How to shoot long videos with Nikon camera.

SLR cameras cannot complete long-term photography work. If you want to shoot for a long time, you should buy a video camera, or use a two-camera relay.

Cameras are different from camcorders. The camera will consider the sensor to work for a long time and carry out effective heat dissipation design. The photography of the camera is an additional function and its main work is instantaneous rather than long time, so there is no need to increase unnecessary heat dissipation. And increase the size.

Nowadays, the largest sensor of 4K cameras is only 1 inch, and sensors of this size are used on compact cameras. The smallest SLR is also an APS-C format sensor, so even if it is in camera mode, The heat generated by a SLR is much higher than that of a camera. Photography is different from the slow exposure of photography. Photography often has to work with high current in real time due to frame rate limitations, so as to ensure the picture quality of each frame, so the heat generated is very high. SLR cameras do not have a heat dissipation system, so the sensor cannot work under long-term high temperature conditions. It will accelerate aging or even burn out due to long-term high temperatures.
