Linear keyframe interpolation and bumps in curvce
OSX – AE 8.0.2
I have some simple keyframes, text Z moving into a scene. Look at this screengrab. Between keyframe 2 and 3 there’s a BUMP in the graph. Like it is trying to bezier interpolate between the keyframes. So my text is doing a weird retrograde zoom in the middle.
This is happening with all Linear keyframes. On X,Y,Z axis. Scaling. Anything with linear keyframes
the kicker is if I go along and punch in a keyframe at every frame, AE takes OUT the bump and things work correct.

Good idea Dave. Keyframe 2 is Easy IN. So there’s no handle on the right side.
Also, I can make all keyframe LINEAR and I get the same bump.
What I’m now noticing in my experiements: it only seems to happen with big moves. Like a Z move where text flies in from overhead really big, and then lands, then drifts slowly along Z

In the “keyframe interpolation” pop up menu Spacial Interpolation was set to “continous bezier.” Setting it to “Linear” makes keyframes behave as expected.

I had a similar problem with Character walk cycles….It was Step, pause, step Pause, Set Pause. So the Key frames went like this, Position Keyframe move to different Position Keyframe hold to same Position Keyframe so on and so forth. I had every Keyframe Linear, but dumby After Effects step added Bezier Wobbling between the two same Keyframes…..I resolved it by selecting every other Keyframe and changing them (Aple Click or Right Click on Keyframes) to Hold where there should be a hold. It is ridiculous because Linear doesn’t mean linear in AE like it does in Flash.

is there a way to set the default to linear?

yep, got it. thank you.
