Thank you, Tim!

I found also two at graphics magick:


It quite interessting: sometime the first (dpx:mp.frame.rate
), sometime the second (tv.temporal.sampling.rate
) has a useable value.

I made different tests.
For example AFTER EFFECTS and ARRISCAN Filmscanner always writes into "tv.temporal.sampling.rate".
AJA Capturing cards write into "dpx:mp.frame.rate" (e.g. 25), into "tv.temporal.sampling.rate" they write "4.60285e-041".

Best Regards
