Introduction

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 !

Parameters

help Short help: Display a short description of the filter and its arguments.

xpos X position (0-oo) [0]: The X position of the upper left corner of the mask.

ypos Y position (0-oo) [0]: The Y position of the upper left corner of the mask.

xresolution X resolution (1-oo) [1]: The X resolution of the mask (width of a mosaic pixel).

yresolution Y resolution (1-oo) [1]: The Y resolution of the mask (height of a mosaic pixel).

xdim Width of mask (1-oo) [1]: Width of the mask (= n*$XRESOLUTION)

ydim Height of mask (1-oo) [1]: Height of the mask (= m*$YRESOLUTION)

Usage Examples

Masks a people face with a mosaic at the proper position :

 $ transcode ... -J facemask=xpos:140:ypos:50:xresolution:10:yresolution:10:xdim:120:ydim:140

which actually gives :
