video filter question

Imagine you're looking at a building or people walking by through a stranger's prescription eye glasses and everything seemes a little bit stretched and kind of out of wack.


I keep seeing a similar effect on random television programs and would love to know how it's done.

thanks.
 
You could do it in compositing. Rotoscope out the lens part of the frames so to only affect the lens part of the frame. Then with that mask available you can apply a variety of filters and the like to achieve the effect. Even simple things like just playing with a touch of distort and a light gaussian blur might suffice. Personally I'd prefer to do that kind of thing inside of shake.

In FCP you could still matte out the lenses. Stack a couple of a video layers. Mask out the lenses on the top one. Use some keyframing or such if they're being pulled on or off. Then mess with the distort (Motion tab stuff might do the trick) and blur (filters) settings in FCP. Or you could check out your personal filter set (everyone will have a different variety) and see if you have something else that will better provide the look you wish to achieve.

cheers.
 
thanks for the reply bud.

one more thing.

Imagine a television monitor shaped like a giant basketball playing the same image you would see on your normal television. The image is clear, yet it's stretched and angled.

Any idea what i'm talking about?
 
In FCP, man that would take some work. I guess if its a steady shot, you could work the masks and the distorts really carefully to try and mimic such an effect. I couldn't really imagine it holding up to what I would consider "tolerable" though.

Personally I think the easiest way to do that would be to take the video right into a 3D application and map it right onto a spherical object. Might still require some compositing treatment as well. I don't have those tools here at work so can't even do a test on that I'm afraid. But you're talking full on visual effects realm with that scenario, well beyond just editing.

cheers.
