In the storyboard view of the project, select all the clips using Control-A
keys... then select the effect you want to apply > right click on it and
tell it to apply.... it should go to all of them.
There wasn't an option to reply. But knowing it could be done helped so I
selected the effect I wanted and right clicked and went to copy. I then used
the Control A mentioned which selected all the frames Then I pulled down
paste and it did it.
