I need to convert a number of movies that I have stored in the Photos app on my mac (OSX 10.13, high sierra).
So, I export the movies from Photos, then convert them using ffmpeg, then import them back into Photos.
This is the ffmpeg command I use (version is attached below):
/usr/local/bin/ffmpeg -loglevel error -hide_banner -nostats -nostdin -i MIRU.mp4 -map 0 -c:s copy -map_metadata 0 -map_metadata:s:v 0:s:v -map_metadata:s:a 0:s:a -c:a aac -b:a 128k -f mp4 -codec:v hevc -tag:v hvc1 -preset faster -crf 25 -x265-params profile=main:me=umh:subme=5:ref=4:aq-mode=2:aq-strength=1.0:psy-rd=2.0:psy-rdoq=1.0:rd=6 MIRU.h265.mp4
Problem is: after importing the new movie into Photos, all meta info is gone, especially the GPS location, date of recording, etc.
I tried to display the tags for both files using exiftool, and from that output it looks like all metadata has been copied over all right.
Except that those data does not contain the desired information.
(Below you'll find the output of exiftool)
I have also tried 'exiftool -tagsFromFile MIRU.mp4 MIRU.h265.mp4' , to no avail.
Does anyone have an idea , how I can transfer all the metadata from the originals to the converted movie files?
Especially date of recording, GPS, camera info.
Thanks a lot in advance for all kinds of insights and hints.
Best regards, Gabriel
