One of the most advanced filtering tools in Nacsport is the Descriptor Calculator, which can be used to search by time in both the timeline and the dashboard. This tool focuses on descriptors and offers an in-depth search that can reveal valuable information to the analyst in just a few clicks.


Nacsport Elite users have the full range of Nacsport tools at their disposal but, occasionally, advanced tools like this can slip through the cracks, either because they are unaware of it or are not completely sure how it works.


And, presumably, that’s why you’re reading this article. You want information on these useful features and that’s exactly what we’re going to show you today…the Descriptor Calculator.


So, let’s get started…



1. What Is the Descriptor Calculator Tool?
          1.1. Adding Search Results as Descriptors
          1.2  Labels in the Dashboard


2. How the Search Function Works
          2.1. In the Timeline
          2.2  On the Dashboard


3. Try it Yourself


What Is the Descriptor Calculator Tool?


Basically speaking, this is a search and filtering tool which allows you to find everything that happened between two specific actions with a specific duration.


Ok, we admit, this might not be a clear explanation, so let’s take a look at the practical application of this. With this tool, you can, for example, find all the descriptors that were tagged from when your “Attacking” category was activated until you click on “Ends in Shot On Goal”.


But not only that, you can also add up to three time criteria so that, in the above example, you can find all the attacking actions which ended in a shot on goal that lasted less than 15 seconds, which we can label “Flash”, those which lasted between 16 and 40 seconds, which is a “Medium”, or plays which lasted longer than this, which we can call “Long”.

Adding Search Results as Descriptors


Ok, you might be wondering what is the purpose of the above-mentioned naming system. Well, these categories can then be added to your analysis as descriptors, meaning that those specific attacks, “Flash”, “Medium” and “Long”, will be tagged alongside the rest of your descriptors.


This is especially useful when working within the Nacsport data matrix, since they will now be added as separate descriptors and you can access those clips quickly and easily.

In addition, this tool allows you to save the search criteria in the form of labels so that, when you open another analysis, you don’t have to set the criteria again. Instead, you simply load the saved labels and the program will search automatically for clips that fulfill this criteria, automatically adding these descriptors.


Labels in the Dashboard


But that’s not all…you can also create tags without having to add the descriptors. How? Very easily. All you have to do is open another analysis and, in your dashboard, select the option “Descriptor Calculator Label”.


Now your dashboard will show a label with the total number of actions produced with the saved search criteria, without the need of going to the timeline to load and activate the labels in each new open analysis.


And that’s why this is considered to be one of the most advanced filtering tools in Nacsport. It allows you to get a huge amount of data in just a few simple clicks. A very useful tool.


How the Search function Works


Ok, hopefully you’ve got more of an idea of how useful this tool can be, so let’s take a look at how it actually works.


In the Timeline

This tool can be opened by clicking on the magnifying glass and clock icon. A window opens where you need to select a category (we usually recommend that you choose a manual category such as “Attack”, “Possession” or “Defense” to get the most out of this tool) and choose the two descriptors that we need. By default, the Start and End options will be added, which marks the start and end times of the selected category.



Once you have selected the descriptors, enter the desired criteria on the right and give the search criteria a name. This name will be how the new descriptor will be added as, as well as the how labels will be known as when you create them in the dashboard. You can save as many criteria as you deem necessary.


On the Dashboard


If you want to have labels in the dashboard with the selected criteria, simply click on the dashboard and create a descriptor calculator label. As simple as a couple of clicks. You’ll now be able to see and review all the actions produced under these criteria.

Try it Yourself


Ok, this is honestly a tool which can add great depth to your analysis, so what better way to prove it than to try it for yourself. Add your own search criteria and set your own parameters until you find what works best for you. If you’re a Nacsport Elite user, open the program and try it out right now.


If you're not an Elite user, but think this could be useful, why not start thinking about an upgrade. Elite will give you access to this tool, as well as many more advanced tools to aid your analysis work.
