Office Set up

Hi Malvika! If you use an image, you can rotate it to fit the horizontal background ipad. In your file though, it looks like you inserted a video over that background image. Since I don't believe you can't rotate videos, you can use a different background image to make the video appear on the ipad. If you click the Home tab>New Slide>Content Library 360, a box will pop up.

In the search field, type "media" and a whole bunch of slide options with screens on them will display. 

You can insert any of the slides you want into your project and switch out the media with your video. You can also remove any of the extra objects you don't want. Hope that helps!
