Take advantage of automatic and highly precise syncing of video to Protern data with these four items.
In order to automatically link your video to Protern data, you will need the following four things:
- Collect data: Protern
- Filming Option 1: Phone or tablet
- Filming Option 2: Video camera with LTC generator
- Analyzing video with data: Protern Video
- Alternative to Protern Video: Telemetry Overlay
Collecting data: Protern
Protern collects up to 5,000 data points per run. This includes time, speed and line. The app makes it easy to set splits anywhere on the course, giving you the option to see your speed and time coming terrain and course features.
All this information can be merged into video, making the video analysis look like World Cup live TV feed.
Where to buy: Protern Store, starting at $399 for first year
Filming Option 1: iPhone, iPad, or Android device
You can film your athletes with Protern Video using any relatively recent phone or tablet. The app embeds an very accurate timecode that allows it to sync the Protern data to the video. Simply record the athlete, pick their name the list and Protern Video will download and merge their data automatically when a quantriq is made.

Filming Option 2: Video camera and LTC Generator
Video Camera
A video camera is an obvious requirement, but the addition of the microphone port allows for the insertion of an audio timecode called LTC (Linear timecode - see below). This timecode lets Protern Video know exactly when the video was recorded, allowing it to line up the start of the video with the data very accurately.
LTC Generator
LTC, or Linear Timecode, is a 40 year old standard for an audio timecode that is used widely in the film and television industry. Protern has worked with various industry partners to adapt the use of LTC to allow for linking GPS timecoded sensor data with video.
There are two LTC generator options for sport:
| Protern Clock iOS app | Dish | |
| Description: | iPhone and iPad compatible app that connects to the camera via a 3.5mm audio cable. | Dedicated piece of hardware that can attach to the camera via its shoe attachment and plugs into the 3.5mm microphone input. |
| Best for: | Occasional video use; Testing out enhanced video analysis; Smaller teams with 1 or 2 coaches. | Heavy video use; Larger teams with multiple coaches; Those who want the simplicity of a dedicated device. |
| Where to buy: | App Store, $9.99 | Protern Store, $429.99 |
| Requirements: |
Lightening compatible 3.5mm audio cable, starting at $8.99; or, |
2 AA batteries (Shoe attachment and 3.5mm cable is included with the Dish) |
Analyzing video with data: Protern Video
Protern Video is included for free with Protern and it is streamlined to make it easy to either film from a device or import video from camera and link the video to data.
The program works on iOS (iPhone and iPad), Android (Phones and Tablets), as well as Apple and Windows computers.
Some of the benefits include:
- Automatically detecting which athlete was skiing in video, and linking their data;
- Data analysis that compares the video to the fastest overall run for the day, athlete's fastest run for the day or the fastest for that run number (i.e. Athlete A run 1 vs Athlete B run 1)
- Dynamically switch the data overlays to get different insights
- Alter the playback speed and zoom in to better analyze body position
- Side-by-side video and direct data comparison
- Share Advanced Video files with athletes, parents and fans that includes data overlays

- Download Protern Video for Android
- Download Protern Video for Windows
Alternative to Protern Video: Telemetry Overlay
Prior to Protern Video, Telemetry Overlay was the primary way to merge Protern data with video. It is a powerful program that enables you to build custom overlays using the data downloaded from Protern.
The software itself is available for Mac or PC and can decode the LTC signal to precisely and accurately line up the data with the video.
Where to buy: Free trial; $149 at Telemetry Overlay
How to use: How to automatically merge video and data with Telemetry Overlay
Note for Dartfish Customers: While it is possible to use Dartfish Pro S to merge your data to video using LTC signals, many Dartfish customers will use Telemetry Overlay to merge their video, then import into Dartfish for analysis.
Generally speaking, the process for merging data to video is quicker, easier and results in a nicer looking video when using Telemetry Overlay.
Protern Telemetry Overlay Patterns
The Protern Telemetry Overlay Patterns are different layouts to display your Protern data. It is possible to make your own pattern, but we have made a few different Protern patterns.
You can get them for free on our downloads page.
