New mp4 created at end of each flight

I have a question and hope you can answer it.

The above video was shot during the same flight. The main length of it was when flying with 2 rear green flashing lights but as soon as I saw the green lights start to flash red (flying non fpv) I slowly prepared and returned to base.

I did not trigger return to home and I had full control throughout the landing.

But when I retrieved the video, there is a short second 1:30 sec file of the period of flight after red lights appeared.

I then did another flight today & the same thing happened.

Has anyone else experienced this ? Is this normal behaviour? I looked in the gopro settings and cannot see any time settings.

Thanks

What length is the main file?
A lot of action cams make manageable clips of a set lengh e.g. 10 minutes, but not sure about your camera.
You don't normally lose any footage but the join may overlap very slightly.

Its a gopro black 3+ and the first file is usually between 11 - 12 mins & 2.5gb
