Photos.app .xmp to movies

[wywh]

macOS 12 Monterey Photos.app 7 exports .mp4, .m4v and .mov movie .xmp sidecars with "Export IPTC as XMP" option as:

I can copy all updated .xmp sidecar Dates, Titles, Descriptions, and Keywords to the original .mp4, .m4v and .mov Keys and set the file dates with the following command so they are shown in QuickTime Player and Photos.app (they prefer Keys:DisplayName over Keys:Title. Keywords are not imported to Photos.app):

exiftool -overwrite_original_in_place -ext mp4 -ext m4v -ext mov -tagsFromFile %d%f.xmp -api QuickTimeUTC=1 '-QuickTime:CreateDate<XMP-photoshop:DateCreated' '-Keys:CreationDate<XMP-photoshop:DateCreated' '-Keys:DisplayName<XMP-dc:Title' '-Keys:Description<XMP-dc:Description' '-Keys:Keywords<XMP-dc:Subject' '-FileCreateDate<XMP-photoshop:DateCreated' '-FileModifyDate<XMP-photoshop:DateCreated' .

AFAIK Apple uses wrong format for the GPS references in .xmp, and the correct way should be:

<exif:GPSLatitude>36,36.36S</exif:GPSLatitude>
<exif:GPSLongitude>66,54.54W</exif:GPSLongitude>

-> Question: how can I bypass this flaw and copy the GPS to movies 'Keys:GPSCoordinates' with the correct references for western and southern hemispheres?

[Keys]          GPSCoordinates                  : 36 deg 36' 36.36" S, 66 deg 54' 54.54" W

p.s. I can successfully bypass the same flaw in .xmp sidecar to .jpg with:

exiftool -overwrite_original_in_place -ext jpg '-IPTC:CodedCharacterSet=UTF8' -tagsFromFile %d%f.xmp -@ xmp2exif.args '-GPS:GPSLatitudeRef<XMP:GPSLatitudeRef' '-GPS:GPSLongitudeRef<XMP:GPSLongitudeRef' -@ xmp2iptc.args '-XMP-photoshop:DateCreated<XMP-photoshop:DateCreated' '-FileCreateDate<XMP-photoshop:DateCreated' '-FileModifyDate<XMP-photoshop:DateCreated' .

...while with correct .xmp GPS references I could simply use:

exiftool -overwrite_original_in_place -ext jpg -tagsFromFile %d%f.xmp -@ xmp2exif.args -@ xmp2iptc.args '-all:all' '-FileCreateDate<XMP-photoshop:DateCreated' '-FileModifyDate<XMP-photoshop:DateCreated' .

[Keys]          GPSCoordinates                  : 36 deg 36' 36.36" S, 66 deg 54' 54.54" W

You would use a variation of this example with a little alteration for GPSCoordinates

'-GPSCoordinates<$xmp:GPSLatitude# $xmp:GPSLatitudeRef $XMP:GPSLongitude# $xmp:GPSLongitudeRef'

Thanks for the hint. I unsuccessfully tried to modify my command with some variations to copy those flawed XMP-exif GPS tags correctly to Keys (which works better than ItemList and UserData):

ls
movie_mp4.mp4   movie_mp4.xmp

exiftool -a -G1 -s movie_mp4.xmp
[ExifTool]      ExifToolVersion                 : 12.34

[XMP-exif]      GPSLatitude                     : 33 deg 27' 6.68" N
[XMP-exif]      GPSLatitudeRef                  : S

exiftool --ext xmp -tagsfromfile %d%f.xmp '-GPSCoordinates<$XMP:GPSLatitude# $XMP:GPSLatitudeRef $XMP:GPSLongitude# $XMP:GPSLongitudeRef' .

exiftool --ext xmp -tagsfromfile %d%f.xmp '-GPSCoordinates<$XMP-exif:GPSLatitude# $XMP-exif:GPSLatitudeRef $XMP-exif:GPSLongitude# $XMP-exif:GPSLongitudeRef' .

Warning: No writable tags set from ./movie_mp4.xmp
    1 directories scanned
    0 image files updated

p.s. A year ago I sent feedback to Apple about this .xmp GPS reference flaw but it is not fixed yet and I am not holding my breath. I just sent another note about this to Apple.

Oops, sorry, forgot that a comma is needed when writing GPSCoordinates
'-GPSCoordinates<$XMP:GPSLatitude# $XMP:GPSLatitudeRef, $XMP:GPSLongitude# $XMP:GPSLongitudeRef'

Thanks! Little things mean a lot.

I can copy all macOS 12 Monterey Photos 7.0 generated .xmp sidecar Dates, GPS, Titles, Descriptions, and Keywords to the original .mp4, .m4v and .mov Keys and also set the file dates with the following command so they are shown in QuickTime Player and Photos.app (they prefer Keys:DisplayName over Keys:Title. Keywords are not imported back to Photos.app, though. Unlike Final Cut Pro, Photos.app does not use Keys:Author so I omitted it here).

I used '-Keys:GPSCoordinates' because '-GPSCoordinates' defaults to ItemList instead Keys (which works better than corresponding ItemList and UserData tags).

exiftool -overwrite_original_in_place -api QuickTimeUTC=1 --ext xmp -tagsFromFile %d%f.xmp -api QuickTimeUTC=1 '-AllDates<XMP-photoshop:DateCreated' '-Track*Date<XMP-photoshop:DateCreated' '-Media*Date<XMP-photoshop:DateCreated' '-Keys:CreationDate<XMP-photoshop:DateCreated' '-Keys:GPSCoordinates<$XMP:GPSLatitude# $XMP:GPSLatitudeRef, $XMP:GPSLongitude# $XMP:GPSLongitudeRef' '-Keys:DisplayName<XMP-dc:Title' '-Keys:Description<XMP-dc:Description' '-Keys:Keywords<XMP-dc:Subject' '-FileCreateDate<XMP-photoshop:DateCreated' '-FileModifyDate<XMP-photoshop:DateCreated' .

That command bypasses the macOS 11-12 Big Sur and Monterey Photos.app 6.0-7.0 .xmp export flaw with GPS references:

<exif:GPSLatitude>36.610100000000003</exif:GPSLatitude>
<exif:GPSLatitudeRef>S</exif:GPSLatitudeRef>
<exif:GPSLongitude>66.915149999999997</exif:GPSLongitude>
<exif:GPSLongitudeRef>W</exif:GPSLongitudeRef>

...which should be:

<exif:GPSLatitude>36,36.36S</exif:GPSLatitude>
<exif:GPSLongitude>66,54.54W</exif:GPSLongitude>

Hello! Your script is just what i was looking for, as im trying to do correct date created from iPhotos.
But scripts return error Warning: Error 256 running "/usr/bin/setfile" to set FileCreateDate

I'm a new one to ExifTool, installed on MacOS 13.4.1, cd to directory where files+xmp are and from there started the script. Any advice or help?

Thanks!

You need to install "setfile" on your MacOS system.  You can do it by typing this command:

xcode-select --install
