After Effects Beta 2025.2.0 - Eased keyframes in Speed Graph Editor won't follow desired speed curve

Question

I'm trying to give a speed acceleration (Vox style) to a vertical bar for a bar graph. The problem is that when I try to do that it has no effect in the speed graph editor. I'm able to achieve the speed curve I want when I apply it to the position property of the moving rectangle, but not the height scale property of the bar. Notice that I pulled the handle of my second keyframe for the vertical bar all the way to the left to have the bar begin scaling up fast and then slow down to a stop (like I did for the rectangle position). But the speed scale curve of the vertical bar hasn't changed. That's my issue.

Hi @ninose11

The issue appears to be that you're grabbing your Rectangle's xScale's bezier handle. The tricky part is that the X and Y values are overlapping each other since they have the same value. Two ways to workaround this now that you have your keyframes set are:

Take that handle that you've been pulling and lift it up out of the way to reveal your yScale's handle.
Relink your Scale property and drag the handle again. This will allow both curves to be adjusted when you grab that xScale handle, but since the xScale value doesn't change, you will only be affecting the yScale's speed.

Let me know if this does the trick for you!

You're welcome! And separating Scale dimensions is a great feature request. You can head over to the Feature Request section of the forums to search for one (I suspect at least one already exist) and to add your vote to it.

In the meantime, if separating scale is something that you want for more control in animation, a common rigging method is to add a couple Expression Control sliders to a Null Object and to link xScale to one slider and yScale ot the other.
