than 140 languages. You can either type your script in your target language, or type it in another language and translate it later.

The text-to-speech we use is pretty damn good, but if you find that it's mispronouncing words, you can always adjust the pronunciation and add pauses and emphasis to improve the narration.

‎Step 3: Choose an AI avatar

This is where the AI comes in to perform its magic.

In this step, you can choose an AI avatar to act as a narrator/presenter in your video.

There are 230+ diverse AI avatars to choose from, and you can choose where you want the avatar to appear, how large or small it should be or hide it altogether.

To add an AI avatar in Synthesia, click 'Avatar' in the panel on top of the video canvas.

Pick the avatar(s) you want to use and the framing (Full-body, Circle, Voice only). Adjust the position and size of the avatar on the video slide by left-clicking on it with your mouse.

Step 4: Edit the video

It's time for video editing. Luckily, you won't need any fancy video editing software for this.

Here are some of the things you can add and change in your AI video without using external video editing tools:

  • Images (stock or own)
  • Backgrounds videos
  • Screen recordings
  • Background music
  • Shapes
  • Text on screen
  • Animations, transitions
  • GIFs, icons, logos

Step 5: Generate the video

That's it; you've just made an engaging video using AI.

Once you press 'Generate video,' Synthesia will perform some AI abracadabra and, well, generate the video.

Once the video passes through our content moderation process, you can view it, share it, download it, or embed it.

And if you really like it, you can even duplicate it or create a video template from it.
