In the Object Mask Tool (Premiere v26), I selected a person in my footage and immediately created the mask; however, I am only getting a white outline with nothing cut out and nothing filled. Please advise.

I’m using Adobe Premiere Pro version 26 and attempting to cut out a person using the Object Mask tool.

I select the Object Mask tool, drag over the person in the Program Monitor, and Premiere correctly detects the subject. The mask then appears under Unassigned Masks.

I drag that mask to Opacity, but instead of isolating the subject, I only see a white outline of the mask on a black background. The person is not cut out and there is no fill applied.

I’ve also tried inverting the mask, but the result is the same—just the white outline with a black background.

So far I haven’t seen other editors reporting this issue with the Object Mask workflow in version 26.

What step might I be missing to properly isolate the subject?
