Yes - any VFR clip will import as a 60 fps (or 50 fps for PAL countries) clip, but the framerate will be what is set on the camera. ie, if you shot 18 fps, you'll get an 18 fps cadence within a 60 fps file.
Weird, I have some VFR clips that will not import into PPRO. All other clips that are ot VFR import just fine. I get an error message from PPRO on the VFR clips saying that the file format is not supported or the file is damaged.
