Your output URLs may contain a couple of wildcards that will be dynamically replaced at runtime. All the attributes must be supplied between {{ }} like the twig variable format. Below is a table of the currently supported properties and some examples.

Option	Description
filename	Replaced with the name of the output file WITHOUT EXTENSION. This is done only on the path of your output URL and executed after all other wild cards
filename_ext	Same as above but the extension of the filename is included
unique	Replaced with a 32 bit, 8char hex string to generate a unique filename
unique_8	Replaced with a 32 bit, 8char hex string to generate a unique filename
unique_16	Replaced with a 64 bit, 16 char hex string
unique_32	Replaced with a 128 bit, 32 char hex string
date	Replaced with todays date in yyyy-mm-dd format. (Job creation time is used)
time	Replaced with the time in hh:ii:ss format. (Job creation time is used)
datetime	A concatenation of the date and time attribute
