In synchronizing a GPS and digital camera before going out to the field, I do
this manually. I set the time of the camera as sync as possible with the GPS.
Probably it might be the same process for video cameras. Video mapping might
require a more perfect timing because since you are moving relatively fast, a
difference in time between the two hardware could result to a mismatch of GPS
coordinate and the captured video.

That is interesting. I'd probably seen that GPSbabel could export in SRT
format, but it didn't occur to me that this was subtitles as it was out of
context. Question: how do you get the timing of the video and GPX to
sychronise? For a start you'd have to make sure the video recording device and
the gpx recording device had their time set the same. Do you sync them up just
by switching them on at the same time, or is there a way to embed the time in
the video? GPX has time information included of course.
