I have been attempting to modify the metadata dates in mp4 files using exiftool. So far, I have only been able to modify the “Date” and “Media created” fields as seen in Windows file explorer. However, when I use Photoshop Elements to organize my pictures and videos, it appears to only recognize the “Date Created” and “Date Modified” fields. Unfortunately, my attempts to modify these fields using the “exiftool “-modifydate” command have been unsuccessful.

After receiving some helpful replies from others, I now understand that Photoshop reads the system dates (Date, amended date, created date), which is why exiftool is unable to modify them. I have found a free tool called Bulk File Changer, which allows me to modify the Created, Modified, and Access dates.

This tool also has an option to read the date from the file names, which works well for me since all my file names begin with the date and time of the original creation. I still need to figure out the UTC issue, but since I live in the UK, the time difference from UTC is not significant for organizing family pictures and videos.
