Bezier Handles in graph editor
on Jul 24, 2009 at 3:33:35 pm

I am fairly new to AE, having used mostly Shake in the past. I have an issue where my Bezier handles appear inconsistently. I set the keys to Continuous Bezeir and sometimes the key will have a handle and sometimes it will not. Is there a handle visibility toggle I am missing? I have searched the help and web in vain.

thanks

What happens when you put the timreline cursor on the keyframe whose handles you want to tweak?

When I highlight the keyframe it will glow yellow, but no handle. I can visually see the slope of the curve change when I toggle from linear to Continuous, but I have not handle to control the slope. perplexing.

I should also mention that I am losing the Bezier handles in the value graph, not the speed graph.

AE Help has this to say about such things:

"Two types of graphs are available in the Graph Editor: value graphs, which show property values; and speed graphs, which show rates of change of property values. For temporal properties, such as Opacity, the Graph Editor defaults to the value graph. For spatial properties, such as Position, the Graph Editor defaults to the speed graph."

Could that be the problem? I found that tidbit of info here:

Nope, not that. I actually came across that page this morning while trying to figure this out. I think it has something to do with the zoom magnification within the value editor, but that is just a guess.

I have also tried switching to the curve tool and converting to try to pull out handles. Doesnt' work. Also tried the suggestion of using the 'G' key to pull out the handle. No luck there either.

thanks tho

Well, I've run into this often, and it took me a long time to figure out.

AE doesn't allow bezier handles for linked multi-spatial properties (Anchor Point, Position, Orientation, Scale). Your options are to either try to make do with the speed graph or separate the property dimensions.

Right click on the property and click Separate Dimensions. Now if you for example applied this to Position property you would get position x, position y (and position z if 3d) which you can then animate separately using the bezier handles.

It actually isn't AE's fault, it's just many other programs separate the dimensions by default. If you were allowed beziers with multi-spatial properties you would run into problems like the gimbal lock.

Do you know why some linked properties won't let you separate the dimensions? Specifically, I'm working with a text animator position property. The option to separate dimensions is grayed out. Also, there was another multi-spatial property that wasn't letting me separate dimensions either, but I don't remember what it was... I know this works with the basic transforms, but is there a way to do it with other properties as well?

Thanks.

Yep, this question and its answers helped me today, too. Thanks, Dave, et al!

BTW, it helps speed my work to know these 2 shortcuts for changing keyframe interpolation:

Set a key's interpolation (so you can get bezier handles): Ctrl+Alt+K / Command+Option+K (Mac)

TOGGLE a key to Hold or Auto Bezier: Ctrl+Alt+H / Command+Option+H (Mac)

Also, I found it helpful, if I separate the dimensions, to just get rid of any dimension I wasn't animating. I'm making an object bounce vertically right now, so I got rid of the X position keys by clicking the little stopwatch for X.

If you separate dimensions on one layer, you have to do it on the other layers in order to see the handles. Thanks Touko for the lead.

There's another cool tutorial on how to work with bezier keyframes inside the graph editor, if you're interested in checking that out:
