As described in the latest update/release notes from Echo360, Add and Remove tracks allows you to start with a piece of media with one track and add other tracks to it (up to a total of 3 tracks). Or, conversely, you can start with a piece of media that has multiple tracks and remove or replace tracks down to 1 remaining track. You can continue to trim segments from both the original and the added media until you have a compilation that works for you.
This feature allows you to stitch together recordings that may have been captured separately for whatever reason but are better viewed together. It also allows you to remove or replace input sources that are not wanted, perhaps due to not recording correctly.
For more information, see Adding, Removing, and Replacing Video or Audio Tracks in Echo360's online support resources.
