Hi! I know this was posted a while ago but I thought I might as well still say something just in case other people were looking for an answer, as well.
Yes, students can jump around the video, and we are able to see their analytics for how much of the video they watched. While this might be setup or controlled by your organization that runs canvas studio, I do not think students can jump through questions, meaning they can only fast forward the video up until the next question, and they can only continue after the question has been answered.
Might be something to test in student view.
Hope this helps!
