I have a very shorts clip that show two crows, one on the left I want to get rid of and one middle right perching on a cross. The cross is grey with a few lighter stains. Behind the cross and crows, there are trees (not very bushy, brown and khaki colours) and a white:blue overblown sky. What I want to do is get rid of everything except the cross and crow, which I want to turn into a silhouette.
I just don't know where to starts. I know I need to use a mixture of keying and masking tools, but having started with the keying tools, I am getting totally mixed up. Since the piece I want to isolate (the crow and cross) is darker, I have this notion that I can temporarily apply an adjustment layer like levels or curves to make the darks darker and then key it out and invert the results. I also think I should isolate most of the other portions of the video I don't want to keep with masks, but I don't seem to be able to draw a mask directly on canvas (my first time and I did try in Premiere first).
