At present, most Nikon digital SLR cameras have the function of recording video. To shoot video, first switch the SLR camera from viewfinder view to display view, and then set the focus mode, including auto focus and manual focus, depending on how to use it to watch and shoot video.

Then set the camera dial to recording mode, and then click the button marked with a red dot on the camera (this button is the recording button) to start recording. At this point, the time countdown is displayed on the camera display. Generally, a video can be recorded for 20 to 30 minutes, depending on the brand and model of the camera. When recording video, press the red button again to stop shooting.

In addition, it is not recommended to shoot a video at once, but it can be shot in several segments, which is helpful for later viewing and editing. I hope this answer is helpful to you.
