This filter allows you to mask people faces (with a fuzzy mosaic) in video interviews.

All you have to do is to specify the mask position, its dimension and its resolution !

Warning For the moment, the fuzzy mosaic application is static.

This means it won't follow the person you want to mask if she/he is carried out moving too much.

So you will have to experience your clipping skills !


Display a short description of the filter and its arguments.
