Sometimes for privacy reasons we need to hide the identity of a person in a video. The best way to do it is to blur or pixelize a face of this person.
Today I'm going to tell you how to do it in several simple steps using VSDC Video Editor.
Step 1: Apply Effect (pixelation, Blurring, Noise, Etc)
Add a video to the scene and select “Video Effects” >> “Filters” >> “Pixelize”
Step 2: Place a Mask
Make a double click on a “Pixelize” layer. Add an ellipse and place it on the scene around the face you want to pixelize.
Step 3: Invert a Mask
To apply the effect to the face only, we need to invert the “Mask” tool. Open “Composition mode” tab and select “Yes” in front of “Invert Mask”.
Here we are!
But note, that a pixelized mask will follow a camera focus, and not the object (face) you want to keep hidden. Therefore, if a person moves in your video, he or she will instantly lose the pixelized mask.
And here we should apply movement tool to cover the person's face all video long.
