With GoPro action cams, GPS and other metadata are recorded
and embedded in the resulting MP4 files. A few years ago,
GoPro added the ability to add this telemetric data to its edit-
ing app in the form of gauges that you can choose to show
as overlays on the resulting movie, but you can’t extract the
metadata and use it as you wish from within their app. Unless
you buy software like GoPro Telemetry Extractor Premium,
which allows you to do pretty much anything you want with
a HERO’s metadata.
The GoPro Telemetry Extractor Premium app extracts all of
the metadata that’s available with any current GoPro model,
including sensor, GPS, and other data the camera generates.
It allows you to extract data from multiple cameras simulta-
neously; merges the data when it’s appropriate, for example,
when GoPro splits up very long videos into multiple files; and
optimizes it for the output file format you desire. It outputs to
After Effects (mgJSON), GPX, CSV, JSON, KML, and GeoJSON.
The GoPro Telemetry Extractor Premium app is very simple
to operate. You drag a file to the app, click on one of the data
categories, and choose the output format. There’s a dazzling
array of categories, including GPS, Accelerometer, Gyroscope,
Exposure Time, ISO, etc., etc.
You can filter data on frequency, time, smoothing, altitude,
etc. Frequency, for example, lets you create a data point per
frame. If you want to view the data, that’s possible too, either
in graph format or map view (for GPS). Most graphs offer On/
Off switches for specific data on any axis and the ability to save
it as a PNG image.
The GPS view offers a video of your trajectory overlaid on a
white background, satellite, or map view. nCompany: App Prototyping BarcelonaPrice: $299Rating:Hot: Simple interface; extracts all sensor data;
