What are the main points of making a video courseware promo?

The video courseware promo is also shot according to the production of the promo. The shooting of Desheng Zhike has the following points.

Flat: refers to keeping the camera level all the time during the movement. If the picture is not kept horizontal, the fixed horizontal and vertical objects in the picture, such as houses, telephone poles and people, will be crooked, which will not only give people uncomfortable visual effects, but also cause psychological instability and anxiety. Adjust the level when shooting with a tripod, and adjust the level state in the viewfinder at any time when shooting with hands or shoulders.

Accuracy: refers to the skills of accurate framing and left picture focusing in sports photography, accurate composition, and attention to focus when shooting. When shaking the picture, you should stand in a good position according to the left picture, and then shake it from the beginning, which can not only ensure the even shaking speed, but also give consideration to the accuracy of composition when shooting.

Steady: It means that the picture should be kept stable and not shaken during sports photography, otherwise it will give people a feeling of dizziness, which will cause psychological anxiety. When shooting in hand, try to hold your breath in one lens or let your body find a relying point and support point. Try to shoot with a short focal length camera lens to reduce camera jitter. It is very difficult and basic to do this.

Uniformity: It means that during the sports photography process, the camera should move at a uniform speed, neither fast nor slow. When shooting with a tripod, it is necessary to adjust the damping of the tripod, master the shooting essentials when shooting by hand, and start and stop the action by increasing or decreasing the force.
