How to Use Synthesia in 2025: Complete Beginner’s Guide (Step-by-Step)

📋INTRODUCTION

If you’ve ever wanted to create professional-looking videos without a camera, a microphone, or any video editing experience, Synthesia is exactly what you’ve been waiting for. It’s an AI video generation platform that lets you turn a plain text script into a polished video featuring a realistic AI avatar — no studio, no crew, no on-camera nerves required. Whether you’re a solo entrepreneur, a corporate trainer, a teacher, or a content creator, Synthesia removes every technical barrier that used to make video production feel intimidating or expensive.

This guide is written specifically for complete beginners who have never used Synthesia before. You don’t need a background in design, video editing, or AI to follow along. By the time you finish reading, you’ll know how to create your free account, build your first AI video from scratch, customize an avatar, add your own branding, and export a finished video you’re genuinely proud of.

We’ll walk through every core feature step by step, flag the most common beginner mistakes so you can skip them entirely, and share pro tips that will help your very first video look like it was made by someone who’s been using the platform for months. Let’s get started.

📝CORE FEATURES HOW TO

FEATURE_1_TITLE: Choosing and Customizing an AI Avatar
FEATURE_1_HOW_TO:
1. Inside your video project, click on the avatar displayed on any slide to open the Avatar panel on the right side of the screen.
2. Browse the avatar library — Synthesia offers 230+ stock avatars of different genders, ethnicities, ages, and professional styles. Use the search bar or filters to narrow down by appearance or style.
3. Click on any avatar to preview how they look, then click “Apply” to swap them onto your slide.
4. To change what the avatar is wearing or their background, look for the “Style” options within the avatar panel — some avatars have multiple outfit variations.
5. If you want the same avatar used across all slides, right-click on the avatar and select “Apply to all slides.”

FEATURE_2_TITLE: Writing and Editing Your Video Script
FEATURE_2_HOW_TO:
1. Click on the script text box below the video preview area on any slide — this is where you type exactly what you want your avatar to say.
2. Type or paste your script directly into the text box. Synthesia’s AI will convert every word into natural-sounding speech delivered by your chosen avatar.
3. To control pacing, add a period or a comma where you want the avatar to pause slightly. For a longer pause, type [pause] in the script.
4. Click the play button above the preview area to hear a real-time audio preview of how the script sounds before you generate the full video.
5. To add a new slide, click the “+” button in the slide panel on the left, then repeat the scripting process for each new section of your video.

FEATURE_3_TITLE: Adding and Editing Visual Elements (Media, Text, and Backgrounds)
FEATURE_3_HOW_TO:
1. Click anywhere on your slide canvas (not the avatar) to open the editing toolbar on the right side of the screen.
2. To add a background, click “Background” in the right panel and choose from solid colors, gradient options, images from the Synthesia media library, or upload your own image.
3. To add a text overlay, click the “Text” element in the toolbar and drag it onto the slide, then type your heading or caption.
4. To insert an image or video clip, click “Media” and either upload your own file or search the built-in stock library powered by Unsplash and Pexels.
5. Resize and reposition any element by clicking and dragging it on the canvas, and use the alignment guides that appear automatically to snap elements into place neatly.

FEATURE_4_TITLE: Generating, Downloading, and Sharing Your Finished Video
FEATURE_4_HOW_TO:
1. Once all your slides are scripted and designed, click the green “Generate video” button in the top right corner of the editor.
2. Synthesia will process your video — this typically takes between 5 and 15 minutes depending on the length and complexity of your project. You’ll receive an email notification when it’s ready.
3. Preview the full generated video in the Synthesia player to check for any errors in speech, pacing, or visuals before you share it.
4. If something needs fixing, click “Edit video,” make your changes on the relevant slide, and click “Regenerate” — only the updated slides will re-render, which saves time.
5. When you’re happy with the result, click “Download” to save the MP4 file to your computer, or click “Share” to generate a private link you can send directly to others without requiring them to have a Synthesia account.
