as you can see in the frame from the video, the grids and the image are worse visible (the additional ring is not visible)
how do I change the contrast of a video?

By default, videos are created using lossy compression which will remove fine details. Consider
img = ...
v = videowriter('filename.avi', 'Archival');
open(v);
writevideo(v, img);
close(v);
to create a video with no compression.
