Rename images and videos at once (single rename run)

Rename script for renaming images and videos at once (one run) with advanced settings.

I have several devices being able to capture images and videos (camera, smartphone...) and I want them to name them by "year-month-date time" so that i can sort them by capturing time without having to look into metadata (this a very slow process compared to sort by name). It is using leading 0 since without the sort order will go crazy (10-19 comes between 1 and 2).
Because the time the media was captured is saved in different metadata fields depending on the media/metadata type, a general renaming approach/command is not able to do this.
So this script extracts the corresponding metadata field and formats the date regarding the pattern.
If no metadata field is found you can enable a fallback date (date the file was created which works as long as the file was untouched on the device it was created at).
You can also perform a regex check so that renaming only is done when the name does not match the pattern (honestly not sure if neccessary or the saved time - if at all - worth the effort; but you can).

Regex explanation
For those of you who are not familiar with regular expressions (in this script used to check wether to rename if name does not match the regex pattern), no worries: ill explain it shortly (in case you want to change the pattern / date time format).
I know it looks horrible

([12]\d{3})-(0[1-9]|1[0-2])-(0[1-9]|[12]\d|3[01]) (?:[01]\d|2[0123])-(?:[012345]\d)-(?:[012345]\d)

but its easy

  • ([12]\d{3}) means a 4 digit starting with either 1 or 2 followed by 3 digits stands for the year (either from the last or the current millennial; 1000-2999)
  • (0[1-9]|1[0-2]) stands for the month, either with a leading 0 or the months 10, 11 or 12 (01 - 12)
  • (0[1-9]|[12]\d|3[01]) stands for the days, either with leading 0 or the the two digit days till 31 (01-31)
  • (?:[01]\d|2[0123]) for the hours with leading (00-23)
  • (?:[012345]\d) for the minuts/seconds (00 - 59)
  • the - is the seperator between the parts of the date / time

	//     e.g., item.name_stem, item.ext,
	//          item.is_dir, item.size, item.modify,
	//          item.metadata, etc.
	//     item.path is the path to the parent folder.
	//     item.realpath is the full path to the file, including its name,
	//          and with things like Collections and Libraries resolved to
	//          the real directories that they point to.
	// - getNewNameData.oldname_field:
	// - getNewNameData.newname_field:
	//     Content of the "Old Name" and "New Name" fields in the Rename dialog.

	// - getNewNameData.newname_stem and newname_stem_m:
	// - getNewNameData.newname_ext  and newname_ext_m:
	//     The proposed new name for the item, based on the non-script
	//     aspects of the Rename dialog. Scripts should usually work from this
	//     rather than, so that they add to the dialog's changes.
	//     newname_ext is the file extension, or an empty string if none.
	//     newname_stem is everything before the file extension.
	//     The *_m versions handle multi-part extensions like ".part1.rar".
	// - getNewNameData.custom:
	//     Contains any custom field values for additional user input.
	// Return values:
	// - return true:
	//     Prevents rename.
	//     The proposed getNewNameData.newname is not used.

	//     Allows rename.
	//     The proposed getNewNameData.newname is used as-is.

	//     Allows rename.
