If you want to upload a recorded livestream to a specific channel in VideoManager Pro, this video inherits the owner group of selected channel automatically. 

If you want to upload a recorded livestream to more than one channel, a copy of the video will be made for each channel. Each video inherits the owner group of selected channel automatically.

If you want a Webcast playout in "On Demand" mode, the video of the first selected channel will be used.
