Storyline - video with graded question quiz (pause, play, rewind)

Thank you for the information but this is not what I am trying to do. I have a video with graded questions throughout the video. So as the video is playing a question will come up causing the video to pause and once the question has been answered the video continues. What I am trying to do is give the user the ability to pause the video on their own and then continuing playing the video.
