corridor format. (IVMS: Hikvision) How to output to a quad without completely filling the cell?

Question

CCTV

Essence of the question.
There are 4 Hikvision cameras. Recorded in the registrar (Hikvision).
1 of the cells was transferred to the corridor format (flipped vertically).
When outputting to a quadrator, all 4 cells of the camera are filled completely and it turns out that the camera with the "corridor format" is stretched to the entire cell.
Is it possible to draw its output "without stretching" (vertiac, black stripes on the sides).
