I've conformed a project shot on alexa and anamorphic lenses to 1920x1080 timeline. Now i'm selecting one of the clips in the timline, and selecting create batch effects. The resulting node graph the original clip connected to a few timewarps and resize and a back clip (the one that was on the track underneath in the timeline) comped together. The back clip works fine but the main clip node seems to be black. The clip works fine on the timeline but for some reason is black in batch fx. What am i doing wrong? This is flame training edition installed on a trashcan macpro with dual firepro 700 gpus. Any help much appreciated!
