I have an Action cam from Garmin with GPS and many more recording Features. At the Moment I got the Information from ZWIFT Team that it is not possible to use this track on ZWIFT Software to drive this track again. It would be fantastic to use such Recordings also for the ZWIFT community in the future.
Modern Video editing Software can erase cars or persons from the Video and transform the original Picture in Computer animated films. So the tracks can look like tracks from ZWIFT.
