Reactions let viewers respond to your video with an emoji at a specific moment, and they are on by default for new videos. Turn them off per video in Share → Viewer settings. Reactions appear as emoji markers on the video timeline, so you can see exactly where viewers engaged.

​
Turn reactions on or off

Reactions are enabled by default on new videos. To toggle them:
  1. Open your video in the Tella editor.
  2. Click Share in the top right.
  3. Click Viewer settings.
  4. Toggle Reactions on or off.
When disabled, the reaction bar and timeline markers are hidden from viewers on both the view page and in embedded videos.
To change the default for new videos, go to Settings → Preferences and toggle Show reactions.

​
Add a reaction

While watching a video, viewers can add an emoji reaction at the current playback position:
  1. Click one of the emoji options in the reaction bar.
  2. The emoji animates to the timeline and appears as a marker at that timestamp.
Both logged-in users and anonymous viewers can add reactions.

​
See and remove reactions on the timeline

All reactions from viewers are displayed as clustered emoji markers along the video timeline. Clusters group nearby reactions together, so you can quickly see which moments resonated most. Hover over a cluster to see the individual emoji counts. Your own reactions are highlighted with an outline. On the video’s page on Tella, click a highlighted emoji to remove one reaction, and repeat for any other reactions you want to remove. Removing reactions isn’t available from embedded videos. Clicking an emoji in the reaction bar always adds a new reaction. There isn’t currently an option to remove all reactions at once. Turning reactions off in Viewer settings hides the reaction bar and timeline markers, but doesn’t delete existing reactions.

​
Reactions vs. comments

Reactions and comments serve different purposes:
  • Reactions are quick, low-friction emoji responses tied to a moment in the video. They require no text input.
  • Comments allow detailed, text-based feedback and support threaded conversations.
You can also add emoji reactions to individual comments. See Comments for details on comment reactions.
