When you select a campaign layout with multiple regions for display, you can add a playlist for each region. Sometimes, there may be campaign performance issues when you play multiple playlists at the same time.
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, the video will be muted and Display mode will only work with "Fill screen".
To set the Primary and Secondary Playlist, just mouse over 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'.
Your Primary Playlist will have a '1' icon while your other playlists will become secondary playlists marked with a '2' icon.
