For some reason I can't drag footage and/or an Effects Preset (background) into the composition window. When I do this, only a black screen appears (although the clip appears in the Project window and the Timeline). When I play the timeline, the Comp Window just shows black (however the wireframe "X" appears as though there is a clip). I checked the Mute button ("eye"). Are there any other "mute" functions that might be preventing the clip from being seen in the Comp Window? Or some command that I accidentally engaged?
I've done this before with no problems. Not sure what I'm missing.
