Why does the general video recorder appear smear in the case of insufficient light?
The video recorder also has a shutter speed, that is, when the light is very dark, in order to ensure the brightness of the picture, the video recorder will increase the shutter time, so that the picture taken is a blurred shadow, just like the photo taken by the slow door, and the characters have a sense of movement.
There is no way to solve this problem if it is just the picture of an ordinary video recorder.
But if it is a good dv or professional camera, this problem can be solved in the following two ways:
1, turn on the night shooting mode;
2. Manually control the shutter to an appropriate speed to increase the gain.
In fact, the principle of the two methods is the same, and the result is more noise in the picture.
