Dear John
Thank you very much for your response. Yes you can ask!
I do need that information, because my Premiere-like application must
inform the user about the framerate of every movie s(he) uses, to be
frame-accurate (30,29.97,25,24, 15 im/sec) when s(he) derushes.
If I can't obtain that, bye-bye my app, it's not serious to let the user
guess the framerate!
May be Bruce Epstein would have the answer but I can't find it in his
marvellous "Lingo in a nutshell".

Your response:
Hallo Jean-Louis,
If you use Quicktime Player to get Info
you must select *Video Track * (by default it is
set to movie) from your options (left hand dropDown
menu) and then you can select FrameRate from the
right hand dropDown menu.
I don't know if you can access this info through
Lingo though!
Can I ask?
Why do you need the frame rate?
AFIK it is not that one can change it on the run!
Oh, well....I hope this helps.
John
