Ready for lots of screenshots, useful tips and concrete examples? 

Let’s go 👇

Step 1: Gather ideas and define core elements of your video

Before we jump right into creating the content itself, there's some thinking that needs to be done if you want your video to really resonate with the audience. 

Here are some questions to help you get started:

  • What type of video do you want to create? 
  • What should be the key takeaway of your video? 
  • Who is your target audience?

If you already know the answers, you can skip this step.

If not, it’s time to jot down some ideas.

Or better yet, ask ChatGPT to do it for you.

It can help with many pre-production aspects of your video and comes in super handy for brainstorming and idea generation:

  • format of your video
  • sequences
  • characters
  • title ideas… 

Here’s an example of using ChatGPT at the very beginning of the video making process:

ChatGPT can help you brainstorm ideas for various aspects of your video, such as defining characters, suggesting video types, titles, etc.

Step 2: Generate the script with GPT-4

The next step in creating your video is to write the actual script.

You've already defined your audience and the purpose of your video – and it's important to keep this in mind when prompting the AI.

As mentioned before, we'll be using Synthesia for our GPT-4 video, starting with their "Generate with AI" feature to generate your script.

So, how does this actually work (and look)?

These are the key steps of this intuitive process:

  • Log in to Synthesia STUDIO or create an account if you don’t have one already.
  • Click on “Generate script” and fill out the required fields: topic, audience, objective, and tone.
  • You can also regenerate your script and tweak the prompts if you wish.

Once you’re satisfied with the result, it’s time to move to the next steps of your video creation. 

The editor will automatically split your script into different scenes as you can see here:


And now the fun part:

Step 3: Select your AI presenter and voice

Time to choose a presenter for your video! 🗣

This step is super important as presenters (or AI avatars, as we call them) are key to building a human connection with viewers

There are more than 125+ diverse avatars to choose from in Synthesia, representing different age groups, ethnicities, professions, etc.

Add a human touch to your video with an AI presenter. In Synthesia, you can access 125+ AI avatars representing different ethnicities, ages and styles. You can even make them wink, nod, and frown.

But it’s not just the avatar’s look you should choose carefully.

It’s also the avatar’s voice.

Want the tone to be friendly? Professional? Calm? We have them all (in more than 120 languages and accents), and it's up to you to choose the one that best supports your video's message.

So now that you’ve pasted in your script and selected your AI avatar, it’s time to work a little on the visual aspect.

Step 4: Edit the video

Depending on the content of your video, the way you visualize the script will vary. 

You can have the avatar on each scene or leave some scenes without it — it’s up to you.

Here are some ideas that you can use as supporting visuals for your scenes:

  • Charts and diagrams
  • Icons with text
  • Stock or own footage
  • Quotes
  • Screen recording
  • Bullet points...

Step 5: Generate the video

When you’re satisfied with every scene of your video, it’s time for AI to do its magic. 🪄

Click Generate, wait a few minutes, and you’ll receive an email when your video is ready. 

Your options now include downloading (.mp4 format), copying the URL for sharing, or embedding on a desired site.

Make sure you also give it a good title, write an informative description, and share it with your target audience

And that’s it! 👏
