Why does the video look “not very good” even when the sharpness is reduced?

Question

Video

Happy holiday everyone!
Help me deal with one problem: I shot a video on a dslr camera with standard settings, the video looked "like from a phone", set the sharpness and contrast settings to the maximum, but the situation has not changed - the picture is still exactly "like from a phone".
How do some bloggers manage to achieve the softness of the video so that it looks soft and beautiful, without this "life sharpness"?
In the editor, too, no matter how you paint, this "vital sharpness" catches your eye.
