When I import files recorded using DJI Osmo Mobile and iPhone 7 plus, I notice that the frame rates of the clips all vary:  29.97; 30; 29.44; 29.60; 29.84, etc.  When recording with Filmic Pro, everything is listed as 30 fps.  Why is the DJI Go app recording at these variable rates.

Any input would be appreciated.
Thanks,
Andrew

Andrewn，you can choose different frame rates in Filmic Pro.  Please check the setting or provide me a screenshot.
Here is the tutorial：
