I am working on a video at the moment, and there is a street address I'm trying to blur out. My friend holding the camera had it moving all over, so I spent a good hour creating keyframes. After finishing, I was shocked to find that most of my keyframes were set to negative, so the area I had gone around with the square box was not blurred. I am praying that there is a way to fix this all at once, so that I don't have to spend another hour fixing this. I saw a forum post a while ago stating that it didn't work, but that was way back in 2009. So, my question is, can I set all of my keyframes at once to positive on Sony Vegas Pro 14?
