You can use a phone, tablet, video camera or DSLR.

To film with a phone or tablet, you need to use the Protern Video app for iOS or Android. 

If you use a video camera or DSLR, the camera requires a microphone input where you can plug in a linear timecode (LTC) generator. 

The Protern Clock app for iOS or a Dish LTC Generator can be plugged into your camera. 

A Linear Timecode (LTC) generator produces an audio timecode that certain software can decode to understand exactly when each frame of the video was recorded.

The Protern Clock app for iOS or a Dish LTC Generator can be plugged into your camera.

No. Protern Video automatically links the video using the GPS run data.

Yes—and you can synchronize two videos and compare their line and technique differences, along with direct speed and time comparisons.

No! Protern Video can be used for Ski Cross, Snowboard Cross and Alpine Snowboard racing. 

You can also use it during drills to evaluate how smooth the athlete is, or their symmetry. 

Once a video is imported into Protern Video, if the sensor data and quantriq has already been uploaded to Protern, the data overlays will be available immediately.  

No uploading videos to the web is required. The videos stay on your device for more powerful and faster analysis. 

For Protern Video to identify your athletes automatically, you will need to upload their sensor data and make a quantriq first. When you import the video, Protern Video will check to see which quantriqs happened at the same time as videos and display a list. 

Once you pick the quantriq, Protern Video will check who was skiing the course at the exact time of the video. If more than one athlete was on the course at the same time, the app will show the possible matches.

Yes, you can film non-Protern athletes. While there won’t be any data overlays or automatic athlete naming, you can still playback the videos, zoom in, and do side-by-side comparisons.

If you do a side-by-side comparison between a non-Protern athlete and a Protern athlete, you’ll see the speed of the Protern Athlete displayed. This can helpful for estimating the speed of the non-Protern athlete.

When filming with a video camera equipped with a Dish LTC Generator, the accuracy of the sync is less than 0.01s. Using Protern Clock app with your camera or the Protern Video app to film, the accuracy of the sync is closer to 0.02s.

Protern Video app is free.

To sync your video with the new Protern data, a valid Protern Pass is required. Otherwise the analysis, comparison and basic sharing is still available.

In order to get an accurate sync between the video and data, it is required to film using the Protern Video app. The default camera app’s timecode can be off by up to a few seconds, resulting a incorrect and unusable sync.

Yes! You do not need a Protern account to view Protern Advanced Videos. These .protern files include the video, as well as all the data for the overlays. So even parents can play with the dynamic data overlays, do side-by-side video with direct data comparisons, as well as share the files with grand-parents.

Certainly! As long as the athlete is wearing a Protern sensor and you film with either the Protern Video app or a video camera with an LTC generator, you can sync the data.

Filming races and syncing data is very helpful for understanding the speeds reached in racing. This can help inform your train protocols.

Protern Video requires an internet connection to download the data to merge with the video. It is a very small amount of data, so if you have a poor internet connection, it shouldn’t impact your video analysis. There is no need to upload your large video files to the web.

Protern Video also doesn’t need an internet connection to share videos. You can use AirDrop, USB key, or hard drive to transfer videos.

All your videos on your device, or that saved elsewhere, will still be viewable, along with the data.

A valid Protern Pass is required to link videos with new data.
