Is there a way to make an anti-gravity video effect (as if your floating in space), that can be done with a free program (or iMovie)? If so, how?

When no gravity effects are done in movies,it is done largely in camera If no gravity is being simulated, actors will wear tighter fitting clothing in order to prevent the clothing from hanging and thus killing the effect.

If a shift in gravity if needed, then actors will often wear loose fighting clothing so when the shift happens, the clothing can move to further sell the effect.

Manipulating gravity is pretty much never done in post production as it will require too much work and will not blend perfectly with footage of actors, so you either make the entire scene in 3D, no real people at all, or you do the effect in camera

eg alt text (spinning the entire set around)

Thanks, but I kind of wanted a way to do this effect at home.

a cheap post process intensive way to do it is shown in this video https://www.youtube.com/watch?v=r2QetF22Etw

though a full 0 g scene will require actors on wires where you will mask the wires out in post.

it is labor intensive compared to manipulating the scene which is why even huge budget movies such as inception used low tech ways of building a room inside of a steel frame and using a machine to rotate it, or for the 0 g scene, suspend the actors on wires and record in real time, then in post simply edit out the wires

It would be difficult to make it look good but you could green screen it. A lot of programs will use chroma key. If you're going to suspend yourself from a harness find some way to color or cover the ropes or cables. Just shoot the environment without the actor and use that for the background. Take your time and think it out and it might look ok.

It really depends on what you're trying to do. There are somethings you're not gonna be able to get to look right, but some simple things can be done with cheap programs. Is there a specific shot you're trying to pull off? You've gotta start with a specific idea and go from there.

Also, does this have to do with this contest?

Haha, no it doesn't have to do with that contest (I'm not doing that contest), but in that video you showed me, I'm hoping to pull off an effect sort of like the one from 0:46-0:50

Ah, well that might be something you'll want to do practically, not digitally. Maybe using fishing line or something to hold things up or pull them around.
