One layer Fade In, Fade out.

Hey I have a question. On the timeline view in storyboard pro, is it possible to have one opacity of a layer on one key frame, and then make it a different opacity on another key frame? So for example, 0 seconds in, the layer would be opacity 0%, and then 8 seconds in, the same layer would be at 100% opacity. Is that possible, and if so, how?

You can’t change layer opacity over time but between scenes you can
add transition effects.
