scene camera movement issues

What to do when the screen camera gets stuck and jittery when moved in editor with common tools? (such as middle mouse button or the hand tool)

Video with the effect (beg pardon the nonenglish voiceover, the effect is visible at 0:10). The person in the video is trying to move the camera in a smooth direct fashion, but is instead getting a very jittery sort of movement, sometimes to the point of it becoming impossible to move the desired direction.

Use the Cinemachine tools and instead of moving the camera directly, move an empty game object as an agent and let the camera follow it with a soft margin.

It is really just value tweaking - super easy-to-use tools.
