Is it possible to start two lightning effects on the same clip at different times in CS5?

Mar 9, 2013 9:40 AM

Tags: #effects #effect #lightning

I put two lightning effects on the same clip. I want to start them at different times. I don't see how to do it. I can't keyframe them.

Do all effects have to start and stop at the same time, the beginning and end of the clip?

    I can't keyframe them.

     

    Why not?

    So keyframe a set of parameters that make the effect go away -- like negative values for start and end points that will take the effect out of the frame.

    If you upgrade to CS6, you could add adjustment layers above the sections of the main clip that you want to have the effect, and then put the effect on the adjustment layers.

    There is no keyframe stop watch by the effect.

     

    There is a stopwatch by every single parameter of that effect.

    Kinda works but let's say you want the lightning to suddenly shoot out of someone's eyes. If you start it off the frame when you bring it back there is a tween trail.

    Not if you use hold keyframes and set the last out-of-frame position keyframe exactly one frame before the out-of-eyes position.

    but not on and off or show

     

    Turn Width and Core Width down to 0 for no show.

    Width only goes down to one, so the effect will never vanish completely.

    Hence also turning down Core Width.

    That still doesn't make it vanish completely.  Overlay it on a dark frame and you'll see what I mean.

    Well, then we're on to using two adjustment layers, one for each.

    Yup, forgot that.

     

    (This is why I still believe CS6 is different enough to warrant it's own separate forum.  It offers a fundamental shift in how we approach a lot of editing tasks.)

    Like Harvey Two-Face, many of the decision makers are of two minds about that.  As a mod, having CS6 lumped in with CS5.x makes my job a little easier as far as moving posts around, so I'm not going to scream too loudly for a new forum, even though a strong case can be made for having one.

    I can see that.

     

    But I think separate would be better for users, and that user needs trump mod needs.

    At the risk of getting too off-topic, I will say that a strong case can also be made that the versions are enough alike that keeping them together helps users more than splitting them up.  So my lack of cheerleading for split forums isn't just due to my well-documented laziness.

    If the fx parameters and key frames cant do it easily...I would use a nest.

     

    Put the clip in a separate sequence of its own.  Apply 1st lightning bolt there.

    Nest the clip back to edit sequence ...add next effect.
