How to reduce the noise of camera when shooting video with camera?

Methods to reduce noise and improve signal-to-noise ratio;

1, try to shoot in sufficient light, whether CCD or CMOS, the lower the illumination, the more noise, which is the easiest for you to control.

2. If your camera supports multi-field superimposed output, you can turn on this mode. This mode actually extends the exposure time to increase the exposure, but reduces the frame rate, and there will be ghost phenomenon when shooting moving targets (slow shutter is art, video is ghost).

3. Choose a camera with noise reduction function. A good camera may not have noise reduction function, and a camera with noise reduction function may not be good. See the focus and cost performance by yourself.

4. Post-process the video to reduce noise. Unless it is a professional program, it will distort the video while reducing noise, and the effect is not good.
