Different date formats in a single exiftool command

[Athelstan]

In a folder I have JPG and MP4 files.

On my JPG files I want to set the -ReleaseDate tag to the value of the -CreateDate tag

On my MP4 files, I want to set the -ReleaseDate tag to the value of the -CreateDate tag maintaining the date format of the -CreateDate tag whilst also setting the -Year tag to the YEAR value of the -CreateDate tag.

I can do this with 2 commands

exiftool -r -ReleaseDate<CreateDate "C:\Pictures\sample photos"
exiftool -r -d %Y "-year<CreateDate" --ext jpg "C:\Pictures\sample photos"

Is it possible to merge these commands into a single command?

Not with the -ext (-extension) option.  That would have to be removed.

But it really isn't a problem because the Year tag cannot exist in a jpeg so that will be ignored.

To combine them, you would need to use the DateFmt helper function.

exiftool -r "-ReleaseDate<CreateDate" "-year<${CreateDate;DateFmt('%Y')}" "C:\Pictures\sample photos"

This would be the quoting for CMD.  The quoting on PowerShell will be different.
