Slight delay in composure shots

I’m using a composure shot with a media plate to achieve a green screen effect following this tutorial: Unreal Engine 4 Green Screen Tutorial - YouTube. The input is a render target, and my output is a different render target. My goal is to save snapshots of both the composited greenscreen and the original color image (my input render target). At specific timestamps, I am saving the outputs of both render targets as images with C++. However, in the animations, there is a slight delay between the input render target and the output composited render target.

Is there any setting I can tweak to get rid of this latency? I would like both the input and the output render targets to be from the same timestamp in the animation. Is this possible?

I’m currently working around this by using an additional composure shot that just takes in the original render target as input and outputs to another render target without doing anything, but this seems unideal.

I’m on UE 4.27.2
