    Hi all. Need to animate a ball in After Effects CS5.5, and have watched various Lynda videos about easy-ease in/out etc and the graph editor, but it still slightly befuddles me.

    Attached is a screenshot - I cannot for the life of me, work out what the two yellow squares represent (I know they are keyframes) and what the bezier handles affect, when pulled and pushed... :confused:

    What is "influence"... ?

    Any advice would help me, and thank you! :)

    If you grab the yellow circle, then drag it, the corner will become more smooth, I think - that's how masks work anyway.

    Uhm, yep, but this is not a mask...

    Yes but the theory of bezier curves remain the same.

    When pushed and pulled you are essentially creating your own ease in and out.

    If it has a really steep curve it will speed up/slow down very fast before the keyframe but if you have a smoother less steep curve it will slowly change the speed before the keyframe.

    Hope that helps. I'm not exactly on top of my terminology!
