I’ve noticed that none of my media has any distance count information on it once I try to play it on my computer. Why is this?

By default, the CS10 software shows you the Count information, but does NOT record this information to the actual media.
In order to stamp your media with Count information, you will need to navigate to Menu > Settings > Overlay and turn it on.
In order to do this, you will need a SeeSnake CountPlus on your SeeSnake Reel.
