Just shot a video using a greenscreen. Using Hitfilm Chroma Key got reasonable results except that some items in the video contain colours that match the greenscreen - argh! Just didn't notice. Is there any way to mask part of the greenscreen area or use cookie cutter or something. Never really used greenscreen before. Would really like to avoid a reshoot and even if I did I doubt I could find a single colour that doesn't match items that must be used. Any solution, thanks.
