How Do You Shoot Depth Of Field On A Camera Which Camcorder Can Create Shallow Depth Of Field?

Which camcorder can create shallow depth of field? - how do you shoot depth of field on a camera

I want to blur videos with the blurred background (focus on the foreground and background to shoot). Whether the consumer or semi-professionals, the camera can create this kind of effect?

I like shallow depth of field, so that the person is not as flat as in the video.
