This documentation provides specific information on annotating and reviewing data groups - including multi-modal groups in the Label Editor.

​
Synchronize Playback

You can synchronize playback for all audio and video files. When enabled, playback on all media files occurs simultaneously.
  1. Open the Data Group in the Label Editor.
  2. Click the Synchronize timeline across files button in the top-right corner.
To ensure all data units remain in sync, make sure they are all the same duration.

​
Single Editor Timeline Setting

To display only a single editor timeline for groups of data:
  1. Navigate to the General Settings.
  2. Enable the Single synchronized timeline toggle.
The single editor timeline only shows annotations on the tile currently selected for annotation or review.

​
Review Data Groups

Reviewing data groups requires you to switch between tiles to view annotations on each data unit. You can switch tiles by:
  • Selecting the tile in the left-side menu.
  • Clicking Review from this tile on a specific tile.
Both methods are synchronized. For example, clicking Review from this tile on a tile also selects it in the left-side menu.
