  • How to add keyframe without that annoying arc?

    Hey guys,

    How do you add a position keyframe without AE automatically adding an arc of movement?

    In other words, let’s say I have two keyframes for motion: start and stop.
    – Keyframe 1 (start position): 960, 510,0
    – Keyframe 2 (end position): 960, 510, 200
    Rather than my object simply moving on the last value (from 0 to 200), the middle number (which is not at the default 540) doesn’t stay at 510 — it does a huge arc to like 50 and then back to 510. I can change views and manually adjust the arc with the handles but it’s never perfectly still and it’s highly time consuming.

    Is there an easy way to delete/eliminate that arc?

    Thanks ahead of time.

    Sorry, I think I figured it out. In case anyone else needs it, right-click the keyframe and select Keyframe Interpolation. Then set Special Interpolation to ‘Linear’ rather than ‘Continuous Bezier.’

    Another solution, in case you want to keep beziermovement on x and z, would be to right-click on the position and choose ‘seperate dimensions’ – after that: just delete the y-keyframes since they are not needed.
