UE5.2 How can I rendering a 19200*2160video without use "high-quality" option in multiple cameras?

Hello everyone, I’d like to ask a question about the movie render queue. I want to render a video in 19200*2160 resolution and then split it into 5 frames on After Effects to achieve a seamless video.

I have tested dividing the video into 5 segments using different cameras for rendering at 3840*2160 resolution. However, when I composite them in After Effects, the backgrounds of each segment differ significantly.

As far as I know, the movie render queue has a “high-quality” feature that allows rendering resolutions beyond 4K. Is there a way to achieve the seamless effect without using the “high-quality” option? Instead, I’d like to split the 19200 resolution into multiple segments using different cameras for rendering and then edit them together in After Effects to achieve a seamless result. How should I set this up?

I would appreciate any advice. Thank you!
