Hi @arlie14, and welcome to our forum!
If I get this right, you’ve checked the Photo Gallery of your iPhone, and there’s no trace of the exported file, correct?
Do you, by any chance, see an Albums section there, as well? There should be a Videos tab there, where you may be able to locate your video file.
Let me know what you find.
Hey @arlie14, how are you?
Can you open your Photos app, then go to 'My albums' and check the 'Recents' one, to see if the video was saved there?
Hi @arlie14, sorry to jump in here.
Have you checked, to make sure your iPhone has enough space in order to export the file? Also, if I were you, I'd try rebooting the device and then repeat the export process once again.
Let me know the results.
