AppleScript for Importing QuickTime Metadata

I am trying to figure out how to write a FileMaker script, using AppleScript, that will allow me to select a folder full of QuickTime video clips and import the following from each clip:
Clip Length (duration in hours, minutes, seconds, etc, such as “00:00:08.67”)
Frame Rate (in frames per second, such as “23.98”)
Frame Size (such as “1920x1080”)

This metadata would need to be imported into each correct record in FM that matches the Filename. Can anyone please point me in the right direction?
