Exiftool creating insanely large GPX files

[br_archimedes]

New to this, so Hi everyone!

I am trying to extract GPS data from a Insta360 Titan video file, so far without any luck.
My aim is to extract the data, fix the very inaccurate GPS path by matching the timestamps of the GPS path recorded by the Titan with that of a CSV file I recorded on my phone (path is way better).

Anyway, I have a 500MB movie file, which holds the GPS data. I ran the following command:

Code Select Expand

exiftool.exe -api largefilesupport -ee -p gpx.fmt test.mp4 > out.gpx
This resulted in a 59GB (!) gpx file. What am I doing wrong here?

What did the output GPX look like?
