Below is an embedded mp4 video. It is important that you take careful note of the code in red as the height and width may affect whether the controller (Play/Pause) area shows up. Note the pathway to the mp4 file in shared documents. The path below points to the tread.mp4 file I have in my Shared Documents folder. You may adjust this pathway to the location of your file.

Please note the following areas in red that you will need to change.
