What is the relationship between shutter speed and frame rate in a camera?

The shutter is the exposure time of each frame; The frame rate is the number of frames per second. The camera shutter cannot change the frame rate.

when shooting video with a camera, the faster the shutter speed of the camera, the clearer the captured motion. However, if the shutter speed is set too high, the motion in the video (including the motion in the picture and the motion in the picture) will become unsmooth. Therefore, the shutter speed is generally set to twice the frame rate.

for example, the frame rate is set at 25 and the shutter is set at 5; That is to say, for 1 second shooting, the frame rate is set to 25, the shutter is set to 5, and the shutter is opened and closed 25 times, each time for 1/5 second.

The shutter is a component in the middle of the camera and in front of the photosensitive element. It acts like a black opaque window, and only when it is opened will it let the light pass through and irradiate the photosensitive element to form an image. The shutter opening and closing time is the "shutter speed" set by the camera.

shutter speed is an important parameter for digital camera shutter. The shutter speed of different digital cameras is completely different. Therefore, when using a certain digital camera to shoot a scene, you must first know the shutter speed, because only when you press the shutter, you can capture a vivid picture by considering the start time of the shutter and grasping the release time of the shutter.

the frame rate refers to the number of frames of the picture refreshed every second, which can also be understood as how many times the graphics processor can refresh every second. For movie content, the frame rate refers to the number of still frames displayed per second. To generate a smooth and coherent animation effect, the frame rate is generally not less than 8; The frame rate of the movie is 24fps. When capturing dynamic video content, the higher the number, the better.

to increase the number of frames, the CPU of the camera needs to be more powerful, in other words, you have to choose a higher-end camera.

Extended information:

A well-maintained camera equipment can give full play to its effectiveness and take the best photos. In fact, the proper use of equipment is the best maintenance. If it can be used correctly, there will be no problems. Camera maintenance mainly includes the following aspects:

1. Add a hood to the digital camera to avoid strong light, and stick a transparent protective film when using it, which can effectively protect the camera screen from being scratched.

2. When shooting, do not aim the lens at the general sunlight to avoid damaging the CCD board of the camera.

3. In winter, the machine is prone to condensation when entering the room from the outside. Like the glasses usually worn, the correct method should be to put the digital camera in a sealed plastic bag.

4. When the user has finished shooting, it is best to take out the tape and remove the battery.

5. Try to avoid shooting in rainy and snowy days.
