When you add your Labels, Glean offset's the start time by a minimum of 3 seconds. Glean goes back 3 seconds, and then back a little bit further to the start of that audio bubble. This makes sure that all the relevant audio is covered when you add your label.
Adjust the Timing
You can manually adjust the start and end time of any of your labels.
- Select the Label you want to edit
