Animating a property across multiple clips
I want to create a montage of various clips of different lengths that run one after the other. I want the montage as a whole to slowly increase in opacity so that it fades in from black over a period of time (not the duration of the whole montage, it will just fade in for part of it and then stay at full opacity). For one clip, I would add keyframes for the Opacity control, but I can't do this across multiple clips. Is there a way to do this without having to render only my montage as its own project?
