The video is blank for me for whatever reason, but possibly related to #660

@joshtrichards I must admit video is not veru clear, but it is not really blank, you can see the scroll bar move up and down on the right side of the video, and when I scroll too much, it disappears at the bottom <=> I can't see PDF page bottom
