Can you link a geo-referenced video with a indoor course ride?

Say I have ridden a particular route (e.g. the IM70.3 Port Macquarie bike course) and have then saved that route to my Garmin Edge 530 so that I can then play it back indoors on my trainer with ERG mode enabled.

Then say I recorded video of this route while riding it using a GoPro or similar, which will have georeference metadata (am not sure whether this is just for the starting point of the vid or if this is actively recorded throughout the ride - reckon it may be the former... but lets be optimistic)

Are you aware of a way that I could link my riding of the route on the trainer using the Edge530 with the video footage I took??

Cheers, Mark
