user26800: I am familiar with the copy and paste attributes method for pasting effects on multiple clips, however when I tried this method to paste my opacity keyframes from one clip to another, nothing happened.
All I'm after is some animated opacity levels (start from 50% reach 100% opacity in the middle of the clip then at the end of the clip bring the opacity down to 0%). 
Question
Does paste-attributes not work for opacity? If not, what is a similar labor-saving solution I can try?

user26758: If you need to copy opacity effect with keyframes, you should select keyframes and press CTRL+C, then select clip on timeline and move playhead to time where you want to put first keyframe, then select effect controls window and click CTRL+V to paste. That's all.



In such way you can copy keyframes from one clip to another.
If you want to copy keyframes from one clip to a lot of other clips, you can create preset in such way:
