Hello,
Below is an export from ExifTool GUI. I am wondering why there are two tags "ContentCreateDate" there and how do I distinguish them.
I am asking because one of them has always been there (Content Create Date : 2014:02:02 09:34:05-07:00) and it is not visible by any software in Windows
the other one (Content Create Date : 2014:02:02 16:34:46Z) appeared after I corrected date using Windows Live Photo Gallery and it is shown as "Date taken" as well as "Media created" in File Properties in Windows File Explorer. I know that because I put 46 seconds instead of 05 seconds on purpose.
Please let me know if any ideas.

Odd. They are both in the same group. I expected them in different groups.
The only way to distinguish them is by instance number:
exiftool -contentcreatedate FILE
exiftool -copy1:contentcreatedate FILE
Pick the one you like best. I don't know what the difference is.

I see. The top one (2014:02:02 09:34:05-0) which is the real one is -copy1:contentcreatedate. The other one (2014:02:02 16:34:46Z) is -contentcreatedate.
exiftool -api quicktimeutc=1 "-contentcreatedate<copy1:contentcreatedate" FILEgives the error:
Warning: Sorry, contentcreatedate is not writable - FILE
Warning: No writable tags set from FILE
0 image files updated
1 image files unchangedI thought the tag is writable when QuickTimeUTC option set to 1.
ExifTool can not currently write ContentCreateDate. See the QuickTime tags documentation (https://exiftool.org/TagNames/QuickTime.html) for a complete list of tags and which ones are writable.
Write support is currently very limited for MP4 files.

I see. Thank you anyways Phil
If you download any 1080 mp4 file from youtube with JDownloader 2, you will notice that has a field with the year:
Content Create Date : 2018
Any idea how to write that into another mp4 file? Lower resolution mp4 files don't have that tag.
I think it's here, it's located at the very end of the file:
00d197f0: 1ca9 6461 7900 0000 1464 6174 6100 0000 ..day....data...
00d19800: 0100 0000 0032 3031 3800 0000 25a9 746f .....2018...%.to
Recent versions of ExifTool can write this tag.
- Phil
But how do I write only the year,? like the example.
exiftool -ContentCreateDate#=2018 file.mp4
The hashtag is shorthand for the -n (--printConv) option (https://exiftool.org/exiftool_pod.html#n---printConv).
