How to sync with external Hero4 footage
Posted: Sun Dec 27, 2015 4:23 am
(I'm sorry if this is a faq - I have read the documentations and searched the forum.)
I have lap times and also video I recorded separately on a Hero4, and I want to make an overlay. Following the instructions in http://www.gps-laptimer.com/LapTimerDoc ... hapter.pdf I got the video into the right directory where Laptimer could see it, and then I chose to add that to a session.
I got a dialog asking me to choose the last frame of the lap, but this was very difficult. On my Nexus 6 the video and controls are very small and fiddly, so it's hard to advance to just the right frame and I can't really see the start line. But more seriously, I'm not 100% sure if the Laptimer recorded my entry lap as its first lap, so I might be off by a whole lap.
It seems to me that the video should have an embedded time stamp from the camera, as does the lap times. Is there a way to use this to get the alignment at least roughly right to start with?
