I’ve had this problem come up a couple of time with v4, and now it has popped up in v5.02. Seemingly randomly, when I export from Premiere or Media Encoder, the masks are completely ignored when outputting to Apple ProRes and a couple of other codecs. So in my case, I’m using some blur and sometimes a tint in the mask shapes, but when I export, the entire frame is blurry and/or tinted. My first workaround in v4 was to export to Animation codec, then re-export that into ProRes. Didn’t work with v5, but I AM able to export directly to ProRes if I import the Premiere project into AE and export from there. Weird, right?
I realize this may actually be an Adobe or Apple issue, but since I only see it when using Mocha masks, figured I’d put it out there in case there’s a fix.
P.S. Thanks for the webinar Mary (and others that made it happen). Even thought I already own Mocha Pro, I found it educational nonetheless.
