I have a timeline with over 200 still events, all the same length with dissolves of the same length. I've keyframed pan/crop attributes for about a quarter of the events and now I've decided I want to change the length of all my events without affecting the dissolve length. If I change the length of one event, copy it, select all, and paste event attributes, the same pan/crop moves are pasted from that event--not what I want here. I'd like to just change the length of all my events without affecting any other attributes. Any suggestions?
