Question: Photos app in High Sierra producing unreadable movie files
I recently purchased an iPhone 7 an am running iOS 11.11.1. The original movie files it produces are not being recognised as importable by either FCPX or Quicktime 7 . My normal workflow in FCPX starts with copying the movie files from Photos master files,"Show PAkage contents" putting them in a separate folder, then importing them to FCPX. The Import Media window on FCPX shows the movie, but only as greyed out. When I try to open the movie in Quicktime 7 for a quick overview I receive a "file format not recognised " type error message, a suggestion to take me to a page that might permit importing this file format - but the page on Apple's site is not found.
If I export the movie in photos - to an m4v format, there is no problem opening it in either program.
Anyone have any thoughts? I have been using an iPhone 4s for almost 8 years and have never had any problems using/seeing the movies it creates and stores in Photos
