How to achieve the matrix-endless white void effect

we shoot on green screen

We shoot on the red, would that be a problem still?

My answer was going to be with some very f@#$%& expensive equipment.

Not your average job. Most people fake it like Dave said.

Tyler, I do this with green screen from time to time, as well as with white photo paper backdrops. You don’t need the green to be very large: just large enough to give some room around the actors, then you use “garbage masks” and matte controls and cropping tools to remove the rest of the original shot and have the new background fill it in.

If you look closely, it’s not a perfectly even white in most cases; it deliberately hints at a far-away vanishing point false “horizon” with subtle gradient shading, to imply more depth and to imply a “floor”. Otherwise, your full-body characters just look like they are flat pictures stuck onto the front of a white fridge door. Your actors are going to (supposedly) be inside a huge white globe, so you have to light them with large, flat, relatively shadowless, white lighting. Use large softlight boxes. You will want an overhead liht source to throw a little shadow directly under them, but this can also be faked in post, using the same alpha channel mask made by the green screen, just warped and adjusted in blending mode and fill color. It can be very convicing becasue it moves as the actor does, they are two identical tracks locked together.

Step one is grabbing a perfect key in the first place. Step two would be creating the white background in an image editor or however else you like. In Apple motion for example, the library comes with several pre-made white “limbo” backdrops or stages, with more or less of a “horizon” in them. When I make these in Apple Motion, I create a solid plane to replace the floor, and then the gradient backdrop for the “wall”. Use a color sampling eyedropper tool to make all the whites match. Use feathered edgs on masks and mattes to help blend the thing together.

Good luck! And remember, “there IS no spoon”.

That demo makes me want to buy Conduit!

I already shoot it, I just want to know how to change a green screen background to a white color in final cut or in after effects

Use the eyedropper tool to sample the green. Adjust parameters to clean it up.

Put the green track on video track 2 , your white or other color or background track below it.
Something so fundamental suggests you could really benefit from reading the built in manual. I walks you thru the steps very well.
