Title: Warning: Tag 'Nikon:CreateDate' does not exist
Post by: spanocchio on April 13, 2016, 10:13:12 AM

Hi all,

I'm new using exiftool and I need to edit some values on a .mov file.
In particular when I try to edit the Nikon:DateTimeOriginal and Nikon:CreateDate return a Warning.


vspa@vspa-PC:~/test$ exiftool -Nikon:DateTimeOriginal="2007:02:18 09:07:22" -Nikon:CreateDate="2007:02:18 09:07:22"  DSC_0221-1_test.mov
Warning: Tag 'Nikon:DateTimeOriginal' does not exist
Warning: Tag 'Nikon:CreateDate' does not exist
Nothing to do.



I don't understand why if I would like to read that value there is any problem.


vspa@vspa-PC:~/test$ exiftool -Nikon:DateTimeOriginal DSC_0221-1_test.mov
Date/Time Original              : 2015:11:01 18:07:01

[XMP-xmp]       ModifyDate                      : 2007:02:18 09:07:22




Also it seems to be a problem with al the Nikon attributes.


vspa@vspa-PC:~/test$ exiftool -Nikon:Model="NIKOND3300" DSC_0221-1_test.mov
Warning: Tag 'Nikon:Model' does not exist
Nothing to do.



Thank you in advance

ExifTool has only limited write ability for video files.  It can't currently write any of the Nikon tags in these files.

The problem is that exiftool (at the moment at least) does not support writing to the makernotes in .mov files :(

I have written a little script that does enable one to update the datetime contained within .mov files. Have a look at this discussion (https://exiftool.org/forum/index.php/topic,6938.0.html) to find it (and see if it may fit your need). Note that the discussion is about .mts video files, the script, however, supports (Nikon) mov files too.

Hope this helps,
Hayo

P.S. Here's a direct link to the post with the script (saves you having to read the whole discussion): post with script (https://exiftool.org/forum/index.php/topic,6938.msg35046.html#msg35046)
