Recording can't be viewed on Mac?

I’ve tried recording:
ADD 1-5 FILE fulltest.mp4
and ending recording:
REMOVE 1-5 FILE

Got the file on my mac but can’t see anything. Is there another recording format supported by both Caspar and Mac?

I make sense to add a -vcodec option. for instance:

ADD 1 FILE "Output.mov" -vcodec libx264 -preset ultrafast -tune fastdecode

or

ADD 1 FILE "Output.mov" -vcodec dnxhd

You can use the official client to try out different options.
