Deleting instances of userdata DateTimeOriginal in video files (copy5, copy6...)

[peho]

I've accidentally adding DateTimeOriginal to video files.
Whenever I try to change the value, a new one is added. (I really don't understand this)
When I search for help, the only I can find is to delete through Perl, but is it possible to do with ExifTool  app?

[QuickTime:UserData:Time:Main:Copy1] DateTimeOriginal: 2019:05:10 12:16:34
[QuickTime:UserData:Time:Main:Copy2] DateTimeOriginal: 2019:05:10 12:16:34
[QuickTime:UserData:Time:Main:Copy3] DateTimeOriginal: 2019:05:10 12:16:34
[QuickTime:UserData:Time:Main:Copy4] DateTimeOriginal: 2019:05:10 12:16:34+01:00
[QuickTime:UserData:Time:Main:Copy5] DateTimeOriginal: 2019:01:01 00:00:00
[QuickTime:UserData:Time:Main:Copy6] DateTimeOriginal: 2019:01:02 00:00:00
[QuickTime:UserData:Time:Main:Copy7] DateTimeOriginal: 2019:01:02 00:00:00

Was it ExifTool that added the copies?  If so, what version?  This should not happen.

You should be able to delete them with this command:

exiftool -datetimeoriginal= FILE

But it would be informative to see the output of exifool -v from this file to see if the UserData is also duplicated.

Ooops.  Yes.  ExifTool is doing this.  I will fix this ASAP.

Edit:  I've found the problem.  It wasn't discovered earlier because it affected only some UserData tags (and apparently not the ones I tested).   I will have this fixed and a new version will be released within a couple of hours.

This bug has been fixed, and ExifTool 11.48 is now available.

With this version, the duplicate copies of UserData:DateTimeOriginal will be deleted when you write it again.

Thanks for reporting this.  I've moved this thread to the Bug Report section of the forum.

That was fast moving
Thank you for looking into this so fast.
Then there was a good reason that I didn't understand it.
Tested and everything is working as expected now.
Thanks again.
