Pulling a good key from a green screen can be problematic when the footage shot is recorded in a compressed format, as nearly all “prosumer”camcorders do (I assume you’re not using a RedOne or Arri Alexa!) reduced color resolution and compression artifacts, while not obvious to the eye, make it very difficult to pull a good matte without green fringing.

If your camera has an HDMI or RGB output, try recording those outputs into an uncompressed format directly on your computer or a separate recorder capable of uncompressed recording, rather than to the memory card in the camera. This may mean some additional hardware and/or software, but there are a lot of good quality outboard video capture or recording devices that connect to your computer via USB3 or Thunderbolt, by companies like Blackmagic Design, Aja, etc. for anywhere from $150 – $1,000 (but, read the specs!)
