I am a new user of VideoStudio X2 and I am experimenting with making a short video tour of the military base where I work in Iraq. There is one small object that I need to blur out of the picture that appears in about 3-4 seconds of the video; I need to cover it with a blur blob, like you would do to someone's face on television if you wanted to obscure their identity.

I am using VideoStudio X2 and I have no sophistication with it or with video editing generally.

Any suggestions?
