Why do I not see the mask options in Opacity like the square or circle

Like all other professional graphics/video software, they are constantly modifying to keep up with changing hardware/media and effects desires and needs. ALL pro software is handled the same way.

Yes, some things are really unsettling to experienced users at first when they change. Same for me, of course.

But this change is freaking awesome in new capabilities in Premiere ... I’ve done things I wouldn’t have even tried unless I really needed to, because I’ve never been that great at running rotoscoping in AfterEffects. That is essentially done now within Premiere.

Thanks Ann
