Cheap or free way to blur out a face?

okc_smoker · 6th April 2010, 17:33

I did a search and, much to my surprise, couldn't find much info on this. I'm looking for a way to pixelate/blur a face in a DV clip. I'm fairly familiar with with VirtualDubMod and AVISynth and I have access to Ulead VideoStudio (I think v8... I'm not at home right now).

Will any of these be able to accomplish this? If not, any suggestions on free or cheap software (< $50) that can do this?

Thanks!

anything that supports using a mask can do it. probably more difficult in avisynth if the person is moving as opposed to something like after effects which can interpolate frames+click and drag the mask.

The basic idea is to use a strong blur, and apply a mask of the blur to only the part of the video that you want blurred.

another free approach might be to decompress to images (e.g. png) then use a free image editor (e.g. irfanview) to apply mosaic or blur to area , then re-assemble the video with avisynth (e.g. imagesource() ) , vdub, or avidemux
