I managed to answer my own question. Relive just appeared one day and apparently I signed up for it somehow in Strava, just don't remember doing it tho.
Anyway.. If you use the strava app to add photos taken during a ride then Strava will link the photo timestamp to the relevant gps coordinates so they appear at the appropriate point in the video.
Just been out to test this and it seems that it's an automatic function in Strava with no other input needed..
