I am new to video and have a question regarding something I saw. http://youtube.com/#/watch?v=NQlueM5ETYU In the sequences where there is blur in parts of the frame, is this done in camera or likely in post. I can see that maybe it is done in camera by things like vaseline on the lens,tilt-shift, or lensbaby type stuff. I wanted an educated opinion because I have pretty much zero knowledge of video post . Thanks
