I'm working on a project and as an idea involving a dream-like sequence, i'd like a first-person perspective shot of someone falling off a building. It would be from the viewpoint of what the person sees as they're falling (looking down, even though it could be argued a person wouldn't be looking towards the ground while they're falling, i decided it's the way i need it to be shot). My natural inclination is to say 3D is the answer. Maybe with a lot of hard work i could attempt to model a building in Bryce (the only program i have access to right now), but the atmosphere and the rest of the buildings and street and cars etc. is beyond my capabilities. Does anyone have any suggestions about how i can get this shot? It would be about 5-10 seconds in length, with voice-over dialogue. I would need to add in some background sound to make it realistic.

Does anyone have any ideas about how i can accomplish this, or maybe be able to help me with it? I won't need the shot to be finished for awhile yet, i'm just thinking ahead of time. Thanks for any help you can give.

I presume you're not willing to throw your camera off the building but I'm sure you could build a rig, that would consist of a secure holding for the camera, and a number of ropes to guid the camera to the ground... Then you could remove any visible ropes in post. I think that's how I would do it.

The rope idea could work. You could slowly but steadily lower it toward the ground and then speed up the footage in post. That's probably how I would do it too since i'm not too good with 3D.

Good idea potmonkey. You could also start the camera on the ground and pull it up, then reverse the footage. It might be easier to make it smooth that way, instead of having to lower it down. You could atack the rope to a motor of some kind and just pull it up.

Yeah. Pulling it up would be better. Trying to do iy CG would be really hard, take too much time and never look as good.

Wait! No! Pulling it up might not be such a great idea... unless in this dream the people and cars on the streets walk and drive backwards!
Who knows. Maybe it won't be that noticeable.

heh heh. we had a shot in a film where the camera zoomed really quikly into a guy in a shopping centre, then really quickly out again. It was the same piece of footage reverse, and you'd be suprised how few people noticed!
Actually, running backwatrds, it did look a little dreamy.

Or if it's a really big building and you cant do the rope thing. You can just place your camera on a tripod looking straight down from the roof and then just slowly zoom. If you have a remote control for that camera use it to zoom, that will make it smoother.

hmmm.. it seems 3D is out of the picture then... yeah i'll have to try either lowering it or pulling it up, i'm just concerned about how smooth it will be. I really wanted this shot to be intense for the audience. Can Premiere 6 add decent motion blurring to the sped-up footage? (a must to have it look decent)

thanks for the input, guys.

What kind of camera do you have? Some models have a mode called "slow shutter" that will let you film at 15 fps or less, giving a ton of extra motion blur. You'd still need to speed it up in post, though.

5 - 10 secs to cover the dialogue with the speed of the camera increasing exponentially until the camera/body reaches terminal velocity.

That's works out as a pretty big building so dipping the camera off the side of your house aint gonna work.
Ropes off the side of an office building or car park wont work because of the nasty swing you get (even worse with winds)unless you use a solid guide for the camera.
No matter what your 3d skills it shouldn't be too bad to model it well. I'm guessing that a long cg pan would be more effective than a slow motion dip off a 12ft cottage roof and a hell of a lot faster to do than rigging up any high roof shenanigans

The Solution to Your Problem:
Rig yourself a parachute to an old VHS camera that's about to croak anyway (the bad quality will "enhance" the dream feel) and chunk it off a building. Don't forget a guy wire attatched to the back. Maybe foam pad the casing too and have a friend lunge and catch it at the last second. YOU CAN'T LOSE!

Hi,

definately this is the right direction, I mean I do a lot of 3D stuff, but it takes enormous amounts of time...

In After Effects you could speed up the footage using frame-blend and deinterlace to create some kind of motion blur. There's a plugin called twixtor that will give you a lot of flexibility on speed and motionblur.

there are more plugins that will let you add motion blur, I think one's called reelsmart motionblur. Think it's for After Effects though.

maybe you could use on of those carts that window washers use that hang on the side of really large buildings?
