This page shows you how to blur or pixelate part of a video
image. This technique is normally used to blur a face in order to protect the
subject's personality.
This technique uses two video tracks, and can be used with
any editing purpose which supports multiple tracks/layers. Our example uses
Adobe Premiere.
To start on, place the video clip on the timeline. Make an correct
copy of the clip and place it on a video track openly above the original clip
like so:
From the effects palette, add a blur or pixelate effect to
the top track. Set the amount of blur as desired. The example above uses a Gaussian
blur (Video Effects > Blur & Sharpen > Gaussian Blur) set to 30.
