How Synthesia Actually Works
Understand the platform before you build anything

Learning Objectives

  • Understand what Synthesia is and what it produces
  • Navigate the dashboard and find every feature you need for your first video
  • Explain the scene-based structure so you can plan your video before you build it

What Synthesia Is — And What It Is Not

Synthesia is an AI video generation platform. You type a script. You choose an avatar — a digital human presenter. You design what appears on screen alongside the avatar. You click Generate, and Synthesia renders a video — complete with lip-synced narration — without a camera, microphone, recording studio, or video editor.

The result looks like a professionally produced training video. Because it is one.

What It Is Good For

  • Training and onboarding videos your team will actually watch
  • Process walkthroughs and SOPs that used to live as text documents no one read
  • Compliance content that needs to be consistent, documented, and easy to update
  • Software demos combined with screen recordings
  • Content that needs regular updates — because editing is fast and cheap

What It Is Not Good For

  • Live, real-time content that changes daily
  • Moments where learners need to see a specific real person — a company founder, a patient, a key client
  • Highly interactive, branching simulations (use Articulate or similar for those)
💡 Pro Tip

If you are hesitating over whether to use Synthesia for something, ask yourself: "Would a recorded person be better — or just more familiar?" Most of the time, it would just be more familiar. Familiar and better are not the same thing.

Dashboard Orientation

Log in and take 60 seconds to orient yourself before you build anything. Here is what matters for your first video:

AreaWhat It DoesYour Priority
My VideosYour full video library — all projects live hereHigh — create a folder before your first video
TemplatesPre-built video structures to study or adaptMedium — browse one, then build your own
Media LibraryStorage for logos, images, screen recordingsHigh — upload your logo before building
Brand KitColors, fonts, logo applied automaticallyHigh — set this up in Module 4
New VideoCreates a new projectHigh — you will click this in Module 3
📌 Note

Before you build your first video, create a folder in My Videos. Go to My Videos → New Folder. Name it something like "Training Videos — 2026." An organized library from day one saves significant time later.

The Scene — The Most Important Concept in Synthesia

Every Synthesia video is made up of scenes. A scene is the basic unit — like a single slide in a presentation, except it also plays narrated audio. Every scene has three parts:

  • Script — the words the avatar speaks. You type this.
  • Layout — the visual structure. The avatar's position, background, any text or images on screen.
  • Avatar and voice — who delivers the narration and how it sounds.

When you click Generate, Synthesia processes every scene — synthesizing the voice, animating lip movements, compositing visuals — and stitches them into a single video file.

How Long Is a Scene?

Words in SceneApproximate DurationBest For
50 words~23 secondsIntro, hook, quick transitions
75 words~35 secondsMost instructional content scenes
100 words~45 secondsComplex steps or detailed explanations
150+ words70+ secondsGetting long — consider splitting into two scenes

A 5-scene video where each scene is about 75 words runs approximately 3–4 minutes — a solid, complete training video for most topics.

🏁 Quick Win

Your key takeaway: Synthesia = scenes. Each scene = one script + one layout + one avatar/voice. Plan your video as a list of 5 scenes before you open the editor. This single habit separates learners who feel in control from those who feel lost.

1. Which of the following is Synthesia best suited for?

2. A 5-scene training video where each scene is roughly 75 words will run approximately how long?

3. What are the three parts of every Synthesia scene?
