If I use "Import" from the main screen, and import DJI video as "DJI Action sensor data", a new session is created, parsing the GPS data from the video. However, I cannot find a way to auto-sync the video to a pre-existing session (which was recorded by Racechrono while connected to a Racebox + OBD2 dongle).
I did notice that the auto imported session imported with the wrong time, as displayed in the 'start' column when looking at laps in the session. The actual time was 12:54, while the DJI-imported video says 13:54.
Perhaps this is the source of the issue syncing to an existing session?
I can provide exports and video if that would help.
