breaking currentTime into minutes, seconds, and frames

[Josh Mellicker]

FYI, here is the code for displaying the time of a Quicktime movie in  
HH:MM:SS:fractions:

(this is a button script)

ON mouseUp
     IF the paused of player "Player" is false THEN
         stop player "Player"
         set the numberFormat to "##"
         put the currentTime of player "Player" into this_time
         put the timeScale of player "Player" into movie_scale

         put this_time div movie_scale into total_seconds
         put this_time mod movie_scale into partial_seconds
         put total_seconds div 3600 into hours2
         put total_seconds div 3600 into hours1
         put (total_seconds - (hours2 * 3600)) div 60 into minutes1
         put (total_seconds - (minutes1 * 60)) div 1 into seconds1

         put cr & cr & "time: " & hours1 & ":" & minutes1 & ":" &  
seconds1 & "." & partial_seconds & " - " after fld "notes"
         select after text of fld "notes"
         set the label of me to "start movie again"
     ELSE
         set the label of me to "stop movie and take note"
         start player "Player"
     END IF

END mouseUp


This is working great... except for ONE THING (isn't there always  
that ONE THING... ;-)


The fractional seconds (partial_seconds) is coming out as a variable  
digit number:

time: 00:00:01.217 -

time: 00:00:02.367 -

time: 00:00:04.99 -

time: 00:00:05.398 -

time: 00:00:07.08 -

time: 00:00:08.237 -


So finally, my question is:

Is there any way to determine the FRAME RATE of a QT movie?

That way, I could display true frame numbers...

Otherwise, how come, once I set the numberFormat to "##" are those  
numbers coming out 3 digits sometimes?


Thanks,

Josh
