Can't Adjust Speed in Effects Controls
Hello! 
I'm trying to do a "speed ramp" effect. I've setup key frames in effects controls and tried to do it on the clip in the sequence and for some reason, it won't let me adjust the speed. When I go to move the bar on the clip in the sequence the little blue bar thing appears when I hover over the center but it wont let me move it. I also can't change the 100% level in the effects controls.
Any ideas why this might be happening are appreciated. Could it be I'm using an old macbook pro that's too slow?
