I've been looking and seeing others with green screen issues, i used the chroma key function on this program a couple years ago and it worked flawlessly - now its almost impossible to use, so frustrating - its either gray or, when i make adjustments it starts cutting away at the subject im trying to use. I've tried everything. I built a room dedicated for this and painted the entire room green thinking i had it all worked out. if anyone has a solution please post - ( different video formats maybe? ) i upgrade with magix every year but if this where their product ended up..... well im out.
