It looks like you are looking at yesterday. It either may be too early for that data to be returned accurately (Sunday is the weekend; so not a business day), or as the picture is showing, you got no clicks and no impressions; which would return the RPM you see.
You need ad clicks/impressions to actually have an RPM of any sort, and one single video isn't going to hold people's attention for very long. What kind of video is it? Suggest you post more videos as soon as possible.
