How do you change the background for a video? The video does not take up the entire slide, so does it just have to be black?

    You can change the settings, . After your video is uploaded, click "Change Video" again. At the bottom you will see choices to "fit" the video to the screen size. For instance, a "letterboxed" video such as the one in my example, can be adjusted to "fit to height." If your video is 4:3, like the video in my second screenshot, then you would want to choose "fit to width." If you choose to fit the video to height or width, I would recommend watching it all the way through afterward. All that these adjustments do is "zoom in" on the video and you will be losing some of the video (at the sides in my first example and at the top and bottom in my second). As far as changing the background color you would have to do that in Settings > Default Media. *BUT* You would have to set your video as the default video. To do this, choose Video in the dropdown for Service Item/Quick Screen. Under the Background dropdown you would be able to choose a fill color. After that, whenever you add a Video service item it will add it with that original video. You can then change the video to something else and if that video doesn't fill the full screen the color you chose when creating this default for videos will fill in the rest of the screen.

  2. I just saw that you don't have to change the default media, . Click Change Video and all of those fill colors are there in that dropdown -- duh :-)
