Filter_facemask Documentation
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 !
