Integrating Protern.io data into video

Probably the most requested feature we have gotten, is the ability to sync Protern.io data with video. 

Comparing runs, setting unlimited splits and looking at speed profiles are great, but sometimes you want to see a video of what was going on. Being able to put the speed data on the video makes it even better.

With Protern.io’s latest update, you can easily download the data for a run as a CSV that can be imported into Dartfish (paid) or Dashware (free).  

Both of these tools are PC only, but Apple users don’t worry! We are working with a company to integrate Protern.io data into their Mac based video tool. We hope to be able to announce something soon.

Keep reading to see how you can get the run data for integration into video.

Filming: Frame rate

The Protern.io sensor captures data on the skier 10 times a second. Played at normal speed, the numbers fly by and it is difficult to see the impact of a turn on the video.

We recommend filming at least 60 frames per second. Even faster, such as 120 frames per second, will be even better.

The higher frame rate means you can slow the video down and be able to better see the data. The higher frame rate will also be easier to capture the exact moment the skier crosses the start split.

Filming: Keeping track of runs

You will need to make sure you can link the video with the correct run in Protern.io. 

We recommend the following process:

  1. Log into Protern.io and build a quantriq that roughly captures the course (you can refine it later)
  2. Using the Protern Sync mobile app, sync the athlete’s sensor
  3. On Protern.io, note the number of the last run for the athlete you will be filming (e.g. Run 2)
  4. Check the current time
  5. When filming, say “Protern Run 3 – Athlete name – Time of day”
  6. Repeat steps 2 to 5 for other athletes and/or runs

If for some reason you notice the runs on Protern.io don’t match the video, it is possible to match the runs to the time.

Download the quantriq CSV and look at the start timestamp for each run. Then you can link the timestamp with the time said on the video. 

To download the quantriq CSV, click "Show Details" and then "Export Data"

Getting the run data to integrate into the video

To get the CSV (commas separated value) file, just make a quantriq like you would normally. Ensure the start split is at a point that will be visible in the video.

To get the data, find the run you want and click on the option icon. Select “Download Section Data”. 

This will download a CSV of the run data. It includes the elapsed time from the first split, lat and long, distance covered from the first split and speed.

Video tools to integrate Protern.io data 

The two video tools that we are aware of that can take CSV data and sync it to video are Dartfish and Dashware.

Both of these tools are PC only, but Mac users don’t worry! We are working with a company to adapt their Mac based video tool to work with Protern.io data.

Dartfish

Dartfish is a premium video analysis product. The paid version of the tool can take CSV data and insert it into video. Here is a link to the instructions from Dartfish. 

Dashware

Dashware is a free tool made by GoPro. It is not the simplest to start using, but once you have it set it up, it is fast. The video included in this article was created with Dashware.
