Transition only affects the second clip. Solution One
This issue was resolved in the JSX script update released on July 7, 2025.
Make sure that the installed preset package uses a JSX version of 4.0 or higher. For more details, please visit:
https://motionbro.com/blog/updates/important-fix-for-a-bug-where-only-the-second-clip-appeared-during-transitions/
You can check the JSX version by hovering over the preset pack thumbnail. This feature became available in Motion Bro plugin version 5.1.4. If you have Motion Bro 5.1.4 or higher installed and the JSX version is not displayed, try applying any preset and check the version again.
Transition only affects the second clip. Solution Two
If the JSX script version is up to date but the problem still occurs, it’s possible that you are using a single layer composed of several different pieces of footage. If you simply cut such a layer at the junction between two footages, this can cause issues with the overlap transition.
Not good
Make sure the first layer is a single footage, with enough duration after the cut.
Good
Transition only affects one layer
Before you apply the Overlap transition, make sure you have selected two layers in the timeline that you want to connect through the transition.
Quand je tente d’appliquer une transition “MOTION BRO” dans première Pro, le message d’erreur suivant “EvalScript error” s’affiche, et aucune transition n’est appliquée. Quel est le problème svp ? Merci
I tried to use your silicon one, and i have two overlapping layers, and the comp above it is way bigger than even the composition. I fi could supply a screen shot I would. This is happening with all of your over lap transitions, this needs to be fixed. I see you haven’t responded to other people, and that makes me worry if my issues will be resolved. Please respond.

No need. I think I fixed the problem, I was in After Effects 2024 and while troubleshooting, I tried switching to After Effects 2025 – and the transitions seem to be working as they should, now.
Thanks for the quick reply. I’ll reach out to that link if I have further issues.
I’m trying to use an effect from set 4 in the warp effect. the example shows a blur during the transition from one layer to the the other on after effects, however when i add the effect to my composition, it duplicates the layers and does not blur. can anyone help me?
Maybe you have motion blur disabled in the timeline settings.
