animation keyframes seem to have a nonlinear curve applied?

I am tryimg to make looping animatins but the begining and ending keyframes speed up and slow down. how can I make them linear?

thanks

Hello @Alanebell,

thank you for posting to the Forum!
To create a loop, you need to copy the first keyframe in the animation and paste it to the last position.
When the first and last keyframe in the animation are identical, looping is automatically created in Amberlight 2. To "fool" the ease in/ease out effect, you may try to render the animation without the last keyframe = if the last keyframe is on a frame #100, render the frames #1-#99.
