The following two example scripts get properties for the frontmost already open movie in QuickTime Player X (the default one in Mac OS X 10.6 and later), and a second version for QuickTime Player 7 (an optional install for 10.6 an later). As you can see they offer different results.
It should be fairly straightforward for you to take these scripts and add extra lines to transfer to values in to FileMaker.
Script 1 - for QuickTime Player X

set mydocument to document 1 -- gets frontmost open movie
set myproperties to properties of mydocument -- gets properties of movie as list
