As the board size can change from board to board, it's not easy to make good videos using Camtasia. My fastest recorded intermediate game shows the third-best time I ever played (12.37 seconds, non-flagging). Luckily, I even have a video of my expert record of 56.85!
As my new expert record was played with Nonosweeper version 2.1.5, I can offer at least a video from playing the replay.
