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:

http://www.superlectures.com/EVENT/stats

e.g. http://www.superlectures.com/odyssey2012/stats

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.

How to embed the SuperLectures videoplayer into your website

The new SuperLectures player can easily be embedded into your website. So, if you had an interesting talk or found something worth "sharing", do not hesitate and allow users to directly watch the lecture from your website. Here is a short how-to-do:

1. Open the talk at SuperLectures.com and switch to the share tab. Then copy the <iframe> code.

2. Paste the code into your post (in HTML mode). If needed, modify the size of the player by setting the height and width parameters.

How to share the best moment..

Hi folks,

We have added a simple feature allowing you to share a moment in the video. What is it good for?

• There is something interesting or funny you want to share with others...
• You are a lecturer and people often ask you to explain something. If you have already spoken about it, then send them a link with a particular time in your lecture. They can watch directly the part of your lecture where you are explaining the problem. You save their time...

To share the moment just click on a checkbox under the video...

...and then use one of the share buttons on the right.
