I created an edited version of my video (length 1 minute for smedia). The original is below it and is a lot longer. The clip below the shorter clip is locked and shows grayed out. However when I play the shorter clip on the upper timeline and fade to black it just keeps playing black until it reaches the end of the project on the lower timeling. It also does this when I render the shorter timeline. How do I tell the clip on the upper timeline to end at the end of the fade to black?
