Ever wish you could acheive a documentary-style face blur in your video projects? DIY video blogger extraordinaire Tinkernut details how to do exactly that with a handful of free software.

The star applicaiton in this process is a free app called Wax, which handles video compositing and some special effects. Tinkernut excellent walkthrough coveres every step in the process.

Apart from blurring the face, the video also covers how to change the voice to give it a little extra anonymity, but be aware: At the very least the voice adjustment is just a pitch change, so it could be reverse engineered easily enough by someone determined to hear the voice. The same may be true for the blur, but we’re not exactly video modulation experts over here. Either way, this isn’t a “hide from the KGB” guide—it’s just a simple and effective method for blurring out faces or other sections of your video.
