You have three choices here, either to do a 2D track, a Planar Track or a Matchmove. As we talk about in Visual Effects For Directors, Planar Tracking is not very good for this. 2D tracking can work well if you track a point on the horizon and pin the new background to it — so we put some markers out there. The best is a matchmove — then you can build a real 3D set out there.
ISSUES: We didn't really control the exposure outside, but it wouldn't have been difficult. We'd like to see the green screen expose higher. We also like to saturate colors a little higher in the camera because it compresses slightly better.
TRY THIS: Do a matchmove, possibly even without using the markers outside the window. If you have enough to track inside the room, you don't need a single marker on the green screen, which can be liberating.
