The green background on my AVI video is flickering between green and black, there are also big outlines of green around my cubes, yet I haven't included any effects or touched any settings, simply just put my AVI video into the workspace, why is it doing this?
Even when I add a keylight effect the green becomes transparent, but there is still a black flicker, just as shown in the video.
Please help, and please see the video I recorded as an explanation.
Thanks in advance.
