I understand that there should be almost sharp corners in the speed graph, but not purely. I mean, if you zoom in to the sharp corner a lot, you should see a smooth transition. Maybe I’m wrong.

The handles were edited by hand in both of my examples.

[Cassius Marques] “You’re probably changing the VALUE curve, not speed. I don’t recall max letting you change speed directly (or I never used that)”

Yes, you are correct in both cases. I just created a simulated speed curve to represent the value curve. The corner was sharp, but not absolutely sharp like in AE. A very small difference.

[Cassius Marques] “” What curves? If you mean the “handles” that set the incoming and outgoing speed. They will be matched if you lock them together like I said on my previous post.”

I was talking about the speed curve keyframes. I thought they should be locked in the method I used, but I’ll have a go with the method on your first post, thanks for that.

Hi Cassius. Thank you for your comment.

[Cassius Marques] “In a case without inertia, all corner should be sharp.”

I’m not sure what you mean by this. I made a little test, creating a similiar animation in 3ds max and then made a speed curve for it with a little trickery. The speed curve looks almost exactly same as in AE, but in close inspection there is no sharp corners, but instead the smooth transition that I wished for.

For now I just think that this is due to the mathematics used in AE. Somehow the curves from both sides of a keyframe are not perfectly put together.

Hi Darby, thanks for you insight. I understand what a speed curve is, but I still can’t see logic in the sharp corner. I still think (and might be wrong), that if the value keyframe is truly smooth, so should the speed curve go smoothly to the constant state.
