Once the Encoding profiles are created, the next step to controlling the quality of your video is to create Stream Groups. Since Stream groups are the grouping of different encoding profiles it may be likely to have stream groups for single video, Dual video, and Video plus slides among others.
The most difficult part of creating stream groups may be determining what stream groups need to be created. Once that has been determined, it is just a matter of adding a new group and choosing the encoding profiles to apply to each stream.
