Auto add Ease at the end

Lottie in Mobile
1

Hi everyone, I found that when I export json using bodymovin and preview animation on IOS, it auto added ease at the end (slow down). How to fix it? (I only use linear keyframe)

Hey @Tu1

Have you tried exporting using the LottieFiles for After Effects plugin? You can get it here: LottieFiles for Adobe After Effects: Streamline your animation workflow

If the issue persists, feel free to share your .aep file with us at support@lottiefiles.com — we’ll help troubleshoot it further.

Hello @Tu1,
This is a known issue with Lottie on iOS—some animations default to ease-out even with linear keyframes. To fix it, ensure all keyframes explicitly use "easing": "linear" in your JSON. Also try exporting with the LottieFiles plugin instead of Bodymovin, which may preserve easing more accurately.
