FileMaker Custom Function: Frames_To_Timecode

I could have used this a few years back when I worked with an advertising research firm:

Description:

Converts film and tv timecode strings eg 01:05:20;02 @ 29.97 fps into a framecount in this case 117484

The calculation traps for the special case of drop frame 29.97 timecode and allows for all other interger fps values.

via FileMaker Custom Function:Frames_To_Timecode ( frames ; fps ).
