> "Split image into 4 parts

My iMac has 2GB of GPU memory because it’s for home-use. It’s insufficient size for larger image output. It can output a little bit larger result when its display resolution set down to 640px x 480px.

It still needed to split images into 4 parts for 720p high quality video.

It caused a side effect which each frame has a border at the joint of the parts."

You seem to be correct on why the frame is split into four quadrants.
