Keyframes in scipts question
Hello everyone !
I’m currently working on a script that imports keyframes into after effects.
I figured out how to create a keyframe, set its interpolation to bezier, how easeIn and easeOut works, but there is one last thing that i can’t understand.
Right now i’m doing this to add and set eases :
var easeTestIn = new KeyframeEase( 2000, 20 ) var easeTestOut = new KeyframeEase( 2000, 20 ) var keyFrameIndex = transfoNullObject.transform.scale.addKey( posX/framerate ) transfoNullObject.transform.scale.setValueAtKey( keyFrameIndex, [ xValue, yValue ] ) transfoNullObject.transform.scale.setInterpolationTypeAtKey( keyFrameIndex, KeyframeInterpolationType.BEZIER, KeyframeInterpolationType.BEZIER ) transfoNullObject.transform.scale.setTemporalEaseAtKey( keyFrameIndex, easeIn=[easeTestIn,easeTestIn,easeTestIn], easeOut=[easeTestOut,easeTestOut,easeTestOut] )
This indeed sets easeIn’s speed, but not easeOut’s. It only sets the influence, speed is always 0 no matter what i do.
Can someone see what i’m doing wrong ? Or missing when creating my keyframe ?
Thanks.

Hi Damien. I tested this and I notice that you can only set the speed if you have any keyframe on that side. If this keyframe is the first, you can’t set in speed. If it is the last, you can’t set out speed.

Hi
Indeed, but in my case, i do have keyframes before and after the one i’m trying to set.
When i look at the result in graph editor, i see the keyframe with a correct easeIn, the easeOut is flat (speed = 0), but its influence is good (length between current keyframe and the next one is ok)
I actually implemented this for xPosition, yPosition and rotation, which are 1D properties, unlike scale which is 2/3D and it works well.
Only speed from outgoing tangents can’t be set, which is weird.
