Tilt/Shift for video

This is likely going to come across as really random (and probably poorly located too) but here goes.

I just saw an ad on TV for a small, local (well, regional, I guess) used-car warehouse. Towards the end they had a slightly elevated (video) shot of part of the lot, with a couple rows of cars visible.

To begin with, the front row of cars was in focus, with the very "modelly" look that one can acheive with a Tilt(/Shift) lens or some Photshopping. Then the focus shifted, and displayed the same effect on the back row of cars.

So, the question is... Do people make tilt-shift lenses for video cameras (whatever kind of camera would be used for filming an advert for a not-huge company), or do video cameras have such wide apertures that such a narrow-DOF effect can be achieved even at a range that must've been somewhere around 7~8 car lengths?

Cheers

Hi Rawlings,

I think I can help you out.
There are 2 ways to achieve your desired effect.
1) In camera effect using DOF. Most times it will work.

2) Post editing effect using a layer mask. This is most prefered because you have the raw file and do what you want with it. If you use in camera DOF you are stuck with exactly what you just shot.
You would use a layer mask and add blur effect, then go into your motion menu and slowly move the blur effect up or down your shot.
Hope this helped.

Thanks
