What are the processing methods of moving pictures in focal plane?

It should be noted that the motion of the object can be three-dimensional, and the motion in three directions of XYZ axis can make the space look fuller. Below: Analysis of Forrest Gump's mother's walking track in front of the camera (this is a scene from the first 10:20 second of the film, but it is not the best example because the camera is still moving).

Although there are not many actions in this way, the picture is rich through the design of the actor's position. People's walking in and out, approaching and going far, and the direction of movement can all be used to create movement.

Method 2: Focus on the motion of the camera.

It is possible that the camera moves in space. It can move on various tracks with the help of tripod, track, elevator or human body. This kind of exercise is easier to explain things and can also control the observation order well. From the picture alone, if you think the camera is too simple to move forward, you can add a tripod head at the same time and use the elevator to raise it. Of course, the more complicated the practice, the better.

Mode 3: Camera and object move at the same time.

The first two methods are usually combined to create smoother and richer images. This kind of action needs more detailed design and scene scheduling control. It often has such a feature that different angles and scenes appear in the lens, resulting in various levels of depth effects.
