    On a recent episode of Better Call Saul, a car was gunning toward Jimmy in the desert. Obviously Bob Odenkirk couldn't really be in frame during such a dangerous stunt, so they had to use a green screen. They solved all the problems presented in the video by shooting the green screen on the actual location using the same camera setup and and the sun for lighting.

    Sometimes I feel like they're poorly greenscreened because the producer never actually wanted me to believe they were filming on location, and only wanted the shot to be convincing enough for me to suspend my disbelief. I am fond of some minor filming errors because it enables me to empathize with the film crew and get a perspective on what it's like to be there making the movie.

    The _exposure time_ part does not convince me at all. That would make sense *if background video played at a framerate=1/exposure time* but that just isn't the case. Once I have sufficient light+camera capabilities to achieve 30fps on the foreground video, I can simply match such value in the background video hence create a 1-to-1 map between the two's frames. This also matches with the so called blur issue continuing even later on in the video, which you can notice between his arms and body. Or maybe I am missing something. Let me know.

    At work, we have the weather wall. It's a big green screen. When we have school field trips, we show them the wall, but we also have a blanket that is roughly the same shade of green. So when we drape the blanket over the kids body, they become a floating head. Ah the fun you can have in television

    Another issue is when you have the green screen reflecting off people's skin. Either it keys out a slight part of them, or you just have this weird slight green going on
