I’ve included a still from a recent green screen shoot – this is on neutral settings, STD-5 – the key worked fine, but there’s too much detail on their faces – I’m not expecting cinematic, but I’m also not expecting the coarseness it’s throwing up.
Although wouldn’t editing on a 1280x720p proxy then not give me the screen real estate to zoom in (I know it won’t have the quality, but that compared to 3840×2160…)
