What is the length of a continuously replayed part of video?

As we mentioned in our previous post, we filter out continuously replayed segments (views) shorter than a magic length. So let us talk a bit about this magic length.

We are monitoring which part of video is being played. Each time you seek in video, click on a slide or follow a search result, you start to replay a new segment of video.

Now, please take a look at the following figure:

As you can see, there are 4 segments. First, the user started to watch the video from the beginning. After a while, he found it probably boring, so he jumped a little bit further. Then, he went through slides and found one interesting slide, so he clicked on it and jumped into the last quarter of the video. Finally, an interesting keyword came to his mind, so he searched for it and found an occurrence of the keyword in this video. He jumped to that part of the video where the keyword was spoken and watched for a while.

We monitor such events. When we sum up all segments and plot a histogram out of them, we get a graph like the following one:

SuperLectures gets detailed video stats

After a month of development, we release playback and traffic statistics that SuperLectures.com is continuously collecting. Unlike common video servers (YouTube, Vimeo), SuperLectures.com provides you with detailed video statistics (similarly to Wistia). SuperLectures.com reveals how much users get engaged while watching video recordings.

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:

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.

Barcamp Brno 2012: Stats from the first 24 hours

Hi Barcampers,

We have a few interesting numbers from the first 24 hours of the published videos from Barcamp Brno 2012. So, congratulations to all speakers on nice presentations and all visitors who attended Barcamp in person or watched online. We published the video recordings on Monday noon, July 2nd 2012. The information spread within 1 hour through Twitter and we were waiting to David Grudl with his closely 9 thousand followers to tweet that his talk had been published :). David, thanks for a nice traffic peak.

Several more stats during the first 24 hours..

• There were closely 1800 unique visitors (Google Analytics) and 2000 unique IPs.
• There were 2 millions seconds of video replayed (it is 555 hours). Only 28 hours of videos were published by the way.
• Barcampers are everywhere (Google Analytics geolocation statistics).

And finally, here are the top 20 most viewed lectures.

Congratulations to BUT FIT students...

...because they made the same peak traffic on SuperLectures as ICASSP and Barcamp conference attendees - see the analytics graph.
Over 400 students of bachelor ISS (signals and systems) course visited 13 lecture recordings over 1200 times in (and only in) one day (really intensive study :).
To compare, the ICASSP conference had over 2000 attendees and Barcamp had over 300 attendees.

Good work guys.
