How to remove a couple seconds off the end of a video in unreal?

Hello everyone! So I made the main menu screen following this tutorial:


I made a similar background for test purposes in after effects but made the animation come back around to the original position to make it a seamless / smooth transition when it loops the video in the main menu

The only issue I have is that there is a couple second pause at the end of the video then it proceeds to play it again. is there any way to remove this “pause” when looping a video?

EDIT: Just looked at my After effects file, seems that past 57 seconds it is just a pause. was wondering if anyone knew a quicker way inside unreal engine to remove 3 seconds from a video? As re-rendering, this file would take around 2 hours.
