You can create a more interesting and visually-compelling videotaped deposition by showing the witness an exhibit every so often. When you are preparing for trial, you can set up the video playback to display the exhibit on the screen as the witness is being questioned about it. This will break up the monotonous continuing screen-shot of the witness which becomes tedious after ten or fifteen minutes.
