If I take a video and a photo at the same time (both also have GPS tags in metadata, BTW) and upload them on Google Photos, the video will be wrongly sorted in the album because its creation time is thought to be +2 hours GMT. in Mediainfo.exe the creation date is correct (in UTC) and same as in the EXIF of the photo.
If I convert it with ffmpeg with -map_metadata 0 the problem persists.
Does it makes sense to raise a bug for Google Photos or GoPro or it's something I am doing wrong? (I did a whole lot of research but did not find anyone struggling to find a fix for exactly this issue)
Is there a ffmpeg parameter to shift the creation_time back 2 hours so my album is aligned?
something like this bat file would suffice
c:\gopro\ffmpeg" -i %1 -vcodec copy -acodec copy -metadata creation_time="+02:00:00" "%~n1.remux.mp4
i also found about mp4box but did not find such option in command line / bat file
