When you select a layout with multiple regions, you can add a playlist for each region. However, when you play multiple playlists at the same time, performance may be affected.
To solve this performance issue, you can decide which region of the layout is optimal to play your assigned playlists, by defining the area as Primary or Secondary Playlists.
1. Selecting a Primary Playlist means all the Playlists you add to the region will play optimally: transitions and Display mode (fit to screen, fill screen) will work correctly.
2. Selecting a Secondary Playlist means all the Playlists you add to the region will be affected: Only Jump cut transition will work, video will be muted and Display mode will only work witFill screen".
To set the Primary and Secondary Playlist, just hovel the small number icon on the corner of each region inside the preview area of the campaign and click on the button "Set as Primary" or "Set as Secondary".
