I am running After Effects CC 2015. I have been using the version of AE with no issues until recently. I have placed a video file on the top of a composition to give it an old grunge filter effect. At first, the file works as it is seen within preview. However, when I change the blend mode certain frames change the colors to a green and purple hue. When I attempt to change the blend mode back to normal, the frame is now completely green. I have attempted to crop of these frames however they seem to randomly appear in different spots.
Any help is appreciated,
Change your blend mode to something other than "Exclusion"
I tried that but the colors still remain. Even when I go back to normal. I ended up using a different file and the problem went away. Might have just been something messed up in that specific video footage.
