visual edit within an already created mask

[MK270100149tqs]

What if i have already created a plain mask around my subject, and then want to add a visual effect within the already created mask? Is there a way to apply a visual effect within that already detirmined mask or do I have to apply the effect then create a mask from that only?

What visual effect do you want to add.

A screenshot might help

If I understand your question, you simply apply the effect to the clip, and that will effect the entire clip, but will only be showing within your mask area.

No Effect with mask:

Same mask, dropped Posterize onto the clip:

You can copy-paste masks between opacity or effects to restrict an effect to an already drawn mask.
