Before we start describing numbers and charts, we would like to get you acquainted with events we are monitoring. Our aim was to build a system collecting information about every important action that users perform while using SuperLectures.com. These are events like when users start/stop watching the video, seek to a different time, replay a video part, click on a slide/link and many others. Having acquired a substantial amount of data, we have decided to build stats pages showing how users watch any video. To display nice interactive charts, we used very powerful Google Charts Tools.
Our stats pages are available at:
e.g. http://www.superlectures.com/odyssey2012/statsNow, let us introduce you several charts that SuperLectures.com provides. The first one is the daily audience chart. It displays how the whole event or a single video recording gained its audience through time. To deeper understand video daily audience, we plot two lines.
To see only basic stats data, you can switch to the information tab in our multimedia player. Below stats information text and graphs, there is a link for more complex data and interactive charts.
- Views - the number of video views with a reasonable playback time
- Well-Replayed - the playback time as a fraction of the video length (1 = playback of the whole video)
The audience engagement chart comes greatly in handy to detect moments when any video recording loses or gains its audience. If the video recording is boring, people will probably stop watching it or try to seek for some interesting parts. Moving the cursor over any chart line, you will see a value in percent showing how much any video part was viewed. If you click, the video player starts playing the video from that moment. Displaying also a line of audience engagement in all event recordings, you can easily compare how well any single video recording performs - if it has been viewed above average, has kept its audience and vice versa. Usually, long video recordings lose its audience more than short ones. So, when comparing, consider also the video length.
