[Ms.beetch]

Thank you very much for your informative response Tom.
I followed the instructions as you indicated and sadly, nothing happened. So, I decided to re-read the instructions to see if I missed anything.
You mentioned clicking and dragging the transition to the timeline. I actually added transitions another way. I just highlighted the transition of choice and clicked.
So I decided to try your way. I opened the effects folder and clicked and dragged the transition to the timeline and presto, it worked. A transition was born again.
I still cannot access the transitions via the effects tab in the browser. I still get the message”operation not allowed”.
My friend suggested to me that perhaps the fact that some of my clips had been rendered may have effected the outcome. I do not however remember formally rendering the specific clips I was working with.
I adjusted the speed and a green line showed up on the top of the timeline. Now as I look at the same clips in my project the line has turned blue. Can rendering have affected my ability to add video transitions, as odd as this sounds?
In any case, thank you for your help. I am glad that I can resume my editing. My cousin, I’m sure, will appreciate receiving her wedding video sooner rather than later. Sincerly, Ms. Beetch.
