I upgraded from 2014 to 2015 edit pro. Use to be able to highlight 60 plays and make them all half speed in one go. They would adjust spacing and not over lap either. Now with 2015, I can only seem to be able to do one clip at a time. It is a long proccess with 60 clips (football game video), changing the speed and then readjusting the location to avoid overlap. Does anybody have any suggestions?
