I recently came across an issue with the GPS coordinates of my videos in Lightroom Classic 10.3.
I have my camera paired with my smartphone so that all my photos and videos have GPS coordinates.
For my photos, Lightroom Classic works exactly as expected. The coordinates are correctly read from the EXIF data and I can see on the map more or less exactly where each shot was taken.
It's a different story with videos, however. I just recently imported a batch of 9 videos. When I opened the map module, all 9 videos were in exactly the same location. (This location was not on my route but it wasn't too far away either - about 50 KM from where I was walking. But it's somewhere I've never been before.)
Investigating further, I opened some of the video files in EXIF tool to check the GPS coordinates. Each of the nine videos in fact had unique coordinates and, after double-checking in Google Earth, I found that these coordinates were accurate. This leads me to believe that this is an issue with Lightroom Classic reading the GPS coordinates from the EXIF data. Furthermore, I also noticed that the seemingly random location Lightroom assigned to my videos was in a different format to the one normally used by the camera.
I have not experienced any such issues with photos. Lightroom seems to correctly read the coordinates for the photos. Even when importing a batch of both photos and videos, the photos have the correct GPS coordinates while the videos are grouped together somewhere random. This is all using the same camera (Fuji XT4).
I've already posted about this issue in this thread, where another forum member was able to corroborate my findings. This indeed seems to be a Lightroom bug.
You can find a sample video here to help you re-create the bug.
Please let me know if I can provide any further information.
