                          at t=10 video1 (1st interval) starts 5 seconds into the video.
                          at t=11 video1 (1st interval) disappears.
                          at t=11 video2 (1st interval) disappears.
                          at t=11 video1 (2nd interval) restarts 5 seconds into the video.
