Green Screen shot question

[AlexD]

I want to shoot people walking in a green room and then make them much, much smaller in post for a landscape shot. I'm assuming this is possible. Can anybody help me out?

Thanks in advance

yeah, just key out the green, scale the clip down to size you want and place them where you want in the composition. The most important thing to do is pre-visualize. Shoot your background plate (the landscape shot) first, noting where the camera is in relation to the horizon, how the light is coming in, ect. Then shoot your subject from the right perspective with lighting that appears the same, so that it will blend in post. If you don't get this right it will always look a little off.

If the camera is moving (in the landscape shot) you will have to use after effects or a more powerful effect program. You might want to use AE in any case. Good Luck, this might take alot of trial and error.
