As I understand it iDevices don't guarantee any particular frame rate... it depends upon conditions, and up to some maximum frame rate depending upon the device and generation.

Depending upon how Premiere is handling them you might want to run them through AE first to standardize the clip frame rate to your project frame rate.

Two clips are coming in at 24fps and two are coming in 30fps. Mediainfo shows them at 24.06 and 28.86.

What is the default frame rate of the ipad? The only thing I could find online is that you can change it up to 30, but I don't know if this is default.  They don't = even know how to change the settings.

Thanks,
