Title: Extracting GPS data from .mov
Post by: Petrasio on December 31, 2013, 08:20:09 AM
Recently bought this dash cam LS430W which makes .mov with embeded GPS data and also many other stats. Right now there is only 1 program I found, that can actually EXTRACT something from this .mov (except the original DOD player, who does everything but does not show it to you in a sidecar file). I wont make advert, I only tell that its just russian. Works great when you want to extract embeded GPS from every format and store it on 6 different types of files. Anyway - it does work but export gives you like 100 GPS positions for 3 min. video - which isnt much, and I am sure there are many others between (records are in milliseconds). I want a tool with a function to export GPS data with many, many stored positions, detailed for ... say every second of the length of the video.
Will Exif be able to do that?

Typically GPS receivers only output a new position once per second.  I have noticed that Sony cameras only update once every 2 seconds, so 100 positions from a 180-second video sounds close (I would have guessed 90).

My hope is that I will be able to add this feature to ExifTool in the next release.
