I'm just beginning a project shot on XDCam, which I'm new to. I'm told it was shot @ 1080p 50 Mb/s. In my bins the footage shows this info (and HD422) but also says the Data Rate is 7.1 MB/s. That seems low to me since SD DV is 3.6 MB/s. Was this footage imported incorrectly before it was sent to me? I have XDCam Transfer, but my DP did the transfer.
