Camcorder speed key
Using the speed key, we specify how fast we want the video to be recorded.
If the video is silent, the speed is usually دوربین سیم کارتیset at 18 frames per second, meaning that only 18 frames per second will be recorded at fixed intervals.
If the film is eloquent, the film is usually recorded at 24 frames per second.
In this way, if the video is shown at a speed equal to the speed at which it was recorded, the movements seem natural.
If they want the movements to be faster than usual,دوربین خودرو ie Fast Motion, they set the speed to a speed lower than what was said above, for example, 9 frames per second, and Lee when displaying faster, They usually display normal speed.
And if they want the movements to دوربین مداربسته خودروbe slower than usual, ie Slow Motion, they set the speed to a higher speed than what was said, for example, 36 frames per second, but when displaying at a lower speed, usually the speed. Regular display.

Before shooting, the shutter size and in some cameras the shutter speed should be adjusted according to the speed of the subject.
The speed of the subject is either normal, such as دستگاه شنودwalking and cycling, or the speed is too high, such as the movement of a car, or the speed is too high, such as the movement of a train or a plane.
The higher the خرید دوربین مداربستهspeed, the more if دوربین مداربسته بیسیمthe shutter is adjusted in size and number, the lower it is, and if it is adjusted in degree, the lower the degree.
