Why a tiny cropped window reconrding is as large as if the whole screeen is recorded?

[Cherryblos]

I have a problem which I am unable to solve. Here it is!

My purpose is to save disk space and therefore I have recorded by OBS only the most important on the screen.
The size of the recorded area is app. 10% of the whole screen.

However both recorded *.mkv files are almost as large in megabytes.
What do I do wrong?

I supposed that the smaller recorded area would be much smaller, but so far I have not succeeded in that goal.

All of your hints and points of view in this matter are much appriciated!

The final file size for modern encoders depends on content. More moves of the small objects = larger file.
