Sometimes when sharing videos on YouTube or anywhere else for that matter we find ourselves in need of a quick and simple way how to blur and pixelize personal info shown in the video. It can be anything, faces, license plate on a car or maybe just an annoying logo from another video that you embedded to your video.
In this video tutorial we used Kdenlive and its super useful Auto-mask effect in order to blur a section of the video. Those who are not familiar with Kdenlive, it’s a free video editor, available on pretty much every Linux distribution out there and apparently on Mac and FreeBSD also, something that I wasn’t aware of when making the video.
Blur effect that comes with Kdenlive is specific because it can automatically follow the face of the person whose face you’ve blurred, if you blurred a persons face of course. Watch the video and you’ll see what we’re talking about.
Something that we forgot to mention in the video is that you need to have the Obscure option selected in the effect settings.
This option is selected by default, that’s why it slipped my mind when I was doing the tutorial. If it’s not selected then you’re not gonna see the blur but rather the opposite Denoise, if Denoise option is checked. All in all this is a very simple effect to setup. You can blur videos even if you don’t have a lot of video editing experience.
