Playing Videos in Photo Album Slideshow
If you added videos to your Website Builder slideshow, they play automatically as the slideshow rotates through the pictures and videos. If you set music to your slideshow, it fades during a video, but continues playing in the background.
You can control the music's volume using the volume control. The background music returns to regular volume when the video is complete.
The slideshow resumes rotation after the video completes. If you pause the video, the slideshow is paused. The slideshow does not continue until the video completes. Pausing the slideshow, pauses the video, too.
