I saw the posts about Sony camera footage wrapped in .mxf were getting "unsupported media" errors in AECC 2015. But I though the new 13.5.1 fixed that. I cant roundtrip using aaf from MC, I can't import the .mxfs directly. I tried to export a self-containted QT of my Avid timeline, but AE changes the frame rate of the movie file to 1.427 fps.
I literally can't get any video to work correctly inside of AECC 2015. This all worked gloriously on my old Symphony with CS3.
