How to create a YouTube video with ChatGPT and Synthesia

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-3

The next step in creating a video with GPT-3 is writing the actual script

You’ve outlined your video and defined your audience — and this is something to keep in mind when prompting GPT-3.

💡Good to know

Just a heads up, ChatGPT's maximum response length is around 500 words, which is roughly equivalent to 3 minutes of video content. Now, if you need a longer response, the best way to do that is by writing different sections of the script separately.

ChatGPT can help you write both the narration and the dialogs.

Here are two examples:

When it comes to writing the script, you can ask ChatGPT different questions. You can prompt it to write a dialog, a narration, or any other text you want for your video.

Step 3: Go to Synthesia (or any other AI video generator)

Let’s suppose you have your script written, so now it’s time to "translate" it into video. 

As mentioned at the beginning, we’ll be using Synthesia - you can create your Synthesia account here.

After you have logged in, you have two options:

1. You can start creating your video from scratch.

2. You can start creating your video from a template.

Both have pluses and minuses; if you’re in a hurry, we recommend using templates, and if you want to play around with the tool, you should start with a blank canvas.

📹 Save time using templates!

Using Synthesia, you can choose between 55+ video templates for different use cases (marketing, training, sales, reports, how-to...). You can find all templates here →

Step 4: Copy and paste your script 

Next step: copy and paste the script from ChatGPT ⏩ into ⏩ Synthesia.

Depending on the structure of your script, you will create your video based on scenes. 

Each of these scenes should be slightly different in order to keep your viewers engaged. 

Now insert the script from ChatGPT (or wherever you have the text) into specific scenes of your video.

Step 5: 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 85 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 85+ 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.

Here’s 3 tips for choosing the right avatar and voice:

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 6: 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...
💡 Good to know

In Synthesia, you get instant access to millions of stock videos, images, and icons. You can further customize your video using different fonts, colors, shapes, music etc. It also allows you to upload your own branded assets. Check out some videos made entirely with Synthesia →

Step 7: 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! 👏
