Masking appears broken in my Motion 5
I am dumbfounded. I am a new Motion user and I've gone through tutorials and I am trying to make a mask.. and it seems that while I can make a mask, and in the thumbnail for the clip I am masking, it actually shows that the clip is masked, but in the preview window I just see the mask as the shape outline and that's it.. it isn't masking out the video.
I have looked at 5 youtube videos tutorials in Motion 5 and AS SOON as they make a circle mask immediately BOOM in the preview window the mask shows.
I went through all the preferences thinking that maybe something is set to not show masking in the preview window but I can't find anything.
Please help! Thanks
