Live Channels Settings

In Kollus Live, a channel is the most essential unit for operating and managing live streams. It converts (transcodes) the original video in real time and delivers it in a format optimized for viewers, while providing an environment where multiple Creators can operate broadcasts.

Create a new channel

Creating a channel issues an RTMP address for stream broadcasting and a URL for viewing the broadcast.

Channel creation permissions

Only service accounts assigned the super administrator role can create channels.

1. Click Kollus Live console > [Channel] > [Channel list] > [Register channel] at the top right of the screen.
   
2. Configure each item. (Refer to the Channel detail settings section)
3. Configure additional features via the tab menu at the bottom of the screen. (Refer to the Bottom tab settings section)
4. After completing the settings, click [Save].
