Synthesia is an AI video creation platform that lets you make videos without needing cameras or microphones. Instead, you type your script, and an AI avatar speaks it. This is like having digital actors ready to deliver your script perfectly every time, without needing a coffee break.

AI Avatars

There's a good variety, and you have some customization options. Avatars serve as the visual presenters of your content.

AI Voices

These come in many languages and styles, making your videos accessible to diverse audiences around the world.

Listen to Voices

Video Templates

These help you start quickly with a professional design. Synthesia's templates are like pre-built stage sets; you just add your avatars and script, and the scene is ready.

Common uses for Synthesia include training videos, marketing content, and presentations. I've seen it used for many how-to guides too. Synthesia offers different plans with a free trial that has some limits, but paid plans unlock more features. For our 15-minute goal, even basic access works fine.

To follow this tutorial smoothly, here's what you'll need:

Stable Internet Connection: Synthesia is a web-based tool so good internet is essential.
Modern Web Browser: Chrome is often recommended for best performance, but Firefox or Edge work too.
Synthesia Account: You can sign up for a free trial or use a paid account. You can usually find a sign-up link on their main website.
A Simple Script Idea: Just a few sentences are enough to get you started.
(Optional but Recommended): A quiet environment helps you focus.

Understanding these basic terms will help you tremendously. These are words you'll see in Synthesia and in my tutorial:

Term	Definition
Avatar	This is the AI presenter in your video, the digital person who speaks your script.
Scene	Think of a scene as one segment of your video. It's similar to a slide in a presentation.
Script Box	This is the area where you type or paste the text for the avatar to speak.
Voiceover	This refers to the AI-generated narration of your script.
Template	A pre-designed video layout. Using a template really speeds up creation.
Canvas	This is the main editing area where you see a preview of your video as you build it.

First up, let's get you into Synthesia. If you already have an account, you can just log in. If not, signing up is simple.

Signing Up/Logging In:

Go to the official Synthesia website.
Look for a button like “Get started for free” or “Login.” Click it.
If you're new, follow the instructions on screen to create your account. Otherwise, just enter your login details. I found the process quite quick.

Dashboard Overview:

Once you're in, you'll see the main dashboard. It's your command center. You should spot sections like Templates, Avatars, and My Videos. The Create Video button is usually prominent. Take a moment to find where your account settings or profile information is located. It's good to know for later. Also, look for a “Help” or “Support” section. Synthesia typically offers resources if you get stuck. My experience shows these are quite useful.

Now, go ahead and log in to your Synthesia account. Try to locate the ‘Create Video' button and the ‘Templates' section. This way, you'll be ready for the next step.

Create Synthesia Account

Alright, with your account ready, let's start making a video. Using a template is the fastest way, especially for your first one.

Click Create Video

Navigate to Templates

Browse Options

Preview Templates

Select Template

Click that Create Video button you found earlier on the dashboard.
This action usually takes you to where you can choose how to start. Navigate to the Templates library. I always recommend starting here for speed.
You can browse the templates or use filters. Synthesia often has filters for categories like “Training,” “Marketing,” or “Presentation.” This helps narrow down choices. Sometimes a keyword search is available too.
To see what a template looks like, you can usually hover your mouse over it or click it for a preview. This gives you a quick idea of the style.
Once you find one you like, click “Use this template” or a similar button. My testing shows this loads the template into the editor.

Pro Tip: While you can start with a blank canvas for more control, focusing on templates keeps us within our 15-minute goal. For now, browse the Synthesia template library. Select a template that looks good or seems relevant for a simple test message.

Browse Synthesia Templates

Now that you have a template, it's time to choose your AI presenter and their voice. This step personalizes your video.

Accessing Avatar Selection:

Inside the video editor with your template loaded, you should see a placeholder for the avatar. Or, there might be an avatar selection panel. This is where you make your choice.

Choosing an Avatar:

Browse through the library of stock avatars. Synthesia offers a range of looks and styles.
Simply click on an avatar to select it for your current scene. I find it's best to pick one that fits the tone of your message.

Avatar Positioning & Framing (Basic):

You can often choose how the avatar appears. Look for options like full body, a circular frame, or even voice-only if that fits your needs and saves time.

Voice Configuration:

Find the voice settings panel. This is usually near the avatar or script area.
Language Selection: First, choose the language you want your avatar to speak. My experience shows Synthesia supports many languages.
Voice Selection: Next, browse and preview the different AI voices available for that language. Listen to a few to find one you like.
Some voices might have style adjustments like “Newscast” or “Conversational.” If these are easy to access, feel free to try one. But for speed, the default often works well.

Best Practice: Go on, select an avatar for your chosen template. Then, pick a language and a voice. Don't forget to preview the voice to make sure you're happy with it. Testing the voice before proceeding will save you from having to regenerate your video later.

Explore AI Avatars

With your avatar and voice set, it's time to give them something to say. This is where you add your script.

Locating the Script Box:

You'll find a script input area or script box clearly visible in the editor. This is usually linked to the scene you are working on.

Adding Your Script:

You can type your script directly into this box or paste it from another document.
For your first video under 15 minutes, keep the script short and to the point. I suggest 2-3 sentences per scene. This is a key tip for speed.

Using the AI Script Assistant (if aiming for extreme speed):

Some AI video tools offer a script assistant. Synthesia might have one. The AI script assistant is like having a co-writer who can quickly sketch out ideas or polish your lines, speeding up the brainstorming process. If it's there and seems quick, it might help refine short script snippets.

Text-to-Speech Timing & Pauses (Basic):

Synthesia's AI is pretty good at handling timing automatically. You can add simple pauses using punctuation like commas and periods. For more distinct pauses, some tools allow commands like <break time="1s">, but check Synthesia's guide for specifics if you need this.

Previewing Audio:

Look for a “Listen” or audio preview button. This lets you hear how the current scene's script sounds with the AI voice. I always use this to check pronunciation.

Managing Scenes (Very Basic for first video):

If your template has several scenes, you'll see a way to navigate between them, perhaps as thumbnails on the side. For this quick tutorial, focus on editing the script for just one or two scenes.

Quick Task: Now, in the first scene of your template, type or paste a short, two-sentence script. Then, listen to the AI voice narrate it. This will give you a feel for the process.

Try AI Script Generator

You're almost there! The final steps involve previewing your work, letting Synthesia generate the video, and then getting it out.

Previewing the Full Video (Draft):

Before generating, look for a “Preview” or “Play All Scenes” button. This often shows a quick, low-resolution preview of your entire video. It's great for a final check of flow and script.

Initiating Video Generation:

When you're ready, click the “Generate Video” button. Synthesia will usually ask you to give your video a title at this stage.
Be aware that video generation takes a little time. Synthesia will process it and should notify you when it's done.

Understanding Generation Time:

It's not instant. The length and complexity of your video affect how long it takes. For the short video we're making in this tutorial (likely under a minute), it should be fairly quick. I've seen short ones process in just a few minutes.

Accessing Your Generated Video:

Once generated, you'll find your video in a section like “My Videos” or through a notification link.

Basic Export/Sharing Options:

After your video is ready, look for a download button. This typically gives you an MP4 file. Sharing links might also be available directly. For a first video, the default resolution is usually fine.

Final Action: Time to try it: Generate your short video. Once it's ready, download the MP4 file to your computer.

Generate & Export Your Video

Congratulations! You've successfully created your very first AI avatar video using Synthesia in under 15 minutes. That's a fantastic achievement.

You've quickly learned the core steps: Account Setup, choosing a Template, configuring your Avatar and Voice, adding your Script, and finally, Generating your video. Now, take a moment to re-watch your creation or perhaps share it with someone. Well done!

Create Your Next AI Video

You've now mastered the fundamental process of creating a quick video with Synthesia. That's excellent! The following tips are for when you want to build upon these foundational skills. They can help you refine your workflow, making future videos even quicker or improving their quality.

Using a few shortcuts can make a big difference. Here are some ideas that generally speed things up in tools like Synthesia:

Keyboard Shortcuts

Many web applications have keyboard shortcuts. Look for ones like Ctrl+S (or Cmd+S) to save your script, or shortcuts to play/pause scene audio. Synthesia's help documentation might list these.

Duplicating Scenes

If you need similar scenes, don't rebuild them from scratch. Duplicate an existing scene and then just modify what's different. I find this saves a lot of time.

Reusing Avatars/Voice Settings

Once you find an avatar and voice combination you like, see if there's an easy way to apply these settings across multiple scenes or save them as a default.

Batch Script Upload

For slightly longer videos, some platforms allow uploading scripts for multiple scenes at once. This could be a feature to explore.

Efficient Media Library Use

If you start using your own images or backgrounds, keeping them organized in Synthesia's media library (if available) will help.

Try This: Try duplicating a scene in the project you just made. Only change the script. You'll notice the time saved.

Sometimes, things don't go perfectly smoothly, especially when you're new to a tool. Here are a few common issues and how you might fix them:

Problem	Solution
Video generation is slow or seems stuck.	First, check your internet connection. Also, the Synthesia platform itself could be busy. Video length and complexity also play a part. If it's really stuck, try generating a much shorter segment or just one scene to test.
The avatar's pronunciation is off for a specific word.	This happens sometimes with AI voices. You can try spelling the word phonetically in the script box (e.g., “aw-sum” instead of “awesome”). Some tools support SSML tags like `<say-as interpret-as="spell-out">word</say-as>` for spelling, or you could just rephrase the sentence.
The audio sounds a bit robotic or unnatural.	Experiment with different AI voices; some sound more natural than others. Adding more natural pauses using punctuation (commas, periods) or specific break tags (like `<break time="500ms"/>` if supported) can help. Varying your sentence structure also makes a difference. I've found shorter sentences often sound better.
Elements in the template are not quite where I want them.	Most templates allow some basic customization. You can usually click and drag elements like text boxes or the avatar to reposition them. Resizing might also be possible. Keep it simple for now, but explore these options later.
“Where did my generated video go?”	Remember to check the “My Videos” section in your Synthesia dashboard. Also, Synthesia often sends an email notification when your video is ready.

Quick Task: If you noticed an odd pronunciation in your first video, try to correct it using a phonetic hint in the script and regenerate just that short scene.

You've learned basic avatar selection. But Synthesia often offers more ways to customize your AI presenter. These can add a nice touch to your videos once you're comfortable with the basics.

Beyond just picking an avatar, you might find options for:

Changing avatar outfits: Some avatars may have different clothing styles you can select.
Micro-gestures or expressions: Simple toggles might be available to add subtle hand movements or change facial expressions slightly.
Background changes: You can often change the background behind the avatar, either using Synthesia's options or uploading your own.

For these more detailed customizations, I recommend checking Synthesia's own advanced tutorials or their help documents. Think of this as “what's next” after you've mastered this quick 15-minute video creation. Now, you can explore the avatar settings in Synthesia. See if you can find where to change an avatar's outfit or background style for your next project.

You've taken a great first step into AI video creation with Synthesia. The key now is to keep practicing. Try making slightly longer videos, or ones with a bit more complexity.

Here are a few common questions beginners often ask after trying Synthesia:

Can I use my own voice with Synthesia avatars?

Synthesia primarily uses its library of high-quality AI voices. Some advanced plans or features might offer voice cloning, where you can upload your own voice. For that, I'd suggest checking Synthesia's latest feature list or specific guides on voice cloning.

How many languages does Synthesia support?

Synthesia supports a very large number of languages, often dozens. This allows you to create content for a global audience. For the most current and specific list, it's always best to check Synthesia's official website or their voice library.

Is there a limit to video length on the free/basic plan?

Yes, free trials or entry-level paid plans usually have limitations on video length per video, or total monthly generation minutes. These limits vary, so I recommend looking at Synthesia's current pricing page for the details on each plan.

Can I change the background music in templates?

Many Synthesia templates come with placeholder backgrounds or allow you to add media elements. Changing or adding background music is often a feature. You might find options to upload your own music track or select from a library provided by Synthesia. Check the scene editing options for “Audio” or “Background Music.”
