model planes on greenscreen

[Alejandro Torres]

Why dont you try to keep the plane static and get some background moving footage that would give you that realistic effect you are looking for. And maybe you could try different angles to give the shot more movement. Or, if you want the plane to approach the camera or something you could just take the static shot and enlarge it or play around with the 3D space of AE.

Hoi,

I had something semilar a while a go(only i was not running from it).
To make things simple:
just use a still of the plane in front view and make the movement yourself in after effects just using scale and the wiggler and use some motion blur. You wont have realy a 3d plane, but iff it go’s fast and you are running from it, nobody will run away from the effect..

Peace

I suggest you don’t move the plane but rather move the camera. I’ve seen it done like that many a time with some pretty great results. Mad TV had a skit where there were a bunch of people in a car driving and the camara would sway back and forth facing the front of the car. When the car pulled over they would just rotate the camara around the car and come to a stop looking through the side door. It looked really damn good. I’m pretty sure that’s what they did for StarWars as well.

Yeah for Star Wars, ILM would often park the model on blue dowels and move the motion control by it, not the other way around. Star Trek movies as well.

As far as motion, ILM had a math formula they would use when shooting models. I didn’t see it offhand in a quick Google search but it’s in one of their books on the history of ILM.

But basically you find the relationship with the scale of the model with the scale it’s real size counterpart, then overcrank your camera when shooting to a framerate based on that difference. This way the slowness creates the illusion of mass. Like in Temple of Doom when the water tower fell over to flood the mine, it was only a couple of feet tall and with a certain overcrank speed it fell and the water moved as though the mass were that of it’s full size counterpart.

But alas, I agree to do it in 3D.

No dude, it may be harder than I think since I’m not actually doing it but it should look pretty nice. You don’t need to run over from the other side of the room. Just a couple feet away to a close up should suffice assuming your model is small enough. A simple swing of the arm can to be use to make it look like your plain came from over head and is diving down decending down on you. Or make a make shift dolly with a tripod if ya want to do a more head on aproach. (An office chair and a tripod on a smooth surface should work)

As the post said below mine, slow the footage down to create the illusion of mass. I don’t recall specific names but I know there are plugins that allow you to slow down footage and it fills in the extra frames to make very smooth movements no matter how much you slow it down.

You’re not exactly trying to recreate a starwars battle here. This is certainly what I would try… in fact I think I will.

Twixtor.
But there is a limit to how much it can create between frames, depending on how much the footage changes between frames. If you really want to slow something down, try cutting it down to half speed, then half again, then so on.

Correction, HE’S not trying to recreate a starwars battle.

All and all the steadyshot on a mini dv should really help in creating a smooth movement and slowing down the footage is a vital.

Good luck!

Plan Nine. Seen it. It’s great. Along with Ed Wood with Johnny Depp. And most recently I got my hands on a copy of Glen or Glenda.

Anyhoo continuing on,

I did think it through and the scale of an object increases exponentially as it nears the camara. That trumps the idea that you need to move in from 50 feet away.

Assuming the model is 10inches wide you can move the camara from a couple yards away to an extreme closeup in 1 second. Slow the footage down 50% so that it’s two seconds long and composite over a large field. The rate of exponential growth of the plane compared to it’s surroundings will make it appear like that baby is really cruising. If that still isn’t enough, then keyframing a basic scale change from 50% to 100% will multiply the speed at which it seems to be going but still preserve the exponential growth as well as the more realistic flight look that should come with moving the camara as opposed to the model.

I’m not going to pretend that I know exactly what I’m talking about here. I’m just brainstorming ideas. I certainly don’t believe you’d have to move your camara from 50 feet away.

Thanks a lot you guys, you have been a great help, i have also learned that sometimes when you dont have the correct resources certain effects will be cut from a scene. I will try to move the camera around the green screen instead of moving the plane.
