I am running Sony Movie Studio Platinum 12.0. I have put a cookie cutter effect on some clips, with the feather setting on to blur the edges.
The blurring is visible in the Preview window when I am editing. But when I render, the feather effect disappears in the Preview window as it is rendering. When I play the rendered file (mp4) the rendering is also not visible.
I have tried different output formats, but each time the feather effect is not seen.
Is this a bug with v12.0?
