Preventing video Pausing on button click in course scene transition

Add a "mask" to the video.  Create a shape that completely covers the video. Format the shape to a solid fill but set the transparency to 100%.  Do not select "No Fill". It will treat the shape as hollow and allow users to click the underlying video.  A solid fill set to 100% transparent prevents the user from clicking the video which pauses the video. 

Then add any buttons you need on top of the "mask".  See the attached file. I left the outline visible so that you can see as you edit the slide.
