Why Trust This Guide
I’ve used Synthesys for eight months and tested every feature covered here. This tutorial comes from real hands-on work, not vendor screenshots.
Synthesys is one of the strongest AI video generator platforms available today.
But most people only ever touch the voice tool.
This guide shows you how to use Synthesys end to end.
Step by step, with screenshots and the shortcuts I actually rely on.
Synthesys Tutorial
This tutorial walks through every feature in order.
It runs from first login to the advanced methods power users lean on.
The core concepts are simple, and you need no animation knowledge to follow along.
Synthesys
Make studio-quality videos without a camera, a crew or a single retake. Synthesys gives you 60+ AI avatars, 300+ lifelike voices and 140 languages in one dashboard. Try it free — no account or card needed.
Getting Started with Synthesys
Before any feature works, finish this one-time setup.
It takes about three minutes.
Here’s my own walkthrough of the platform first:
Now let’s break down each step.
Step 1: Create Your Account
Go to the Synthesys website and click Sign Up.
Enter your email and set a password.
✓ Checkpoint: A confirmation email lands in your inbox within a minute.
Step 2: Open the Dashboard
Synthesys is cloud-based, so nothing gets downloaded.
It runs in the browser and needs a steady connection to render.
Here’s what the dashboard looks like:
✓ Checkpoint: The sidebar lists AI Voices, AI Humans and the media tools.
Step 3: Set Your Brand Kit
Open Settings and upload your logo, brand colours and fonts.
The Brand Kit then applies the same design to every video automatically.
✅ Done: You’re ready to use any feature below.
How to Use Synthesys AI Voices
AI Voices lets you turn any written word into natural speech.
The library holds more than 300 ultra-lifelike voices across 140 languages.
Here’s how to use it step by step.
Step 1: Open the Voices Tab
Log in and click AI Voices on the left sidebar.
Pick the language you want before you write anything.
Step 2: Paste Your Script
Drop your text into the editor box.
Add commas and full stops where you want the speaker to pause.
Here’s what this looks like:
✓ Checkpoint: Your script sits in the editor with a word counter below it.
Step 3: Choose a Voice and Generate
Preview a few voices before you decide.
Click Generate, then download the file when the render has ended.
✅ Result: A clean voiceover file that sounds like a real human reading your copy.
💡 Pro Tip: Assign different AI voices to specific lines inside one project. Two speakers trading lines hold attention far better than one flat narrator.
How to Use Synthesys AI Human Avatars
AI Humans puts a presenter on screen without a camera or a studio.
Synthesys AI Studio offers more than 60 avatars built from footage of real actors.
Here’s how to use it step by step.
Step 1: Browse the Avatar Library
Open AI Humans and scroll the gallery.
Filter by gender, age range and clothing style.
Step 2: Match the Avatar to Your Purpose
A suited presenter suits finance content. A casual one suits tutorials.
Here’s what this looks like:
✓ Checkpoint: The avatar preview loads with your chosen voice attached.
Step 3: Add Your Script and Render
Paste the script, pick a voice, then hit Generate.
Most clips finish in one to five minutes.
✅ Result: A talking-head video with no filming, no lighting and no retakes.
💡 Pro Tip: Build a custom avatar of yourself in under 30 seconds. Familiar faces beat stock AI avatars for repeat viewers every time.
How to Generate Synthesys AI Media
Generate AI Media creates custom visuals from a short text prompt.
Synthesys runs a text-to-image engine for artwork, backgrounds and B-roll stills.
Here’s how to use it step by step.
Step 1: Write a Specific Prompt
Vague prompts give vague results.
Name the subject, the setting and the lighting.
For example: a bright office with soft window light.
Step 2: Pick a Style
Choose photoreal, illustration or 3D render.
Here’s what this looks like:
✓ Checkpoint: A grid of image variations appears under the prompt box.
Step 3: Generate and Compare
The platform returns multiple versions of the same prompt.
Save the one that fits, then continue building your scene.
✅ Result: Original artwork you own, instead of stock photos everyone else uses.
💡 Pro Tip: Try the Synthesys X Chrome Extension. It rebuilds any image you find online as an AI-modified version, cleared for commercial work.
How to Use Synthesys Face form
Face form builds a custom avatar from footage you record yourself.
Synthesys also offers an Avatar Builder if you would rather design one from scratch.
Here’s how to use it step by step.
Step 1: Record a Short Clip
Film 30 seconds facing the camera in even light.
Keep your head still and your mouth clearly visible.
Step 2: Upload and Train
Drop the file into Face form and wait for processing.
Here’s what this looks like:
✓ Checkpoint: Your face shows up in the avatar list with a custom tag.
Step 3: Save and Reuse
Name the avatar so you can find it later.
It now appears beside the stock avatars in every project.
✅ Result: A presenter that looks like you, ready for unlimited future videos.
💡 Pro Tip: Record in the exact clothes you want on screen. You cannot change the outfit after training, and reshooting wastes time.
How to Use Synthesys Lab
Synthesys Lab is where newer tools land before a full release.
The 2026 headline feature here is speech-to-speech, and it solves a real problem.
Here’s how to use it step by step.
Step 1: Open the Lab Tab
You will find it below the main tools in the sidebar.
Labelled tools may change without notice.
Step 2: Record Your Own Delivery
Read the script aloud with the emphasis you want.
Here’s what this looks like:
✓ Checkpoint: A waveform of your recording appears with a voice picker beside it.
Step 3: Swap in an AI Voice
Synthesys replaces your voice while maintaining your timing and speech patterns.
The emotional depth survives the swap.
✅ Result: AI narration that carries your own emphasis instead of flat text-to-speech.
💡 Pro Tip: Use speech-to-speech for sarcasm, questions and punchlines. Plain text-to-speech reads those flat no matter how you punctuate.
How to Use Synthesys Text-to-Video Generator
Text-to-Video Generation is the fastest route from idea to finished clip.
Feed it a prompt or upload a document, and artificial intelligence writes the script.
Here’s how to use it step by step.
Step 1: Give It Source Material
Type a one-line prompt or upload a PDF.
A blog post or a book chapter both work fine.
Step 2: Review the Generated Script
The AI video generator drafts the copy and matches scenes to it.
Here’s what this looks like:
✓ Checkpoint: A scene strip appears along the bottom of the AI video generator editor.
Step 3: Edit the Order and Render
Reorder scenes, cut weak lines, then generate.
Nothing is locked, so you can edit after the first render.
✅ Result: A full multi-scene AI video built from a single paragraph of input.
💡 Pro Tip: Never ship the first draft word for word. The AI writes clean copy, but it misses your specific product details.
How to Use Synthesys Multilingual Support
Multilingual Support lets one recording reach a global audience.
Synthesys AI Studio supports video creation in more than 140 languages.
Here’s how to use it step by step.
Step 1: Finish the Master Version
Build and approve your video in one language first.
Fixing errors later across 12 versions is the hard part.
Step 2: Select Target Languages
Open the language menu and tick each market you want.
Here’s what this looks like:
✓ Checkpoint: Each selected language shows as a separate render in your project list.
Step 3: Check the Timing
Translated lines run longer or shorter than the original.
Trim any scene where the voice overruns the visuals.
✅ Result: One script working across every market you sell into.
💡 Pro Tip: Voice cloning copies your voice into 29 languages while maintaining its character. Your Spanish version still sounds like you.
How to Use Synthesys AI Talking Photos
AI Talking Photos turns a single still image into a moving presenter.
Upload a photo and Synthesys animates the face to match your audio.
Here’s how to use it step by step.
Step 1: Upload a Clear Photo
Front-facing shots with both eyes visible work best.
Sunglasses and heavy shadows break the effect.
Step 2: Attach Your Audio
Pick a generated voice or upload your own recording.
Here’s what this looks like:
✓ Checkpoint: The photo blinks and moves in the preview window.
Step 3: Render and Review
Watch the full clip before you export.
Check that the mouth lands on each syllable.
✅ Result: A speaking presenter built from one image in under a minute.
💡 Pro Tip: Keep talking-photo clips under 45 seconds. The effect holds attention early, then small glitches start to show.
How to Use Synthesys Audio Translations
Audio Translations converts finished audio into another language.
This is the fastest way to communicate with viewers who do not speak English.
Here’s how to use it step by step.
Step 1: Upload Your Audio
Drop in an existing MP3 or WAV file.
Clean source audio translates far more accurately.
Step 2: Pick the Output Language
Choose your target language from the dropdown.
Here’s what this looks like:
✓ Checkpoint: A translated transcript appears next to the original audio.
Step 3: Export the New Track
Download the translated file and drop it back into your video.
The process takes minutes, not days.
✅ Result: A second-language version of content you already published.
💡 Pro Tip: Read the translated transcript before exporting. Product names and slang translate badly, and fixing them in text is quicker.
Synthesys Pro Tips and Shortcuts
After eight months inside Synthesys, these are the habits that saved me the most time.
To use Synthesys effectively, plan the script before you ever open the editor.
Keyboard Shortcuts
| Action | Shortcut |
|---|---|
| Play or pause preview | Spacebar |
| Undo last edit | Ctrl + Z |
| Duplicate a scene | Ctrl + D |
| Save project | Ctrl + S |
Queue long renders in one batch so the platform works through them efficiently:
Hidden Features Most People Miss
- Template variables: Swap a name or company field to bulk-generate a personalised video series from one master file.
- Multi-voice projects: Assign different voices to specific lines so a dialogue scene sounds like two real humans.
- Instant translation: Duplicate a finished project, switch the language, and you have a second market covered.
Synthesys Common Mistakes to Avoid
Mistake #1: Writing Like a Blog Post
❌ Wrong: Pasting long written paragraphs straight into the script box.
✅ Right: Write short spoken sentences. Read them aloud first and cut anything that trips you up.
Mistake #2: Making Videos Far Too Long
❌ Wrong: Cramming every detail into one twelve-minute clip.
✅ Right: Shorter videos get higher completion rates. Keep only the essential information and split the rest.
Mistake #3: Ignoring the Preview
❌ Wrong: Rendering all language versions before checking the first one.
✅ Right: Approve one master version, then translate. Fixing a script across twelve renders is pure frustration.
Synthesys Troubleshooting
Problem: The Voice Mispronounces Names
Cause: The engine reads unusual spellings using standard language patterns.
Fix: Spell the word phonetically in the script. Write “Fahim” as “Fa-heem” and it lands correctly.
Problem: Rendering Takes Too Long or Fails
Cause: Synthesys renders in the cloud, so a weak connection stalls the job.
Fix: Split long projects into shorter scenes. Four short renders finish faster than one long one.
Problem: Lip-Sync Looks Slightly Off
Cause: Fast pacing and dense sentences are difficult for the avatar to match.
Fix: Add commas to slow delivery. Balance the pace, then re-render that scene only.
📌 Note: If none of these fix your issue, contact Synthesys support.
