Any cyclists here? Strava based question around using power data from a ride in video overlays

Hi All,

It's been many years since I have been here!

So, when I ride my bike I want to be able to extract power data from the ride and overlay this data on videos I record on my GoPro. Here are the issues:

* The ride data includes power data from my power meter
* When exporting data, it is a GPX file, saple below
* As you can see from the xml in the GPX file, the power data has been stripped
* If I export a TCX file this is richer and includes power data, see below GPX file
* The problem is that I cannot use the TCX file to overlay data onto video in the Garmin VIRB video editing software as it only allows GPX files
* So, what I want is to introduce the power data into the GPX file somehow, maybe through a transformation using a different schema
* As a pointer I found this XSD file named in the TCX file that does include power data in:


So could the issue be that Garmin needs to get involved to create the new schema that allows a conversion of the <Watts> tag into <ns3:power> in a new version of GPX extension?

Do techie cyclists with Garmin action cams have the same issue as GoPro 5 people?

Thanks for your help!
