hi,
usually the checkerboard comes up, if a codec isnt supported - this seems to be the case here, as the audio does show up, as you say.
im not familar with different prores flavours, but i thought, that all (incl 4:4:4:4) would be supported - can you import other files, like the mxf by drag&drop - or same problem?
or are you on linux?
