    I don't think you can have those rates according to the VC-3 specification (SMPTE ST 2019-1 2008).

    The minimum frame size for 720p is 303104 bytes for compression id 1252. The minimum bit rate for 720p59 would therefore be ~145Mbits/sec and 720p50 ~121 Mbits/sec

    More info can be found in avid_mxf_info.c, mxf_avid_labels_and_keys.h and VC3MXFDescriptorHelper.cpp
