Motion Blur Artifact in AE Project for Product Storytelling

I’m working on a creative project for a client (https://emiratesappliances.com/), where I’ve been given a set of product clips to stitch together into a compelling visual story. The concept involves imagining a rare appliance malfunction that would make the video curious and thought-provoking.

Here’s the problem I’m facing:

I’ve applied motion blur effects in After Effects to simulate a chaotic moment where an appliance malfunctions, but I keep encountering a weird artifact issue. The blur seems to generate ghost-like frames that don’t sync properly, causing a jittery look in the rendered output. I’ve tried adjusting the shutter angle, sample rates, and pre-composing the layers, but nothing seems to work.

This issue not only affects the quality of the story but also makes the scene less believable. Has anyone faced a similar problem or knows how to resolve it? Would appreciate any tips to ensure the motion blur effect runs smoothly!
