Hello,
I try to sync DateTime and DateTimeOrioginal.
exiftool "-Software=" "-GPSAltitude=" -DateTime=DateTimeOriginal *.jpg
exiftool "-Software=" "-GPSAltitude=" -DateTime<DateTimeOriginal *.jpg
exiftool "-Software=" "-GPSAltitude=" "-DateTime<DateTimeOriginal" *.jpg
exiftool "-Software=" "-GPSAltitude=" "-DateTime=DateTimeOriginal" *.jpg
exiftool "-Software=" "-GPSAltitude=" "-xmp:DateTime=DateTimeOriginal" *.jpg
but every command tells me:
Warning: Invalid date/time (use YYYY:mm:dd HH:MM:SS[.ss][+/-HH:MM|Z]) in XMP-tiff:DateTime (PrintConvInv)
0 image files updated
1 image files unchanged
Does anybody know how to write the command?
Thank you
This should work: exiftool "-Software=" "-GPSAltitude=" "-DateTime<DateTimeOriginal" *.jpg (mind the quotes!). Actually better is to use exiftool "-Software=" "-GPSAltitude=" "-DateTime<DateTimeOriginal" -ext JPG instead (see common mistake #2 (https://exiftool.org/mistakes.html#M2)).
It will strip the software and gpsaltitude and set the xmp-tiff:datetime tag to the datetime original.
If this doesn't work, can you show the output of exiftool -G0:1 -DateTimeOriginal for one of those files?
Cheers,
Hayo
Thank you for your help Hayo Baan,
now the command looks fine and there are no errors :D
I tried the command 'exiftool -G0:1 -DateTimeOriginal xxx.jpg' bevore any cahnges
[EXIF:ExifIFD] Date/Time Original : 2017:08:21 08:54:46
also tried 'exiftool -G0:1 -DateTime xxx.jpg'
there is no output
but in irfanview I see a DateTime and DateTimeOriginal in exif and that is not sync.
now I execute 'exiftool "-Software=" "-GPSAltitude=" "-DateTime<DateTimeOriginal" *.jpg'
no errors.
then again 'exiftool -G0:1 -DateTimeOriginal xxx.jpg' after sync.
[EXIF:ExifIFD] Date/Time Original : 2017:08:21 08:54:46
and also 'exiftool -G0:1 -DateTime xxx.jpg'
[XMP:XMP-tiff] Date/Time Modified : 2017:08:21 08:54:46
( same date as DateTimeOriginal)
but when I open the new synced Image with IrfanView and open the Exif viewer DateTime and DateTimeOriginal are not sync.
Is this an IrfanView error?
Could be, but perhaps irfanview simply uses a different tag? (actually, this is very likely since the tag DateTime did not exist before your changes).
Run exiftool -G0:1 -time:all on a file to see all time fields that are present in the file and then search for the one you need to change.
Thank You,
now I have the command that changes the DateTime and also the modify date:
exiftool "-Software=" "-GPSAltitude=" "-ModifyDate<DateTimeOriginal" "-filemodifydate<DateTimeOriginal" *.jpg
now also the Date is correct shown in IrfanView and also in Windows Explorer - Date modified looks fine.
Thank you for the great and quick help
