Six skills of mobile video shooting:

Try to shoot sideways, hold the phone sideways and hold it with both hands, which will make the fuselage more stable and reduce the picture jitter. If you shoot vertically, a large area of black edges will easily appear on both sides, which will affect the viewing quality.

Keep quiet, some people like to talk while shooting, but because the photographer is close to the microphone, his voice will appear loud and chaotic in the video, so try not to talk, even if it is much lighter than the sound in the environment.

Focus carefully when shooting, and try not to focus frequently when shooting, because when the mobile phone re-selects the focus in the process of shooting video, there will be a slow process from blur to clarity, which will destroy the smoothness of the picture. Therefore, before pressing the camera button, it is best to turn off the autofocus tracking function, that is, find the focus first to avoid focusing again when shooting.

Pay attention to the light In low light environment such as night, the video shot by mobile phone is prone to noise, which affects the aesthetic feeling of the picture. In the absence of professional equipment, it is best to use the surrounding lighting, such as street lamps, advertising lights at bus stations, indoor lighting, etc.

Try a strange angle. The important prerequisite for a beginner to become a master is "creativity". If you shoot from a normal angle, almost anyone can see anything, but if you want to stand out, you must try to change the shooting angle.

Make good use of post-processing, if you have a higher pursuit of shooting effect, you must use post-editing software. For Apple phones, iMovie is a good choice. The operation is very simple, running smoothly and getting started quickly. There are many special effects to meet the demand, which can quickly and conveniently cut several captured videos into desired effects.
