Advanced easing on keyframes?

[Greg Neumayer]

Update:
I’m closer to my goal with the discovery of pressing CMD-SHIFT-K (CNTRL on Windows) on a selected keyframe.

This takes me to a dialog box where I manually adjust the keyframe velocity curve influence. While not really a different mathematical equation, it allows me to change the default ease of 33.3% influence to something like 100%, which creates a more smoothed keyframe.

I’d still appreciate any input on applying true sine,quad,quint,expo,circ-type equasions to a keyframe quickly and easily.

Thanks,
Greg

Thanks Todd,
While these examples provide increased control, I think I may have to fill out a feature request and wait for this functionality to hopefully be wrapped in a nice “right-click on the keyframe” package. It seems like something everyday AE users would find quite useful.

These solutions (in your link) seem to work best on an entire layer, lacking control over individual keyframes. True, there’s a “time” element on the expression solution, but we’re definitely drifting away from everyday usage into over-complicated when we start to use code to even create the “keyframe”.

One last question, though. Can we use an expression to refer to a keyframe? I’d be halfway satisfied if I could use the expression to at least refer to a “named” keyframe. Then I could keep the visual continuity of the keyframes on the timeline and wouldn’t have to manually code the “when” portion that “time” refers to.

Thanks for the link.

Did you try Ian’s script or at least watch his tutorial? It’s incredibly simple; you jsut select a couple of keyframes and choose an interpolation type from a menu in a panel.

It’s been over 10 years since Penner had over a dozen of these settings you could use in Flash with a little jiggling. So I agree…it’s long overdue for Adobe to build that into the program.

I applaud this post….and I do LOVE Haigh’s plugin.

Life is full of funny particles.

[Greg Neumayer]

yes, yes. You missed it in my first post:
“I love my Ease and Wiz script that I use…”

but unless I’m missing something, it’s only useful in the context that you’ve described: grabbing a couple keyframes and then applying the script. And for that, it’s great. But Ian is stuck (I think) with the limitation that the script is applying to the entire layer’s keyframes. So, while the script does provide some relief by having some “only first keyframe” type of options, it’s working around the greater issue of a lack of control to be able to apply the math to keyframes as individuals. This is an inherent limitation of the broader topic of how expressions work and are applied to layers, which is why I think the only perfect fix would be for it to be a feature request that gets this math applied down on the core level of keyframes–and then shows up in the keyframe contextual menu (right-click menu).
(disclaimer: I haven’t installed EaseNWizz for CS5, only CS4)

An example from my own work flow would be:
My microwave whips in from the left, eases to an awesome looking expo stop. But then, I want it to slowly creep up while I add a few lines of text below it. When I’m done, I want it to do a gentle fall and fade-out. The problem here is that I can apply the expo whip-in at the beginning, but then it’s difficult to have complete control over the other keyframes to do other manipulations. I find myself having to split the layer. A solution, but not elegant or very flexible if I need to make changes to the motion later.

Thanks for the discussion, though. I’m not a mathematician, and would gladly eat crow if someone highlights my ignorance to the elegant solution.

Greg,

I couldn’t agree more. @Craig…right, it’s been 10 years since Penner’s eases came out. Seems like it would be a fundamental feature.

Greg, you’re right. There’s much time wasted in the motion editor. To compound the limited canned eases, you also can’t lock your ease. Eg: You bezier an expo for a position change, then later change the position of either point. Well now you have to reset your curve :-[

Have you used EaseCaddy? It’s a great tool. Does what you want AE to do, but in Flash.

did i miss somwething. I’m just switching from fcp 7 and can’t get my keyframes in premiere pro6 to stop drifting. argh. help?

thanks
