Everytime I try to use the mask in after effect the image does not show up I follow the tutorial and it still won't work. Am I missing a step? I don't know what's happen all the tutorials say that I should just mask it and the image show appear but only the outline of mask shows up. What am I doing wrong.
You will have to provide comp settings, project info, what footage you are working with, system info, screenshots. also tell us what tutorial you are referring to. Your post is far too vague and completely devoid of any relevant info.
