This version of the Worship LIVE! software supports using video clips as backgrounds for projection. You can use any video clip that you may otherwise project from the software.
To select a video background, use the same techniques as for any other projection formatting, including setting the default projection formatting.
When you switch between items with different background videos, there will be a delay while the first video is stopped and the second video is started. This is normal.
You may find that the smooth fade transition type between items with the same background video does not produce pleasing results. The Transitions control on the playlist allows you to select a video-background-specific transition type.
