    How to extract geotagged frames from video for use in photogrammetry

    Okay, I solved the latitude/longitude inversion issue: the exiftool has parameters that set which part of the globe you're refering to: -GPSLatitudeRef=N -GPSLongitudeRef=W works for me in the US but you might need -GPSLatitudeRef=S -GPSLongitudeRef=E if you live in Australia as Zee does I'm...

    How to extract geotagged frames from video for use in photogrammetry

    Zee, thanks for your reply! Yes, it seems to be a Windows string thing... Changing -DateTimeOriginal='%s' to -DateTimeOriginal=\"%s\" fixed the date error and changing -ShutterSpeedValue='%s' to -ShutterSpeedValue=\"%s\" fixed two more. Another more problematic issue: the latitude and...

    How to extract geotagged frames from video for use in photogrammetry

    My Controller is Charging My Phone?

    Disconnected?

    Hi, My Mavic Pro RC has a hard time connecting with my Android devices. It seems random when I plug it in whether Android will offer to connect it to the app, and then whether the app (DJI 4+ and Litchi) will show "connected". Is this usual? I wonder if I have a bum controller...?

    My Controller is Charging My Phone?

    Hi, The controller on my Mavic Pro seems to be charging my phone? When I plug it in to my Nexus 7 tablet (micro USB) or my Pixel 2 phone (USB C) the device shows the charging symbol, and the battery on my controller goes down faster than my drone... Is this normal behavior? Is there anything...
