Adding video to my Nova theme home page

Hello,
I am using nova theme version 1.9. It is an elegant theme and I want to have multiple videos playing on my home page, but I don’t know how to do this. I currently have one video playing, the theme is supposed to be able to have a few to choose from using a slider. I don’t know how to add another video and any help on this would be much appreciated as I am new to this.
Thanks
Greg
