Mastering the Synthesia Editor | Synthesia Docs

The Synthesia editor

There are 5 main sections of the editor:

Toolbar

The toolbar is where you can go to access the video actions menu, set a title for your video, undo and redo actions, add elements to the canvas, add comments and collaborate with invited users, preview a draft of your video, and generate your video.

Video actions menu

Click the hamburger icon next to the video title to adjust the following video settings:

Video size

Create your video in one of several aspect ratios—we recommend selecting an aspect ratio before designing your scenes:

Name Ratio Width (px) Height (px)
Landscape 16:9 1920 1080
Portrait 9:16 1080 1920
Square 1:1 1080 1080
Tall 4:5 1080 1350
Wide 5:4 1350 1080

Version history

Every 30 minutes, a snapshot version of your video is auto-saved. A snapshot version is also saved each time you generate a given video.

Restoring and duplicating snapshots

To restore (or duplicate) a given snapshot of your video:

  1. Click the hamburger menu icon at the left of the toolbar to access the Video actions menu.
  2. Select the Show version history option.
  3. Access the Version history list on the right side of the editor.
  4. Select the version you wish to restore or duplicate from.
  5. To restore this specific version:
  6. Hover over the version and click the three dot menu icon next to the version name.
  7. Select the Restore option from the context menu.
  8. Click on Restore in the upper left corner of the page.
  9. To duplicate this specific version:
  10. Hover over the version and click the three dot menu icon next to the version name.
  11. Select the Duplicate option from the context menu.
  12. Click on Duplicate in the upper left corner of the page.

Note:

While the Version history includes which collaborators were editing a video at the time a given snapshot was auto-saved, or the collaborator who generated the video, granular information about who made which specific edits is not logged.

Elements

In the center of the toolbar is a selection of different types of elements you can add to the canvas for the scene you're currently in.

Comment mode

Click on the Comment button or use a keyboard shortcut to enter or exit comment mode.

Enter/exit comment mode (Mac) Enter/exit comment mode (PC)
+ c Ctrl + c

In comment mode, you can navigate to different scenes and add comments by clicking on the canvas.

You can reply, @mention other collaborators, react with emojis, and resolve comments. Click on the 3-dot icon to copy a link to the comment, edit your comment, or delete it.

You also have the option to move a comment to a different part of the canvas by clicking and dragging it to the desired location.

Comment panel

Comments on each scene will be visible on the left in the comment panel.

From the comment panel:

Collaborate

Click on the Collaborate button to share the current video with another Synthesia user. The shared video will appear in their Shared with me page:

Add the email of someone you'd like to collaborate with and chose one of the following level of access:

You can also adjust your general access settings to apply any of the above options to all users in your workspace.

Preview video

Click on the play button in the upper right corner of the page to launch a preview of the entire video. You should always launch a preview before generating a video in order to verify that everything is in order.

Note:

Generate

To generate your video, click on the Generate button at the right of the toolbar. This will open up the generate panel, where you can adjust the following:

Video captions

Your video's captions depend on the script you've added to your scenes. When publishing videos using Synthesia's video player, your viewers will be able to toggle captions on and off on their own, unless they have been burned-in, in which case they are permanent.

Burned-in captions are most useful if you are downloading your video to upload to another platform that doesn't have the option for uploading a subtitle file. You can download subtitle files for your video in .srt and .vtt formats from the video overview page.

Issues

If there are any issues preventing generation of your video, like unsupported characters in the script or lack of permissions for an avatar or voice, you'll be notified in the issues section.

You'll be shown a list of issues that you can click on, then navigate directly to the scene with the issue so you can fix it and generate your video:

Scene list

A Synthesia video is composed of multiple scenes in a row, linked by scene transitions.

Note:

The maximum amount of scenes per video is 150 scenes, each up to 5 minutes long—in total, a Synthesia video can be up to 4 hours long.

New scene

Select the + on the left panel to add a new scene to your video.

You'll have the option to add a layout (or all layouts at once) from the current template you're working from, or go back to select a template from Synthesia's stock template library or one of your custom templates so you can mix and match.

Scene transitions

To add a transition:

  1. Make sure you don't have any elements selected in the canvas (press Esc on your keyboard to deselect anything that's currently selected).
  2. From the inspector panel on the right, toggle the scene transition setting on.
  3. Select the desired transition.
  4. If desired, click Change all in the pop-up that appears at the bottom of the editor to update all transitions for your scenes to be the same as the transition you just selected.

To add music to a scene:

  2. Turn on the Music toggle from the inspector panel on the right.
  3. Choose from your music asset library or the Soundstripe library. Use the search bar to find specific tracks and preview them. You can filter your music tracks by Genre, Mood, Duration, or Instrumental.

  5. If desired, click Change in the pop-up that appears at the bottom of the editor to update all music for your scenes to be the same as the transition you just selected.

Once music is added:

Music upload

There are two ways to upload your own music to add to your scenes:

  1. From the music menu in the editor, by clicking the Upload music button.
  2. From the Library page.

Supported formats: mp3, .wav, .ogg, .aac, and .flac.

Canvas

The canvas is where you design the visuals for each scene. Add elements to the canvas from the toolbar, then animate, edit, and customize them as desired.

Inspector panel

The inspector panel is on the right side of the editor.

Script box

The script controls what is happening in your scene, use it to set the avatar that is speaking, its language and voice. Use triggers to trigger animations for elements based on the words in your script.
