Ian? Have you done a search here on this Forum for this? If not, I would suggest you give it a go. There is MASSES of info about the aspects of "masking-out" "hiding" "bluring faces" "pixelating" "bezier curves" and "track motion" for "locking" a mask to "movement" - yeah? You might also see links to tutorials on this one.
. .I may have got some of them wrong . . but they will give you a start .. let us know how you get on. Once you've started, you WILL have fun with it - totally WILD!
This gets asked so much that we added it to Ultimate S2. Download the trial, go to the Special FX tab and select COPS and press OK. That’s it. This will copy the selected event to a new track above it, pixelate it and add a cookie cutter circle.
Here is a project file from the VASST site that shows you howt.
It just suddenly struck me that if SONY were to add "bound radius" and "position" parameters to the blur and pixellate effects (these already exist in light rays and radial blur, for example), this effect would be easily acheivable with a single event. There wouldn't be any need for the duplicate track.
Hmmm...unless I am missing something - would it be easier to just add an "invert" option? (And I don't mean the Sony negative/positive 'invert' plug-in - I mean the Photoshop plug-in type "invert' as it relates to the cut away section. Ok, maybe call it "reverse" - I dunno) If you used the radial blur everything now goes "out" from the area selected - if there was a way to just "invert" you could just use that.
