Hi all,
I use this command to set all dates by the "OldestDate" custom Tag:
exiftool -m -overwrite_original_in_place -wm w -api RequestAll=2 "-DateTimeOriginal<OldestDateTime" "-AllDates<OldestDateTime" "-DateCreated<OldestDateTime" "-FileCreateDate<OldestDateTime" "-FileModifyDate<OldestDateTime" -r "%ddir%"
exiftool -ext mp4 -ext mov -m -overwrite_original_in_place -wm w -api QuickTimeUTC=1 -api RequestAll=2 "-creation_time<OldestDateTime" "-AllDates<OldestDateTime" "-Track*Date<OldestDateTime" "-Media*Date<OldestDateTime" "-Keys:CreationDate<OldestDateTime" "-FileCreateDate<OldestDateTime" "-FileModifyDate<OldestDateTime" -r "%ddir%"
With UserDefined Composite Tag from here https://exiftool.org/forum/index.php?topic=7986.msg80801#msg80801 (https://exiftool.org/forum/index.php?topic=7986.msg80801#msg80801). I thought this way, I would really update ALL available dates tags. But it seems not so.
After running through the process, my file of concern shows the following output for AllDates:
exiftool -a -G1 -s -AllDates "%~1"->
[UserData] DateTimeOriginal : 2011:09:21 12:02:44+02:00

Looks synchronized. But in MediaPlayer Classic it shows yet another date:

This leads to a wrong sorting in Google Photos which recognizes the date as 2016...
Damn - how to cope with this additionally?
What is the output of this command for that file?:

After running through the process, my file of concern shows the following output for AllDates:
As you've seen,
AllDates is a Shortcut tags (https://exiftool.org/TagNames/Shortcuts.html) for the three most common EXIF timestamps,
CreateDate,
DateTimeOriginal, and
ModifyDate, but it will also write to tags with the same name in other groups.

It shows a lot more times/dates, but still not the one listed as MediaInfo -> "creation_time":
(https://i.imgur.com/lL51K8Z.png)
Can you share the file?
I installed MPC and have looked through several files but couldn't find this entry on any of them. Also, what version/fork are you using?
Alright, I'll send you a link via PM :)
My versions are:
MPC-HC (64-bit)

Actually I do find these entries in a hell lot of mp4 files of mine.
Hmmm, very interesting.
That file has a tag called Keys:CreationTime, which exiftool doesn't know about, so it's not marked as a time based tag. I've passed the link on to Phil so he can take a look at it.
Do you know what program created this file?
Alright, thanks for digging into it.
I dont know how it was created, but I checked - I have a HUGE number of files with that tag it seems... regular videos from smartphone.
I mean you two are seriously into EXIF tags - if you've not yet come across it, I would assume this tag actually should not have a big relevance - is it? Because if so, I'll just add a removal of that tag to my workflow of processing my files. I want to avoid confusion within files at all cost, so getting rid of a unused tag which shows a different date.
----------
I think I found it:
I process my files using ShutterEncoder while preserving Metadata.
I just recorded a video on my smartphone and checked before and after Encoding with Shutter Encoder.
This is what MediaInfo shows:

In this case, obviously the newly created key has nearly the same date (because I just captured and encoded right after each other).
But yes, this could lead to deviation in the future, e.g. if one decides to encode old videos...

Hmmm, interesting.
Or just remove this newly created Key afterwards using Exiftool? But the way I read it is: It still is a difference, right?

Damn, I just wanted to clean it up - because why keep an information which seamingly is nowhere used...
So I wanted to only Focus on the relevant entries.
But you are right, I can't remove this one alone.
Tried several commands:
exiftool -overwrite_original -Keys:CreationTime= output.mp4
exiftool -overwrite_original "-Keys:CreationTime=" output.mp4
exiftool -overwrite_original "-CreationTime=" output.mp4
Nothing worked to remove it. And yes obviously dont wanna use Keys:All.
Thanks all. I'll add support for this tag in version 12.74 (to be released within a few days) so you can edit/delete it as you please. Also so it will show up in the Time group.

Wow thats great to hear. Thanks so much for your amazing efforts :)
I saw it's released! Thanks! Works as expected
