Retrieving location information from a video with no initial data on my iPhone Photos app

No. ...except if the movie was sent to you and the location was stripped off in transit -- then you might see the location in the original.

I usually check the movie or image location data with a exiftool command like:

exiftool -a -G1 -s -n -ee -Location:All movie.mov

or:

exiftool -a -G1 -s -n -ee '-*GPS*' movie.mov

BTW this does not apply to your situation, but dashcam GPS data is a wild west since many vendors scramble location data in a proprietary way. exiftool developer has reverse engineered numerous such formats.

Right-- how did you get this video? As Matti Haveri suggested, it doesn't look like it came straight from your own phone-- the filename indicates that it didn't transfer in a normal way. You need to go back to the original video if you can.

Huh? I think Matti's suggestion to find the original file is appropriate. The file came from an iPhone 15, apparently, so the original probably had location information that might still be available.

It is not possible to retrieve something that never existed.
