Hang on, there looks like there is a bug - but it still might be Ok.
When I set up a 60p project (with a photo) and try to make a BR image, the preset says it 24p. If I go into the advanced settings and change it to 60p and come back it still says 24p. When I make an image and then inspect the Stream folder, the M2TS file is 60p (59.94 proogressive)#
So the messages are wrong, but the output looks OK.
I'm told there should be a trial version available in the not too distant future, if you don't want to upload some 60p footage.
