How do you blur out a face?

[thebiginch]

I'm using Serif Movie Plus and have not figured it out. Any suggestions?

Post #2 says: Use Quickshape Ellipse to create a mask. Add keyframes if the subject is in motion.

Post #4 has these step by step instructions for if the face stays in approximately the same place on the screen:

1. Create a mask with the white part -- i.e. the transparent part in Mask track mode -- covering more or less the region of the face movement. In the illustration attached, you will see that the white part covers the region in which the faces of the man and the young woman will move as they talk or look.

2. Place this mask in the top video track, and set the track to mask mode.

3. Place the video clip in the second video track. Apply a blur effect -- e.g. Mosaic -- to the whole clip.

4. Move this track with blurred video clip into a Video Group, together with the mask, which serves as its overlay.

5. Place the same video video clip, unblurred, in a third video track, with the Video Group overlaying it.

You should now have the face or faces in the video clip blurred as the movie is played.

I found that MoviePlus X5 would not do this job successfully unless I worked in a certain sequence from the top down, i.e. first drag the mask to the top track and transform it if necessary, then drag the video clip to be blurred to the second track, etc. I also had to experiment when to insert the Video Group to get the transparency to work as it should.

And lastly this short video clip apparently shows you how, though I didn't watch the whole thing myself: http://www.youtube.com/watch?v=TwF6r2UfewE
