Unfortunately there currently isn't a way to force a student to stay on a page for a specified period of time before enabling the link to move on to the next page. That said, it might be possible for a teacher to craft some sort of JavaScript that could disable the button for a fixed period of time. Unfortunately, any tech-savvy student will be able to work around this easily.
You could probably use clusters to accomplish the part where student will get an unseen page each time they attempt the questions related to the video.
Hope that helps.
